[00:00] /path/to/mounthpoint is for instance: /dev/sda? [00:00] no, that's a device node. a mount point is where it's mounted to, e.g. / or /home or /var or /boot [00:05] oh, so is fstrim like defrag on windows tomreyn ? [00:08] frad: no. it's to tell ssd's and nvme's which parts of the file system are currently unallocated (not containing data that is still needed) and thus enables the disk firmware to reallocate its physical blocks in a better way, [00:09] frad: if you've stored data on such a device for a while without running TRIM or discard against it (and it didn't happen automatically either) then they *can* get slow. [00:10] im ambivalent, because I have no backup and I wouldn't want to irreparably delete something I need [00:10] on current ubuntu releases, there's a systemd unit + timer to run weekly TRIMs against file systems supporting it. [00:11] oh, so this is done automatically once a week? [00:11] if you have no backups then your data must be irrelevant. [00:11] maybe I don't have money for new ssds [00:11] it should ususally happen on a regular schedule, yes [00:12] backups dont have to be on ssds [00:12] but spindrives are loud... [00:13] they don't have to be in the same computer. [00:13] i'll stop making excuses [00:13] and they'Re not really noisy [00:13] :) [00:13] wait if Im real sensitive? [00:13] * mason leads a goat out on-stage and steps back to see what happens. [00:18] ! discard [00:18] !discard [00:18] .discard [00:18] !trim [00:18] Many Solid State Drives support TRIM, which allows the drive to do garbage collection and improves performance. Ubuntu 14.04 activates it by default. For older versions, see http://askubuntu.com/a/19480 for information on activating it. [00:18] oh [00:18] lol [00:21] unlike trim, dicsard is a file system mount option for file systems which support it. some file systems can do both discard and trim, others can only use one of those. and discard can cause problems or larger devices so trim should be preferred where possible. [00:38] how do I tune2fs a luks encrypted nvme? [00:38] first I have to decrypt... [00:38] the nvme unit being the unit I am now using [00:39] sorry, encrypted nand drive [00:39] just to be sure you're not mixing up tools: we didn't discuss tune2fs so far. [00:40] no, this I knew from somebody else [00:40] tune2fs is a utility to manipulate ext file systems. you can use it against and unmounted, and some of its functionality also against mounted ext file systems. [00:41] oops, strike the first "and" there. [00:41] I only want to set reserved blocks to 0.5% [00:42] as long as the crypto layer is open, i.e. you have an unencrypted device node which directly points to a file system, you can run tune2fs against it. [00:43] the default setup on ubuntu would be crypto layer -> lvm PV -> lvm VG -> file system, though. [00:43] the default setup on ubuntu would be crypto layer -> lvm PV / VG -> lvm LV -> file system, though. << correction [00:48] tomreyn, thanks but I must leave now. See you around and thank you! === zbenjamin_ is now known as zbenjamin === gabkdlly_ is now known as gabkdlly [02:43] hello i use ubuntu 20.04 but there is no python [02:43] what’s wrong? [02:44] !info python3 focal | futureRich [02:44] futureRich: python3 (source: python3-defaults): interactive high-level object-oriented language (default python3 version). In component main, is important. Version 3.8.2-0ubuntu2 (focal), package size 46 kB, installed size 189 kB [02:45] python instead of python3? [02:45] :( [02:46] !info python focal [02:46] Package python does not exist in focal [02:47] futureRich: you can apt-install either python-is-python3 or python-is-python2 depending upon which set of scripts you want to break :) [02:47] futureRich: I suggest instead using pythoh2 for your programs written in python2 and using python3 for your programs written in python3 [02:47] futureRich: just pretend the 'python' name doesn't exist and fix things as necessary [02:48] i will try it [02:53] how can i install pip for python? help me plz [02:54] futureRich: ask apt-file [02:54] there is no pip [02:54] futureRich: