=== wow is now known as tho [00:58] Hey [00:58] Does anyone know how to run .cmd files with wine? [00:58] I thought, it would work using wineconsole. [00:59] But when I enter the name of the .cmd file, nothing is displayed - except for a new prompt line. [00:59] IlGiocatore_ubun: what is a .cmd file? [01:00] Something like a .bat file, I guess. [01:00] Windows Batch files, if I'm right. [01:01] Something like Windows shell scripts. [01:01] No, .cmd files are not suimple bat scripts, better ask in #winehq [01:01] I did asked there, but nobody has answered yet so I thought maybe someone in here knows it too. :) [01:01] definitely ask there as I am not even sure if those _should_ run [01:02] Maybe I should look up the difference between .bat and .cmd. === kostkon_ is now known as kostkon [01:45] any good 5g hotspot with port forwarding? [01:59] How do I know if file transfer really completed? The "Moved 893,483 files to 'LG external drive' pop up still persists. I'm not sure if I can remove the drive now [02:00] Run a checksum on the file and confirm it is the same as the original. [02:00] backthen: with the command "sync" you force to write stuff to the disk, when all data is written, the command completes. after that I just make sure another time that really everything is written by reissuing the command [02:01] backthen: you could try 'lsof' in a terminal, to see if the files are open or not; you could collect an md5sum run over the entire source directory and verify that on the destination directory [02:03] ok I'll have to learn those commands. How come Ubuntu doesn't give some visual feedback? Around the file explorer's address bar, there is still a circle (filled) to indicate some writing operation is/was going on. [02:07] backthen: That would (likely) be a bug in Nautilus / Gnome Files, I think (or maybe some of the UI libraries it uses). You could check their bug tracker to see whether soemone already filed it and if so, what the status of fixing this is. [02:08] sync? [02:08] Maybe I can try unmount this external drive? Presumably if everything completed, the unmount would succeed [02:09] if you eject in nautilus, it will send a sync command, before it actually ejects [02:11] ok. Yes in nautilus. Nautilus's eject button is labeled 'unmount' if you mouse over. But I guess underneath, if I press it, it'll issue a sync before really unmount [02:12] I installed nvidia drivers and even tho it runs better it still runs with some lags like there will always be slight freezes sometimes [02:15] marcopolo1_: did you make sure that the nvidia driver is in use, not the foss driver? [02:21] murmel: yeah i did, in additional drivers it says nvidia 515 [02:21] The game runs fine but like it isnt really playable [02:22] On windows it runned better === chris15 is now known as chris14 [02:27] marcopolo1_: sorry, don't know too much about how to verify that nvidia runs well. never had a nvidia gpu [02:46] " the game" [03:52] rx2t56j [04:32] hi folks [04:32] my desktop is gnome shell. [04:33] Not sure what happened, but my desktop icons, normally (always, forever) would be on the left side. But they've disappeared. They show up when I click on Activities. I've looked at Settings, but can't figure out what to do to get them back. thanks for helping. [04:38] johnfg: https://linuxhint.com/hide-dock-in-ubuntu/ [04:46] toddc: Thanks. For some reason, the Settings/Appearance didn't work/change things back. However, using the cli worked. I appreciate the help. [04:51] hi ubunters, my desktop takes a long time to show the login and let me back in after screens are locked. It litterally takes at least 30 seconds . Is there anything I can check to improve this? [05:18] dmesg [05:23] I have a partition I want to resize, before I make backups of partitions with DD to another drive, obviously as files like so : dd if=/dev/sda1 /external_disk/sda1.img; and then I boot the machine with some livecd image, resize the partitions AND THEN restore the fs with my previous backup files: dd if=/external_disk/sda1.img of=/dev/sda1, and in [05:23] the same vein with other partitions. Now, I know that ext4 uses inodes to keep its structure, and they are logical but underneath it uses device blocks, and if the blocks change, (and with partitions being resized they will change), will this eff up my fs? [05:26] what I want is actually a certain partition smaller, and the next one to assume its space [05:34] If you have backups boot