[11:39] adding a desktop is no problem, removing one can be interesting.. [12:07] Hi all === thopiekar_ is now known as thopiekar [16:49] what kind of Kubuntu have you installed ? (re @IrcsomeBot: I have installed kubuntu. Now while logging in, along with kde, gnome and gnome wayland are also showing) [19:17] Hello :). I'm wanting to install Kubuntu 22.04 on my 2nd hard disk, and am stuck at the first step. There is a check-box labelled: "Configure secureboot, enter the same password twice.....". My laptop supports UEFI & Secureboot and I'd like to enable that feature, but I don't know how to proceed. My first question is - which password? I [19:17] don't understand what is needed here or what it does. Any help would be greatly appreciated. [19:26] Guest21: the idea there is that you set a password for the first time, which is then stored by your mainboard / bios, this is part of secure boot initialization [19:28] tomreyn - thanks for the reply, do I need to enter this password on each boot? [19:28] a lot can go wrong with 'secure boot', it complicates matters and it doesn't provide a whole lot of guarantees. so a lot of people actually decide against using it [19:29] you'll need to enter this password whenever you want to change secureboot settings, including when entirely disabling secure boot. [19:31] Ah, OK - so I don't really need it. The only downside I guess is that I'd need to enter UEFI to disable secureboot every time I wanted to boot Kubuntu? (I also have a Win10 installation that uses secureboot) [19:39] most operating systems don't actually require secure boot, so maybe you'll want to keep it off generally. but if you want to run a multi boot system then maybe leaving it enabled with kubuntu can actually be the better choice. [19:41] Thanks for your time, much appreciated. I'll go ahead and experiment in the hope that it doesn't mess up my Windows disk (I have backups just in case). Cheers :). === Lord_of_Life_ is now known as Lord_of_Life [20:31] https://packages.ubuntu.com/jammy/linux-headers-generic [20:31] Anyone knows what is the actual kernel version behind this [20:47] IrcsomeBot: ksenchy: it says 5.15.0.25.27 in your own link [20:48] and you can also see that it depends on the https://packages.ubuntu.com/jammy/linux-headers-5.15.0-25-generic package [21:53] hi there [22:02] I have Kubuntu 21.10 (impish) on my desktop. In order to try the software Able2Extract Professional, a PDF editor, I downloaded its deb package from the official site, but it requires, among others, the version 1.71.0 of the package libboost-filesystem, instead of the current 1.74.0. In fact, it needs also libboost-regex1.71.0, [22:02] libboost-thread1.71.0, which are not available for impish. They are available for hirsute and focal, indeed. Is there a port for impish? Is it reliable to try and download the debs for those releases and install them under impish? [22:39] No suggestions? [22:45] More generically, is it possible/sensible to try and install older versions of a given deb package? If so, how and which issues might arise? [22:49] @orca33 you are now experience the joys of interim releases :) [22:51] Sorry if this is old new to you, but just in case: The trouble is that the 6-month release cadence is too fast for many third-party developers. Instead, they focus their energy on LTS releases and build for them. [22:53] orca33: there's no snap / appimage / flatpack thing for that application? [22:53] I see: if I were with focal, I would then be ok... [22:53] you could try building one of those, they can contain their own userland, with different library versions [22:54] This appears to be the case for Able2Extract. If you are able to install it on Impish it will *probably* work just fine, since the updated libboost-filesystem isn't significantly greater. However, if there is a breaking change, you might be out of luck without the work that @cbreak is detailing. [22:54] cbreak, not AFAIK [22:54] you could also run the thing inside docker or lxc [22:54] @orca33 You could always install focal in a VM and use it there ... [22:55] lxc is cheaper than a full vm :) [22:55] even if you use kvm [22:55] Sure @cbreak. Any similar sort of environment. [22:55] I run a firefox inside a 20.04 lxc on my 21.10 kubuntu [22:56] so gui programs kind of work (there are some issues with screen resolution) [22:57] I have never tried to build a snap , appimage or flatpack for that matter. Neither used lxc; and vm some eons ago... [22:58] mmikowski what does do you mean: "If you are able to install it on Impish..."