sure there is [02:54] apt-file that is, not apt-cache [02:55] futureRich: you know about the 'universe' repo? [02:55] and ubuntu ships with a neat thing that if you type a command that doesn't exist, it'll suggest what to install to get it: https://paste.ubuntu.com/p/ps3kkXhv4g/ [02:56] apt search pip —> no answer [02:56] futureRich: well nobody said to use apt search pip... [02:56] sarnold: does it do that without universe enabled? [02:56] then matsaman ? [02:56] sarnold: for pip3 in particular, that is [02:56] futureRich: apt-file [02:56] apt-file? [02:56] what is it? [02:57] it's a package and executable [02:57] it tells you what packages provide executables, for example [02:57] anyway you want python3-pip from the 'universe' repo [02:57] give a yell if you need help with that [02:57] matsaman: heh, good quesiton; I've always assumed command-not-found didn't need universe.. [02:58] matsaman: there is pthon2-pip? [02:58] futureRich: python-pip is for 2 [02:58] if you're making something new I wouldn't use python2, but python3 instead [02:59] as python2 is end of life [02:59] matsaman: there is no python-pip [03:00] futureRich: there is, in the 'universe' repo [03:00] universe repo? [03:00] how can i see it? [03:00] futureRich: sudo add-apt-repository universe [03:01] futureRich: and then sudo apt-get update [03:01] thanks [03:01] Hello everyone! I have a laptop with hybrid graphic card set up (integrated intel, discrete nvidia). With my Ubunutu 18.04, I was simply using the discrete nvidia as the primary gfx. [03:02] Recently, I learnt about Nvidia optimus [03:02] https://wiki.archlinux.org/index.php/NVIDIA_Optimus [03:02] I am about to upgrade my Ubuntu to 20.04. [03:03] Does it provide any support for Prime? [03:05] Simply put, I want to use the integrated gfx as my primary graphic card and use nvidia gfx only for certain tasks. [03:06] monojamoon|: yes [03:07] matsaman: any tricks in its setup? [03:07] I think the process is to install intel drivers (should happen automatically), install proprietary nvidia driver from repo and then install prime? [03:08] monojamoon|: there are a few different ways you can do it [03:08] what you just described is basically one way [03:08] https://askubuntu.com/questions/661922/how-am-i-supposed-to-use-nvidia-prime [03:10] Ah! Thanks a lot! [03:14] when ubuntu 18.04 will be supported till? [03:19] i don’t know why they remove python? :( [03:19] unlike 18.04 [03:20] futureRich: python2 reached end of life on january 1, 2020. Upstream isn't going to provide any more fixes of any kind for it. [03:21] futureRich: it won't be removed from Ubuntu for a while, however [03:21] futureRich: canonical is going to try to support python2 in precise, trusty, xenial, and bionic, for as long as we can, for as many issues as we can. it makes no sense at all for us to release a *new* distribution with python2 when it would release without any upstream support on the first day [03:21] Finally! Python3/Python2 was like a divorce where the couple still share the same house. [03:21] but there is some program that is made by someone :( [03:21] futureRich: what program? [03:22] futureRich: you can run 18.04 in a VM or LXD instance [03:22] rfcat [03:22] futureRich: this? https://github.com/atlas0fd00m/rfcat [03:22] matsaman: yea correct [03:25] futureRich: looks like they'll have it sorted pretty soon: https://github.com/atlas0fd00m/rfcat/pull/71 [03:25] futureRich: the version from that PR might even work now, even if it doesn't pass the author's museter [03:25] muster* [03:27] matsaman: then i must wait it? [03:27] futureRich: you can follow that PR and it might be ready soon, or you can try building it from that PR right now [03:27] if it works it works [03:28] building/running, whichever is required [03:28] thanks [03:30] futureRich: same as this, which is a little easier to clone/download: https://github.com/PlantDaddy/rfcat/tree/python3-compatibility [03:31] oh great this is code for python3 ? [03:31] matsaman: ? [03:32] futureRich: that is my understanding [03:32] he's been porting rfcat to py3 [03:32] thanks :) [03:32] i will