https://gparted.org/livecd.php [05:34] Make your changes and be happy === wolfdale837 is now known as wolfdale83 === cedric is now known as Guest1870 === diskin is now known as Guest4873 === diskin_ is now known as diskin [07:16] is there a way I can get my grid of images to be more than one inch high (in files) I used to be able to doom in to actually see what's in the screenshots. This is unworkable. [07:20] ask your distrib channel #ubuntu #mint whatever, or try anothe filemanager, like thunar or gnome/xfce pcman-fs === yCrazyEdd is now known as CrazyEddy === jfelici is now known as evaluator === SteelRose_ is now known as SteelRose [08:41] hi, what do i need to do to clean up the snaps on my system to the absolute minimum before the system starts breaking? it's taking up gigabytes of space which i don't have [08:41] using 22.04 LTS [08:42] (which started somwehere around 14.04 LTS and updated/upgraded since) [08:43] after i removed all the non-current snaps, it still uses 6.3G at /snap/ and 3G at /var/lib/snapd/ . needless to say that i did not request to install any of them. [08:45] for reference, this is what snap list --all shows: https://0x0.st/odNK.txt [08:46] (why do i need 5 gnome versions?!) [08:46] (and i don't even use gnome...) [08:49] You can completely remove snap without the system breaking, if you wish: https://ltsp.org/guides/snap/ [08:53] alkisg: thanks. how do i know which functionality goes away by removing each snap? the only one i can be sure of is "firefox" (which i actually want to keep, though i'd prefer non-snap instead if possible) [08:54] avih: yeh the link installs the non-snap firefox version, from the mozillateam ppa. I don't know about the other snaps, I uninstall it myself as it doesn't work at all in my use cases [08:54] alkisg: but how do i know what would break by removing them? [08:54] firefox is just one. i have more than a dozen snaps installed... [08:55] You'd read the package description, but as I said I'm not using snap so I can't help with "where to find it". Wait for others to answer that part if you wish. I do know nothing broke for me in all flavors when I uninstalled snap. [08:56] so basically, you're saying "if you want to remove all snaps, this is how. but i don't know what things will stop working for you" ? [08:57] Yup, and additionally "in a default installation, when removing snap, nothing breaks for me". [08:57] right [08:58] well, i need to know what stops working before i do that... [09:01] And that's the "wait for others" or "read the package description" part that I mentioned. I didn't claim that I had a fully documented answer for all your questions, I just wanted to mention a relevant idea. [09:03] yup, appreciated. [09:04] so how do i find what depends on which snap? (including inter-snaps?) [09:05] e.g. of the seemingly 5 versions of gnome here, what stops working if i remove the first (gnome-3-26-1604) ? [09:05] (should i be worried that i seem to have 16.04 snaps?) [09:06] (never looked at it closely before, till apt told me it can't update because it ran out of disk space...) [09:06] again, for reference, snap list --all prints this https://0x0.st/odNK.txt [09:30] alkisg: if i understand correctly, that script does these: 1. remove mate stuff if needed (which i don't have). 2. replace firefox snap with firefox from mozilla PPA. 3. remove snapd. 4. symlink the new firefox to the snap location. right? do you know if i can remove all snaps except firefix and expect it to work? (i _think_ i only care about firefox, but not sure...) [09:32] avih: I think firefox snap depends on the core, themes, portal, hunspell etc snaps to function properly [09:32] thx [09:33] are there dependencies of stuff outside snaps on snaps? e.g. do some apt packages depend on some snap packages? [09:34] avih: if you give us a list of all snaps you have installed, we could even help you better ;) [09:34] no [09:35] murmel: i've installed none that i know of, and yet snap list --all prints this https://0x0.st/odNK.txt [09:35] (that's after i removed all the non current ones. this system started and upgraded since 14.04 LTS and currently at 20.04 LTS) [09:36] sorry, currently 22.04 LTS [09:37] avih: k, so the things you could be interested in are snap-store, firefox and gnome-system-monitor which means, you need to install the ppa firefox, and apt packages called gnome-software and gnome-system-monitor ;) [09:37] murmel: i don't use gnome (i still use the old