? How? [22:59] @orca33 download the deb, and then `sudo apt install ./` [23:03] As simple as that? The worst might happen is the command not working and then I might simply issue: sudo apt --fix-broken install or sudo apt purge ; right? [23:03] @orca33 fwiw, snaps run in a docker-like environment (lxc) and pull in their own requirements like above. [23:04] @orca33 simple as that. [23:04] @orca33 if it doesn't work, sudo apt purge . [23:04] Notice, it may also be subtly broken, which can be the worst kind of broken sometimes. [23:05] The sudo apt --fixbroken install probably won't do the trick. [23:06] boost should install its libs with version number in the name, so they shouldn't collide [23:08] Right @cbreak. However, if the earlier versions of libboost libs are not available in impish and it doesn't allow for later lib versions in it's control file... :P [23:09] I mean if the package doesn't allow for later libboost version... [23:12] that's more a fact of you not having the old package available [23:12] but what I mean is that IF you got hand of it, it shouldn't collide with the current version [23:12] probably... :P [23:12] ah, I got it @cbreak. You mean also installing the dependencies by hand from the prior repo? [23:13] cbreak and mmikowski nice observations. In fact, I also installed libpoco*70 packages to try and resolve the error, without success. So I guess I will download libboost-[filesystem,regex,thread]1.71.0 from hirsute and see what i get... [23:13] Maybe, if they allow concurrent versions. Not a problem with the lib, but could be an issue with the packaging. [23:14] Kernels do the right thing there, but lib packages often do not IME. [23:14] https://packages.ubuntu.com/focal/amd64/libboost-regex1.71.0/download [23:16] Right. But that will likely want to downgrade the installed libboost-*, which could cause all sorts of issues. In that case, lxc or similar as you suggested earlier would seem much safer. [23:17] I think they're independent [23:17] the packages have the version number in the name [23:17] they're effectively different packages [23:17] boost is a c++ lib without ABI stability, I think they kind of have to do it that way [23:17] Yeah, that's a great point. Similar to kernel images. So the should be able to live together. [23:17] just like kernels, not designed to be forward or backwards compatible [23:18] (still, I'd go the lxc route, since I know how to do it :) [23:18] well... or at least I think I can look up how I did it again... [23:20] @cbreak it seems like your suggestion with these libboost-x.x.x packages should be safe, since they won't interfere with anything and likely won't be used elsewhere. And rolling back is as easy as purging the packages. [23:21] I haven't used lxc before, but will look into it! [23:23] I think I used something like https://blog.simos.info/running-x11-software-in-lxd-containers/ [23:24] @orca33 did you get the suggestion from @cbreak? [23:24] It looks like you are on the right path. [23:24] @cbreak thanks for the link. I will add it to my thing-to-do ticket. [23:24] (I think if someone upgrades from 20.04 to 21.10, those old packages could still stick around, so it should be fine) [23:25] Sorry for the silly question: which exact link shoud I use to download, e.g,. libboost-regex1.71.0? I tried cbreak's one above from focal, but did not manage :-( [23:26] what was the problem? [23:26] I think Ubuntu could keep some of those older libs around longer... [23:27] curl -OL --url http://mirrors.kernel.org/ubuntu/pool/universe/b/boost1.71/libboost-regex1.71.0_1.71.0-6ubuntu6_amd64.deb seems to work [23:28] of course, I'm assuming here that you're running amd64 [23:29] cbreak The curl command worked. [23:33] To double check: I have downloaded the 3 libbost-*1.71.0*.deb packages from focal and now I should dpkg -i each one of them and afterwards try and install the Able2Extract package; right? [23:33] I'd zfs snap first :P [23:33] (but it is probably ok) [23:34] cbreak didn´t get this zfs snap stuff... [23:35] you're not running zfs then, so you can ignore it [23:36] After sudo dpkg -i libboost-filesystem1.71.0_1.71.0-6ubuntu6_amd6.deb , I got the following error: dpkg-deb: error: 'libboost-filesystem1.71.0_1.71.0-6ubuntu6_amd6.deb' is not a Debian format archive [23:37] @orca33 you can do `sudo apt install ./libboost*` if you put them alll in a single directory. [23:37] also: dpkg-deb --control subprocess returned error exit status 2 [23:37] Um, that deb package looks wrong - the name on the end should be _amd64.deb. Maybe just a cut-n-paste error? [23:38] mmikowski sure [23:39] The suggestion for putting all the packages in a subdir and using apt makes sorting dependencies easier. Otherwise, you may need to step through dpkg installs one dependency at a time. Apt will sort all that for you. [23:40] As for the file not being debian, that can occur when one downloads files using 'save link as' and accidentally saves the html instead of the package. [23:43] what does `file` on the archive say? [23:43] I am redownloading the debs [23:43] I've not tried to install, but file says "libboost-regex1.71.0_1.71.0-6ubuntu6_amd64.deb: Debian binary package (format 2.0), with control.tar.xz, data compression xz" [23:47] sudo apt install ./libboost* gives: E: Invalid archive signature, E: Internal error, could not locate member control.tar{.zst,.lz4,.gz,.xz,.bz2,.lzma,}, E: Could not read meta data from /home/orca/Dropbox/resources/Able2ExtractPro/libboost-filesystem1.71.0_1.71.0-6ubuntu6_amd64.deb, E: The package lists or status file could not be parsed or opened. [23:56] I tried again with dpkg -i and for the libboost-regex*, it had dependency problems, demanding the libciu66 deb package, whereas the other 2 libboost* showed error exit status 2 [23:57] libciu66 -> libicu66 [23:59] I guess we should call it a day... Thank you very much for all your effort, guys!