try it [03:32] the PR says it builds, and the only reason the upstream maintainer hasn't merged is ... arguably small things, like print statements [03:35] matsaman: guy don’t fix it [03:38] matsaman: using ubuntu 18.04 is good idea instead of 20.04? [03:38] 18.04 is end? [03:39] 18 is supported till 2023 at least [03:39] then can i go to 18? [03:39] if you want [03:40] some people call me dude? [03:42] if i use 18.04? [03:44] anyway where can i install 18 version? matsaman help me plz [03:44] nah I don't think so [03:44] thanks [03:44] I would probably find a way to use rfcat on 20.04, myself [03:44] but sticking with an older version that makes your life easier for a little while is perfectly sane, IMO [03:44] i will use 20.04 in 2023 [03:44] especially an older version that remains in support [03:45] where can i download 18 version? help me matsaman ? [03:45] futureRich: well, actually [03:45] futureRich: first you should try and install 'python2' from 'universe' in 20 [03:46] matsaman: but python is python2 in 18 version but python2 is python in 20.04 version [03:47] help where can i download 18 version? help me matsaman ? [03:47] futureRich: yeah it's not really a problem if it's called 'python2' [03:48] then i can’t install pip [03:48] how can i install pip then? [03:49] futureRich: https://linuxize.com/post/how-to-install-pip-on-ubuntu-20.04/#installing-pip-for-python-2 [03:50] matsaman: thanks i will try it [03:50] :) [03:50] if i failed then i will go to 18 version [03:50] :) [03:51] sounds like a plan === PowerTower_121 is now known as PowerTower_120 [04:59] matsaman: i have mistake with ‘apt install python’ instead of apt install python3-pip, then i have 2 python2? [05:01] matsaman: busy? [05:30] <_tej_> Hi, I am unable to receive pings (or ssh into my PC) from other machines on the LAN. I am using a fresh install of Ubuntu 20.04. Google search didn't' help much. Could someone please help me resolve the issue? [05:44] Hello -- I just started using JWM over gnome and I'm very impressed with how nice it is [05:44] really happy about its keybindings, and very light too in terms of resources. [06:02] Hi, can someone give me the command to fstrim both my /home drive and all mounted drives? [06:06] moonfmdesire: fstrim --all? [06:06] p0a, Just that? [06:06] try it with --dry-run to see if it does what you wanted [06:07] p0a, What does dry run do? [06:07] moonfmdesire: it doesn't modify anything [06:08] p0a, I want it to clean up all my drives [06:08] --dry-run ensures that you don't actually do anything before you decide to do it [06:08] and --all will clean up your mounted filesystems [06:08] p0a, Will the -a option also handle the drives mounted? Like I have sdd connected via usb 3 [06:08] p0a, Ahh okay [06:08] why don't you try it with --dry-run and see what it does [06:09] ... [06:09] I'm telling you that --dry-run will only show you what happens, it won't actually do it [06:10] p0a, Okay, please give me the full command because the command line won't do anything [06:10] p0a, It just says unrecognized option [06:11] fstrim --dry-run --all [06:12] p0a, fstrim: unrecognized option '--dry-run' [06:13] moonfmdesire: what's your fstrim --version? [06:14] p0a, fstrim from util-linux 2.31.1 [06:16] moonfmdesire: that version doesn't have the feature [06:17] p0a, Like a version [06:18] p0a, Well, I ran the command -a and it did not complain [06:18] p0a, So I guess it did the job [06:19] I believe you need root to run fstrim [06:19] if you run it with --all --verbose you can see exactly what it does, I think --verbose is default but I am not sure so just add it there [06:19] moonfmdesire: 2.34 has --dry-run if you want that feature. [06:20] p0a, how do i install it? [06:20] moonfmdesire: you need to update `util-linux' [06:21] moonfmdesire: apt update && apt upgrade util-linux [06:21] p0a, My install says I have the latest, if I upgrade, will it cause problems? [06:21] what version of ubuntu are you using? [06:22] p0a, 18.04 [06:22] moonfmdesire: One option, which may or may not make sense for you, is to just upgrade to Ubuntu 20.04. [06:22] moonfmdesire: I don't think it's important to upgrade util-linux. Leave it as is. [06:23] Jordan_U, It will harm me. I run proprietary graphics drivers, that will break it. [06:23] p0a, I just want to trim my drives [06:23] p0a, I agree with you. [06:25] p0a, Thanks for your help. [06:26] moonfmdesire: You probably have successfully done that. If you want to know how much space has been trimmed from all of your drives you can just run "sudo fstrim -a --verbose", which will tell you how many blocks have been trimmed from each filesystem. It doesn't actually trim them again if the blocks haven't been written do (and then erased) since the last time you trimmed. [06:26] Jordan_U, Ahh, okay, thanks! [06:27] Jordan_U, I am moving files from smaller ssd's to a bigger one to simplify a project I am working on [06:27] right now [06:27] but will run it again [06:27] moonfmdesire: You're welcome. [07:35] Greetings, say does someone know where to setup network options for apt get? I have a a problem with timeouts and nothing loading till them. Ideally i want reduce the timeout time but increase the retries to very high. [07:52] Elw3: [07:53] Elw3: ... Can you pastebin some example apt output that demonstrates the problem you're seeing? Are you on a particularly poor / unreliable internet connection? [07:54] It stalls, what do you expect from that? [07:55] Elw3: Is it "apt update" or "apt install" (/upgrade) that is causing more problems? Does the operation eventually complete after it times out and retries? [07:58] booth, but i only care on install atm. The problem is that it doesnt retry fast and often enough. It looses connection, then waits minutes, then retries, and eventually gives up. [07:59] Elw3: Do you have a particularly poor internet connection? [07:59] Yes very. [08:01] Elw3: https://wiki.debian.org/AptConfiguration (specifically "Acquire::http::Timeout "2";: sets the timeout for HTTP downloads [08:03] guys i have a question please [08:04] Elw3: Also, what version of Ubuntu are you using and do you get stalls with all applications / protocols or only some? [08:04] CoDeAmRo: Ask away :) [08:05] Well my netspeed is 7kbs, so everything internet stalls. But interestingly this doesnt happen if i for example boot to ubuntu 10 (which is still on my disk) [08:05] is there away to connect my ubuntu screean on my smart tv wireless same with windows 10? [08:06] CoDeAmRo: To be clear, you want to have whatever is on your screen in Ubuntu show up on your TV, is that correct? [08:07] yes [08:07] screen mirroring [08:08] to view my ubuntu os on my tv [08:09] CodeLyoko: Do you know what protocols your smart TV supports? Does it support "casting" as if it were a chromecast for example? [08:10] miracast and intel widi [08:15] CodeLyoko: https://github.com/albfan/miraclecast seems to be an option, but it's also not available in Ubuntu's default repositories and looks to be not very easy to use. [08:16] I checked on Ubuntu Studio and it seems like the fswatch issue is there too. The flag --exclude ".*" on Ubuntu 20.04 with Xfce and Xubuntu 20.04 just excludes everything and can't be overwritten by --include "xyz"... [08:16] Xubuntu was on a VM and Ubuntu Studio was on a separate computer as the main OS. [08:17] So, maybe now is the time for the logical next question: What are good alternatives to fswatch? [08:17] I found github/facebook/watchman, but it seems one has to build from source (which didn't work for me). [08:19] I have 2 users on a machine , one is able to access the shared nfs permission that has perms 777 , the other can't , i can't figure out what is the issue. Any ideas? [08:20] Jordan_U, it appears setting the timeout this way worked. but now whats the line for retries? I wonder if there is a file containing all possible flags. This cluttering options at all places is painfully annoying. [08:21] Elw3: man apt.conf [08:22] Oh i did not know you can use man on files that way. Interesting, thanks. [08:23] Elw3: If you want to see all of your current settings (this doesn't include settings that *can* be set in a configuration file but currently aren't) you can run "apt-config dump" or presumably just "cat /etc/apt/apt.conf.