unity, and if needed, i also have xfce installed) [09:38] also, define "you could be interested in"? [09:38] okay, so afaik you still want those, but not sure, as gnome-system-monitor should be also used in unity [09:38] (i mostly use this system headless though) [09:38] avih: that are the actual software you installed, the rest are dependencies [09:39] not sure i understand [09:39] i don't recall, but i think firefox was installed with the system without me installing it explicitly via apt? (but that was years ago) [09:40] avih: firefox was moved from a deb package to snap with the move to 22.04 [09:40] so what does this mean? " the actual software you installed" [09:41] avih: the software which is "front facing", which means that is software which you interact with, which you maybe use [09:41] idk how to explain it otherwise [09:41] i didn't install gnome that i recall, and same for firefox (i don't care about gnome, but i do about firefox) [09:42] you mean "the things i want to keep" ? [09:42] avih: well what specifically "gnome" are you reffering to? (the gnome snaps) or gnome-system-monitor? [09:42] avih: the thing you "may" want to keep [09:42] idk if you want to keep firefox for example. (I mean I know you want, but still) [09:42] it's something you maybe don't want [09:42] as you use chromium or whatever [09:43] well, my first issue is that i have this list of snaps installed, not by me, and i want to remove as much as possible, but i don't know exactly what each name refers to (Except probably firefox), and i don't know what depends on what [09:44] so as I already said, the software which is installed are these 3 (firefox, gnome-system-monitor, snap-store) the rest are just dependencies so these softwares can run [09:45] snap store is a front-end for deb repositories and snap packages, gnome-system-monitor is a system monitoring tool (duh) and firefox is firefox [09:46] of the things on this list https://0x0.st/odNK.txt i know prefer to keep using firefox (possibly from elsewhere, like mozilla ppa), i don't use gnome desktop, i don't think i use gnome system monitor, i don't know whet depends for instance on "gtk-common-themes" (only other snaps? or also non-snap gtk stuff?) [09:46] what is gnome-system-monitor? [09:46] avih: as I said above, unity uses gnome-system-monitor [09:46] and what is snap-store? [09:46] as it's monitoring tool [09:46] oh [09:46] like task manager of sorts? [09:46] yes [09:46] i.e. a user gui tool? [09:47] yes [09:47] right, i don't need it [09:47] and gtk-common-themes are themes, so the software can give you a correct window with information on it, so a dependency [09:47] of what? only of other snaps? or also of non-snap packages, like xfce? [09:48] everything in snaps is only for snaps [09:48] hmm [09:48] that's why you can purge snapd, and nothing is broken [09:48] so if i have xfce, it does not depend on anything in snaps, yes? [09:48] even unity [09:49] so basically i'd lose firefox (and gnome desktop, and gnome-system-monitor), and that's about it, yes? [09:49] you don't lose gnome desktop, as that's not installed [09:49] oh? [09:49] what's called gnome, is the toolkit [09:50] so that the windows of software can be shown to you on the screen [09:50] hmm.. why do i have 5 of them? [09:50] i though that's gtk? [09:50] gnome-3-26-1604 3.26.0.20210629 104 latest/stable/… canonical** - [09:50] gnome-3-28-1804 3.28.0-19-g98f9e67.98f9e67 161 latest/stable canonical** - [09:50] gnome-3-34-1804 0+git.3556cb3 77 latest/stable canonical** - [09:50] gnome-3-38-2004 0+git.6f39565 119 latest/stable canonical** - [09:50] gnome-42-2204 0+git.c271a86 44 latest/stable canonical** - [09:50] dont spam ;) [09:50] give it a min, then you are unmuted [09:51] but yes, that's gtk, in the snap world, they are called gnome [09:51] testing... [09:52] you are back [09:52] thx [09:52] so why do i have 5 of those? does firefox need them all? [09:53] and i have 4 cores... [09:53] avih: no, but the gnome-3-26-1604 is for example an old residue from your 16.04 days [09:53] why is it not removed automatically the same way it was added automatically? [09:54] and how do i know what breaks if i remove it now? [09:54] avih: no idea, I assume nobody implemented a way to remove old stuff (which are not disabled) [09:54] snapd will complain that it's needed [09:54] for example you can't remove core as of right now [09:55] you nean if some other snap depends on it, then i wouldn't be able to remove it? [09:55] but you should be able to remove core18 afaik [09:55] yes [09:55] avih: same with apt and deb packages [09:55] how do i list which snaps depends on which others? [09:55] you can't [09:55] huh [09:56] avih: can you give me the output of "snap list --all | nc termbin.com 9999" [09:56] so the only way to test whether snap X depends on snap Y is to remove Y and if it complains then something depends on Y? [09:56] https://0x0.st/odNK.txt [09:56] yeah, or you know a little bit about packaging (and your software which is installed with snap) [09:56] (5th time, that's the output of snap list --all) [09:57] avih: so you have no disabled snaps? [09:57] not anymore [09:57] that's why I was thinking that you didn't put the --all in it [09:57] oh [09:57] yeah, i removed them. [09:58] to quote one of my initial comments: after i removed all the non-current snaps, it still uses 6.3G at /snap/ and 3G at /var/lib/snapd/ . needless to say that i did not request to install any of them. [09:58] (i guess i meant "non disabled") [09:59] avih: I mean the easiest is really debate if you need gnome-system-monitor and snap-store, backup the firefox data directory and purge snapd if you have that of an disk space issue [09:59] i don't need the gnome task-manager-ish, and i don't know what snap-store is [09:59] avih: type snap-store as a command and see ;) [10:00] if you like it or not [10:00] oh, it's a gui thing i see. i'm connected remotely, it refuses to open [10:00] "No manual entry for snap-store" [10:01] so what is it? some gui store thing to choose what snaps to install? if yes, i don't care about it [10:01] yeah, but I assume you ever heard of gnome-software (it's a software which lets you "shop" around to install software) [10:01] it's not only snaps, but also deb packages [10:02] i think i've heard of gnome-software, but i do all my installs either via apt or i build things myself. i don't use any gui installer [10:02] or store [10:02] maybe i used aptitude once or twice years ago, but i don't care about gui stores [10:03] which means the only software _is_ firefox, just make sure you backup ~/snap/firefox/common/.mozilla as that's your firefox profile [10:03] oh, it was moved there from ~/.firefox/ (or whatever it was before)? [10:03] (on the other hand if you remove snapd, it doesn't remove stuff from ~) [10:04] yes [10:04] it was ~/.mozilla [10:04] can i try to keep only firefox and its deps first? how do i do that? [10:04] right, previously ~/.mozilla [10:05] try to remove everything which isn't firefox? :) [10:05] you can but not 100% sure which are needed for firefox (but as I said, snapd will complain if it's needed) [10:05] (seriously? no way to tell which snaps firefox depends on?) [10:05] I do know core and core20 should be nonremovable [10:06] I assume it's core20, firefox, gnome-43-2204, gtk-common-themes [10:06] ah and bare [10:06] but remember core is not removable (even with nothing depending on it :S) [10:08] hmm.. so i removed gnome-system-monitor, it told me it "disconnects" it from some things (why does it overwrite the line as it works so i can't have the list?!), and i ended up with ~zero space freed [10:08] avih: probably because gnome-system-monitor is a snap which is very very small [10:08] just think about it, the gtk dependencies are in a different snap, which means the snap is maybe 5 megs? [10:09] nuala: wait, wouldn't it remove the deps too if nothing depends on it? [10:09] no [10:09] murmel: ^ sorrt [10:09] y [10:09] si*t [10:09] additionally, did you --purge? [10:09] h [10:09] no [10:10] that's why it keeps the snap file [10:10] just sudo snap remove gnome-sys.... [10:10] it does? [10:10] remove --purge gnome- [10:10] $ sudo snap remove --purge gnome-system-monitor [10:10] snap "gnome-system-monitor" is not installed [10:11] obvious, you removed it ;) [10:11] the snaps are stored in /var/lib/snapd/snaps [10:11] so? did it remove the file or not? [10:11] no as I said, to also remove the file, you need to use the --purge switch [10:12] ok, but now after i removed it without --purge, what can i do to also remove the file? [10:12] what do you think if i gave you the directory where the snaps are stored [10:12] i.e. how do i unf(ck it? [10:12] !language [10:12] Please avoid any language that may be considered offensive, including acronyms and obfuscation of such - also see https://wiki.ubuntu.com/IRC/Guidelines || The main channels are English only, for other languages, see