*" . [08:23] c/lastlog Elw3 [08:23] hrmmm, hitting c a lot lately [08:25] Yes i did that, but the missing *can* is a showstopper for that dump. [08:26] zmagii: inotify , or for certain things fanotify seem to be the main options. If you want a utilities you can use from a shell then use inotify-tools. If you're trying to add features to a program written in a certain language, that programming language probably has its own nice bindings for inotify / fanotify. [08:33] i execute this command : apt-get install python, then i will be install python? i use 20.04 ubuntu with python2 preinstalled [08:33] ? [08:34] Jordan_U: Thanks, I'll have a look. === strobelight is now known as Guest14187 [08:34] futureRich, Ubuntu's python command is 'python3' [08:34] 'python' doesn't exist [08:34] stephanie: so i installed it with ‘apt-get install python' === strobelight_ is now known as strobelight [08:35] Python3 comes preinstalled [08:35] You shouldn't be using Python 2 [08:35] It's a security risk [08:35] stop [08:35] i asked somethin [08:35] g [08:36] futureRich, sudo apt install python2.7 [08:36] there is python2 and python3 now but i installed python with ‘apt-get install python’. then there is 2 python2? [08:36] futureRich, Yes there is multiple names for the same thing [08:36] multiple name for samething [08:36] there is only 1 python2 then? [08:37] Some people may have used upgrade and not a clean install and have 2.7, 2.6 and 2.5 on their system [08:37] Different versions of python have different features, for example something might have been depreciated in a newer python such as 2.7 and so the user installs 2.6 [08:38] but version is same —> python —version python2 --version [08:38] Yes [08:38] That's good [08:38] Use python3 for python 3 [08:38] Not python [08:38] then it is just different name? [08:38] for python2? [08:39] Python and python2 link to python2 [08:39] Python3 links to python3 [08:39] ah [08:39] what is this command : apt-get install python? [08:39] stephanie: ? [08:39] futureRich, installs python2 [08:40] but 20.04 have python 2 already [08:40] before apt-get install python [08:40] No [08:40] it doesn't [08:40] then? [08:40] 20.04 has python3 [08:40] no [08:40] Yes 20.04 has python3 [08:40] 20.04 have python2 [08:41] if you have python2 then you've upgraded from 19.10 or earlier [08:41] 20.04 have python2 and python3 [08:41] 20.04 clean installed has python3 only [08:41] lol [08:41] stephanie@stephanie-Latitude-E6330:~$ python2 [08:41] Command 'python2' not found, but can be installed with: [08:41] sudo apt install python2 [08:41] stephanie@stephanie-Latitude-E6330:~$ [08:42] strange [08:42] my computer have python2 preinstalled [08:42] on 20.04 [08:42] Not strange, you've either upgraded or installed something that needs python2 [08:42] Maybe your drivers need it [08:43] ok anyway thanks [08:45] mac vs ubuntu, which is easier to use for noobs? [08:45] should be mac! Otherwise they would be out of business. [08:46] Free OS that is easy to use out of the box! Oh boy! Bye bye windows, bye bye mac! [08:47] Eh, i find its getting harder to ise since 2012... [08:47] *use [08:53] futureRich: That depends a lot on what types of things you do with your computer, what you're used to using (even "noobs" have more lived experience with computers than they might realize, and with that some expectations for how things will look/work). There's no general answer that can be given to that question. [08:56] Everyone should feel right at home using Ubuntu [08:56] And if they don't they're irrelevent [09:05] *sigh* now my joypad isnt working anymore. 