https://wiki.ubuntu.com/IRC/ChannelList [10:12] i don't understand the question [10:12] it doesn't help when you "censor" it [10:13] right. unimportant i didn't understand your question [10:13] avih: make sure the file is not in that directory? otherwise delete it [10:13] which dir? /snap/ ? [10:14] read what I type? [10:14] man [10:14] ok, sec [10:15] right the snaps are stored in /var/lib/snapd/snaps [10:15] yes [10:16] i don't see it there https://0x0.st/odN0.txt [10:16] oh, interesting. I thought the snap was being kept, seems like it doesn't [10:18] ok, so back to "how to i remove verything except firefox and its deps". should i just try to remove all of them except firefox until nothing get removed anymore? [10:18] yes [10:19] but also, if that's where the snaps are, and it's ~3G for me, what's at /snaps/ ? (which is ~6.5G for me) [10:19] test [10:19] ig21: loud and clear [10:20] murmel: so what's at /snaps/ ? [10:20] /snap/ [10:22] oh, wait, so the /var/lib thing is the "source" package, and /snap/ is where it's extracted or some such? [10:22] yes [10:28] murmel: so, i ran this few times till it removed no more: (for s in $(snap list --all | tail -n +2 | awk '{print $1}'); do [ "$s" = firefox ] || sudo snap remove --purge "$s"; done) [10:29] snap list --all now prints: https://0x0.st/odNn.txt [10:29] and firefox seems broken [10:29] what is broken? [10:29] first error of several: firefox [10:29] update.go:85: cannot change mount namespace according to change mount (/var/lib/snapd/hostfs/usr/share/cups/doc-root /usr/share/cups/doc-root none bind,ro 0 0): cannot create directory "/usr/share/cups/doc-root": permission denied [10:30] iirc you said firefox depends on some gnome packages, right? but all of them now seem removed [10:30] snap seemingly didn't prevent me from removing all the gnome-* ones [10:31] yeah, I am baffled honestly [10:31] i'm lest only with core, core20, and firefox [10:31] left* [10:32] interestingly enough, it complains about cups oO [10:33] avih: as I said I'm not using snap, but here's another idea, maybe if you remove firefox snap now, and reinstall firefox snap, it will pull the dependencies it's missing [10:33] there are more, https://0x0.st/odNR.txt [10:34] yeah, so you can reinstall firefox to get the dependencies back or go full non-snap system [10:34] alkisg: yeah, i'm sure it's possible from the ppa, but i was attempting to remove all snaps except firefox and its deps [10:34] avih: "reinstall firefox snap". Not deb. [10:35] I.e. maybe the purging/removing dependencies code isn't very mature, but I doubt that the snap install firefox code wouldn't pull the missing snap dependencies [10:35] alkisg: it could fix it, but so far i've not yet started to think how to fix it. just trying to understand how it got broken [10:36] yes, i imagine it might [10:36] hope you can find the issue, I'm out [10:36] Eh, apt has almost 3 decades on its back, I'm sure you can find a lot of cases where snap isn't as mature :) [10:36] however, the worrying thins is that removing all those packages freed about only about 1.5G [10:36] of disk space [10:36] Are you counting the loopback mounts on /snap, or the source size in /lib? [10:37] df -hs [10:37] df -sh /lib or /snap? [10:37] sorry, df -h [10:37] just df -h [10:38] What's the output? [10:38] https://0x0.st/odN7.txt [10:38] Files in use will be freed after they're not in use anymore [10:39] Not sure if snap behaves properly in that regard [10:39] so /dev/sda1 has ~1.7G free and after all packages were removed and purged except 3, it has 3,2G free [10:39] Try rebooting, if you measure just the df and not the du -sh /lib... [10:39] it had 1.7G free, now it has 3.2G free [10:39] yeah, will try [10:40] Also, what's the output of this? sudo du -sh /var/* /usr/* /lib/* | sort -h | nc termbin.com 9999 [10:41] fwiw, it behaved as if "snap won't let it remove it if things depends on it" is 100% incorrect [10:42] sec, still rebooting [10:42] i think unity broke too [10:42] i don't get a desktop anymore [10:43] Did you reinstall the missing dependencies? [10:43] define "missing" [10:43] The ones that you uninstalled and made firefox complain [10:43] i tried to remove all snaps except firefox till nothing more got removed [10:43] no, i rebooted after you said the free space might show up after reboot [10:44] OK, login to vt2 then and reinstall the missing snaps [10:44] i'll ssh into it [10:44] df -h still shows 3.2G free on /dev/sda1 [10:45] For the disk usage issue, the command I mentioned above will help ^ [10:45] i'm trying to find it :) [10:45] sudo du -sh /var/* /usr/* /lib/* | sort -h | nc termbin.com 9999 [10:46] (still running) [10:46] yeah, unity desktop definitely ot broken [10:46] got* [10:46] Ah, termbin might stop processing when it takes a long time [10:47] alkisg: https://0x0.st/odqi.txt [10:47] You'd better do it in two steps: sudo du -sh /var/* /usr/* /lib/* | sort -h > /tmp/disk.log; cat /tmp/disk.log | nc termbin.com 9999 [10:47] i didn't pipe to termbin [10:47] 8.7M /var/snap [10:47] So snap is fine, and the bigger parts are 4.6G /var/log and 5.4G /usr/lib [10:47] yes, but the snaps are at /var/lib/snapd, no? [10:48] Not sure, try du -sh /var/lib/* | sort -h then [10:48] 1.4G /var/lib/snapd [10:48] not terrible [10:49] good morning, I need help [10:49] and /snap/ is 1. [10:49] 1.2G [10:49] That's a loop-mount, it doesn't count [10:50] so overall 3G instead of ~10G used by snaps, but df -h still shows 3.2G free, and it should have been ~7.7G free (6G freed by snaps) [10:50] hmm [10:51] What did you measure to see that snap was using 10G? [10:51] Judging from the snaps you had installed, I wouldn't have expected 10G [10:51] as i said, /var/lib/snapd/ was 3G, and /snap was 6.5G (but you now say it doesn't count) [10:52] Right, so from 3G you freed 1.5G [10:52] this is ****** up [10:53] so firefox got broken, unity got broken, non-snap things (unity) do depend on snaps, and and snap doesn't refuse to remove snaps which other things depends on [10:53] basically, the cake is a lie [10:54] Eh, I decided to remove snap ages ago, no need to preach at me :D [10:54] even if i install the firefox snap, surely it won't restore things which unity depends on [10:54] excepy by pure luck [10:54] I don't think unity depends on snap, but a broken snap can affect things [10:55] So you can either reinstall the dependencies and fix it, or remove it so that it doesn't affect the rest of the programs [10:55] well, unity worked, and after i removed some snaps it doesn't work. [10:55] Yeh, firefox too [10:55] Dependencies do that, removing them breaks things not only in the snap world [10:56] Don't think that snap is completely isolated and that its breakage won't affect apt [10:56] well, i got pretty straight up replies "non snap things don't depend on snap" [10:56] which was wrong, at least in some ways. ffs. [10:57] I never said that :) [10:57] i didn't say you did :) [10:57] But in any caseit should be easy to reinstall your missing snaps and restore what you had [10:57] some other people [10:57] (which did try to help, my fault for not cross checking their suggestions) [10:58] If you didn't keep your initial list, it's still there: https://0x0.st/odNK.txt [10:58] i do have the link [10:58] but i doubt reinstalling all of them would fix the broken things [10:59] the "snap remove $whatever" prints that it "disconnects" the removed snap from things, and i doubt it will "reconnect" them upon install [10:59] AFAIK it does [11:00] the other issue is that it used terminal escape sequences to rewrite the same line, so even the terminal scrollback doesn't have the list it disconnected from [11:00] snaps declare connection points and mounts and whatever they call them in their description [11:01] anyway, forgetting firefox for now, my current problem is to get a desktop. it was set to auto-login without a greeter, and now it fails to start unity, and i'm not sure how to make it show the greeter [11:01] i do have xfce4 installed [11:02] (i don't know if it would work, but it exists. greeter would be a good start) [11:02] Without knowing the snap internals, my experience with it is that removing SOME snaps make the DE fail. So either reinstall the deps, or remove snap. [11:03] how do i change the greeter config from cli to start xfce4 instead of unity? [11:03] i believe it's the default one (gdm?) [11:04] There's a lightdm.conf entry for this, I think it's user-session=xfce, or you can temporarily move aside /usr/share/xsessions/*.desktop and leave only the one you want [11:04] great, and now i get a message from the not-started unity that "desktop will suspend soon due to inactivity" [11:04] systemctl stop lightdm will kill it :D [11:09] alkisg: so i moved all of them elsewhere except xfce4.desktop, killed lightdm, started it, it showed the login dialog, username is correct, i entered the password, and it "fails to start session" [11:10] this is