3 buttons do nothing in jstest. [09:10] Its a ps3 pad, one would assume they are widely spread enough so that their functioning is secure. [09:30] if one of my administrators accidentally did an 'apt-get upgrade' instead of an 'apt-get update' and upgrading all the packages broke applications that can't yet use the lastest version is there a way to downgrade to where they were before upgrade without a backup? [09:33] That raises the question where to get the old packages from. [09:33] would be nice if the package manager had the ability to backup the old packages before upgrade [09:34] not everyone has the ability to take a complete system snapshot or backup before upgrades [09:35] If you never clean the apt cache they are still there. You can force a version too, but be warned, this will likely just fuck everything up. [09:35] i mean the whole idea would be to provide a user friendly way to rollback without fucking everything up [09:36] i believe this is a valid problem [09:36] Indeed. [09:37] uidnull: Please watch your language in this channel. Was this an upgrade to a new release of Ubuntu, or just updates within a given Ubuntu release? If the latter, what applications broke from what updates? [09:37] Jordan_U: why are you singling me out when i wasn't even the one that started with it first [09:38] uidnull: Because I didn't see Elw3's swearing until you meantioned it. They shouldn't swear here either. [09:39] is that in the channel rules? [09:39] Whups. [09:39] Thats just how i speak actually. [09:39] Jordan_U: what authority do you have to dictate how we speak here? [09:39] uidnull: Yes, it is: https://wiki.ubuntu.com/IRC/Guidelines [09:40] shut it uidnull , this is for technical help for a reason. Cluttering makes support hard. [09:40] Elw3: you're the one that set the example [09:41] you're both retarded [09:41] uidnull: That is not acceptable language or behavior toward others in this channel. [09:42] It did not occur to me that swearing exists. I am rizon too, no single line there would acceptable here. [09:42] +be [09:43] I claim its all typos. [10:18] i'm stuck trying to upgrade: "Please install all available updates for your release before upgrading." [10:20] get this: https://gist.github.com/tbbooher/c225338c011836bc4dd8336499da32c2 [10:32] bonhoeffer: try apt-cache policy mongodb-server [10:34] thanks [10:34] that just reports status? === hendry1 is now known as hendry [10:56] bonhoeffer: this reports which apt sources provide a package named like this, which of them is currently installed, and which of them would be chosen for an upgrade based on your configured apt repository priorities and apt preferences. [10:56] ah -- thanks [10:56] (and i haven't seen the actual output on your system since it seems to have since been removed) [10:57] the output can become stale, too, it's based on when you last ran apt update to update the apt cache. [11:17] Hello. I have HP ProBook 455 G6. I downloaded the LTS .iso and booted it. It first loads Ubuntu & HP logo, but after a few minutes away only HP logo remains, and nothing to interact with. What to do? [11:22] felixi: you fail to mention how you booted this ISO, does your computer have a DVD+/- R drive or? [11:24] felixi: try a different version / edition and a different method of creating boot media [11:25] tatertots: i don't have an optical drive; I can only boot from usb [11:26] or memory card (if it is possible to boot from sd-card), but i don't have one rn [11:28] felixi: have you ever booted anything successfully? [11:28] I've tried an earlier version also, alas no luck. I tried 18.something before but no luck there either. No I haven't booted linux succesfully. I have tried manjaro and mint too [11:29] how did you create the bootable installer / live usb stick? [11:29] with balenaEtcher [11:29] is this ubuntu 20.04 desktop then? [11:29] yes [11:29] 'Morning folks [11:29] hey BluesKaj [11:30] are you on windows? [11:30] atm, yes [11:30] hey felixi [11:30] felixi: personally if this fails to boot i'd look into bios updates [11:30] hey tomreyn [11:31] felixi: you can also try http://www.chrysocome.net/dd [11:31] Hello, I installed Ubuntu 18.04 on a clean LVM disk, everything is inside the LVM even the /boot. After adding another Physical Disk to the LVM the system didn't boot [11:31] balena etcher should have worked [11:31] tomreyn: okay, I am not familiar with it [11:32] i'm only partially familiar with it, but so far it always worked for me. [11:33] felixi: bios updates can be relevant since this is an amd mobile platform which is somewhat new and i think it had some problems in the beginning. [11:33] sure, i'll look into those [11:33] tomreyn: as soon as the ubuntu logo shows up [11:34] can't you press F-something to show the messages instead? [11:34] it'd indicate where it gets stuck [11:35] p0a: you could hold down shift or keep hitting escape to bring up grub, and edit the grub menu options, passing different options to the linux kernel [11:35] !bootlog [11:35] To get a more verbose log of the boot process, remove "quiet" and "splash" from the kernel boot parameters and add "debug systemd.log_level=info". For info on editing kernel boot parameters, see https://wiki.ubuntu.com/Kernel/KernelBootParameters [11:36] but i'd start with the bios update. [11:36] tomreyn: yes, thanks, that's what I was trying to suggest. [11:37] spoonsearch: what's a 'clean LVM disk'? do you mean an LVM2 logical volume? a single one? [11:39] I have 2x960GB SSDs, sda and sdb. I did a clean install of Ubuntu 18.04 with LVM on whole sda. [11:41] Later I added sdb to extend the overall size of the root file system and rebooted. But the reboot failed with this error - grub error: disk 'lvid/...' not found. Entering rescue mode.. [11:41] i see. so you installed to sda with every file system stored on LVM2 logical volumes backed by the sda PV. [11:41] @tomreyn: Yes [11:41] and later you added sdb as a secondary PV to the same VG? [11:42] tomreyn: Yes, I added sdb as a secondary PV to the same VG to extend the overall filesystem size [11:42] hi, is there a way to setup livecd without nfs root for a pxe environment [11:42] and then you extended the LV containing the root file system and the root file system itself. [11:42] i want to mimick a livecd boot [11:43] tomreyn: Yes, exactly [11:43] spoonsearch: did you check that the LV ID and file system UUID remained the same after you extended those? [11:45] Yes, I did check matched the IDs and it didn't match [11:47] . [11:47] spoonsearch: well that would have hinted that the reboot would fail ;) [11:49] spoonsearch: so you need to run update-grub to update the grub configuration as well as update-initramfs -u -k $(uname -r) to update the initramfs with the new IDs. [11:49] tomreyn However, I repeated the entire process again (clean reinstall, etc.) but this time I did `grub-install /dev/sda` and `grub-update` and now it reboots perfectly [11:49] spoonsearch: so there's not actually any problem you're trying to solve now? [11:50] tomreyn Do I have to repeat the grub commands everytime I add, remove or resise the LVs? [11:51] yes, the UUID differs for changed partitions [11:51] Also what does this command do `update-initramfs -u -k $(uname -r)`? I didn't use this command still the system was able to reboot [11:52] @oerh [11:52] oerheks Thanks, now I understand [11:54] spoonsearch: "to update the initramfs with the new IDs" - if it wasn't needed then i guess the initramfs had already been updated or nothing in there refers to block device layers using their IDs (but rather device nodes - which did not change). [11:55] tomreyn: Also one last thing, is it safe to but everything including the /boot inside LVM? I researched about it across the web but people are fighting about it [11:56] According to my understanding if grub2 is used than it is okay, wanted some expert opinion on it. [11:58] spoonsearch: depends on how you boot,. it wouldn't work with uefi booting, there you'll need the uefi system partition to be a separate top level partition on some gpt partitioned disk. [11:59] also, with bios booting off gpt with the grub bootloader you'd need a bios-grub gpt partition [12:01] I have checked my system is BIOS not UEFI, so I should be safe [12:04] tomreyn: I just noticed, `fdisk -l` shows sda Disklabel type: dos, where as sdb Disklabel type: gpt, it isn't unusual or cause any problems? [12:07] spoonsearch: it's not unusual. whether it's going to cause problems depends on how you'll use it. [12:08] Okay, thank you for help. Have a nice day :] [12:09] you, too, spoonsearch [12:17] Whose bright idea was it to make apt stop accepting regex altogether? [12:17]