like bad bad [11:10] i can still use it remotely, which is my main use case anyway, but the desktops seems just broken, which sucks [11:12] i'm a fool to believe advice so quickly,, and murmel should not have talked so confidently with their advice if they're not 100% sure it's actually true. [11:16] for posterity: "snap remove foo" WILL remove foo even if other snap depend on it, and removing some snaps can break non-snap packages, like xfce4 refusing to start [11:19] alkisg: how come the space at /snap doesn't count? is it ramdrive? or some virtual things which maps into /var/lib/snapd like "zip folders" used to do on windows? [11:20] is it possible to restart a VPN connection (not stop and start it)? [11:23] i hope to enable BBR in ubuntu 20.04, i see the parameter configure is " net.ipv4.tcp_congestion_control=bbr", but my traffic is IPv6, how to enable IPV6 bbr ? [11:26] avih, /snap is just mount points, there is no actual data in it [11:27] ogra: of what? [11:27] avih, snaps are compressed, gpg signed read-only filesystem images that only get loop mounted (imagine a CDrom iso) but never unpacked ... the acual space they occupy is in /var/lib/snapd/snaps [11:28] right, so it's a virtual mount which is passthrough to extracted data from /var/lib/snapd ? [11:28] what you see in /snap is just a representation of what the upacked content would be, but it is nevr actually unpacked [11:28] right, thanks [11:28] there is no extracted data [11:28] i understand [11:28] it's fetched on demand [11:28] (well, there is, but only at runtime in ram ... for the bits actually needed by a binary) [11:29] right [11:29] i understand, yes [11:29] snaps are generally way smaller than th equivalent of binary data in debs [11:30] (and are 100% tinker proof thanks to being readonly and signed) [11:30] ok, anyway, after i removed everything i could except "firefox", lightdm fails to start a session. i do have xfce4 installed for instance, and if i run it via remote x then it starts, but in lightdm it shows "failed to start session" [11:30] everything = snaps [11:31] well, there is nothing except the snapd package that hoks into your session ... and given you still have the firefox snap, the snap daemon will/should LSO BE STILL THERE [11:31] OOPS [11:31] lightdm does show the greeter, and i can enter password and choose a DE, but it shows a blank screen instead of starting the DE [11:32] sorry, rogue capslock [11:32] thats very unlikely to be related to any snap removals [11:32] well, it did work before k remove the snaps... [11:32] i* [11:33] what exactly did you remove ... [11:33] 1st i removed all disabled snaps, which resulted in snap list --all printing this: https://0x0.st/odN0.txt [11:33] "snap list" should still show snapd, core20 and firefox [11:34] looks like you removed the snapd snap [11:34] then i followed an ill advice that to keep only firefox, i can try to remove everything except firefox and snap will refuse to remove deps of firefox. i ended up with this https://0x0.st/odNn.txt [11:35] well, this is true if you properly use "snap remove" ... [11:36] not sure what "properly" means, but i did this: (for s in $(snap list --all | tail -n +2 | awk '{print $1}'); do [ "$s" = firefox ] || sudo snap remove --purge "$s"; done) [11:36] i ran this few times till nothing more got removed, and i was left with core, core20, and firefox [11:36] well, try removing and then installing the firefox snap ... it should pull the missing bits back in [11:37] won't i lose the firefox profile if i remove it? [11:37] also, probably a "snap install snapd" first [11:38] you can use snaps backup feature and make a snapshot ... (though first re-install the snapd snap ... then take a look at "snap help save") [11:39] later you can restore the snapshot with "snap restore" (see: snap help restore) [11:39] that will back up your profile (and all other data of the package) and restore it properly [11:41] in general it helps to take a deeper look at "snap help" to familiarize with the features snaps give you [11:41] ogra: thanks. so installing snapd (how is it allowed to be removed?!) seem to improve things. desktop seem to start now. sec. still checking things [11:41] good [11:47] ogra: do you happen to know in lightdm, if the list is too long and the screen (Resolution) too small, how to view what's below the bottom of the screen at the list of DEs ? [11:47] no idea, sorry, has been ages since i used lightdm last (6y or so) [11:47]
