Re: clean Linux install while keeping the same packages installed as before

by Gregory Avedissian

For debian-based systems, you can use 'dpkg --get-selections' and 'dpkg --set-selections' to reproduce a set of installed packages. You can expect to run into errors if you are using this to go to the next release, because some packages will be missing or replaced with a different named package.

Re: clean Linux install while keeping the same packages installed as before

by Joshua Stone

I'm hoping it'll get easier to back up and upgrade OS installs with the advances in containerized runtimes like flatpak and podman/distrobox, and immutable distros like Silverblue. For example, I can back up application installs from: /var/lib/flatpak Optionally I can store just the list of names and re-install them later: $ flatpak list --system --app --columns=application --ostree-verbose > apps.txt $ cat apps.txt com.bitwig.BitwigStudio com.discordapp.Discord com.github.k4zmu2a.spacecadetpinball com.github.tchx84.Flatseal com.github.wwmm.easyeffects com.mojang.Minecraft com.obsproject.Studio com.spotify.Client io.mgba.mGBA md.obsidian.Obsidian org.chromium.Chromium org.gimp.GIMP .. .. org.kde.krita org.keepassxc.KeePassXC org.libreoffice.LibreOffice org.mozilla.firefox org.signal.Signal org.videolan.VLC org.x.Warpinator us.zoom.Zoom And -- more importantly -- user data can be backed up from: ~/.var/app Silverblue also seems to handle updates/upgrades very well as none of the updates apply to the running system. It also makes a clear distinction between OS and application by relying on flatpaks and toolbox as the primary means of application management. This is definitely a significant change from the familiar package model, but it's one that I think has merit. I'm excited to see these technologies mature and become more integral to modern Linux distros! - Josh On Fri, Jan 14, 2022 at 9:08 AM Chuck Anderson via WLUG <wlug(a)lists.wlug.org> wrote: > I'm more familiar with Fedora where I do something like this.

Sorry -- are we supposed to know what the WLUG youtube account-name is? How it is to be found, etc? I looked around a bit. I looked on youtube, I looked on wlug.org. Maybe (probably?)

It was a really fun meeting, and I enjoyed meeting Kalman and learning even more about emacs (as I write this using emacs...) and the power it provides.

clean Linux install while keeping the same packages installed as before

by Chuck Anderson

I'm more familiar with Fedora where I do something like this. It should be possible to do the same in Ubuntu with the appropriate apt-get commands. 1. List all packages with their names only (no versions) on both the old system and newly installed system, assuming the new system is booted and the old system is mounted at /mnt/oldroot. Alternatively, do the first command (without the --root parameter) when booted to the old version and save the file somewhere: rpm -qa --qf='%{name}\n' --root=/mnt/oldroot | sort -u > old-pkglist.txt rpm -qa --qf='%{name}\n' | sort -u > new-pkglist.txt 2. Compare the files and save that output: diff -b -U0 {old,new}-pkglist.txt > old-new-diff.txt grep ^- old-new-diff.txt | cut -c2- > missing-from-new.txt grep ^+ old-new-diff.txt | cut -c2- > only-in-new.txt 3. Now go through the list and install what you want. I usually do this step manually rather than using some automated script, since there are many changes I don't necessarily want, such as shared libraries. All I really care about is applications/commands/utilities. I go through the lists, reading the diff in one window and installing stuff I want in another: dnf install a b c d ... and/or this which installs a package and all of its subpackages except development and debug subpackages. This is great when a package has a bunch of plugins I want: dnf --exclude='*devel*' --exclude='*debug*' install foo-\* ... Or you could curate the list, e.g. edit missing-from-new.txt keeping only the lines you care about, then automatically install everything that is in the curated list: cat missing-from-new-curated.txt | xargs dnf -y install > >> On Thu, Jan 13, 2022 at 3:47 PM gmcaplan--- via WLUG > >> <wlug(a)lists.wlug.org> wrote: > >> > >> I was hoping to attend, but it looks like I will not be able to. > >> I hope it will be recorded because I, too, would like to learn about > >> emacs. > >> Also, I have two questions: > >> 1.

Re: Reminder: Virtual Meeting today at 7PM Topic: Emacs awesomeness.

by Chris Thompson

Hello! I'd like to offer a couple notes regarding your upgrade. `apt list --list` may list more than what you've installed explicitly. It will include the packages installed by default in the system (/var/log/installer/initial-status.gz) as well as all the dependencies of packages you've installed. Anyway - that makes for a useful complete list, certainly, but you can generally work from a much smaller list. I think the list you may want comes from `apt-mark showmanual` to list packages you've specifically installed. All this said, https://askubuntu.com/questions/1383951/apt-mark-showmanual-shows-almost-al… seems to indicate that results based on manual installation flags can be problematic before 20.04, so YMMV (though you can exclude from your list based on the initial-status file above as well). While you can do a bash loop and install the packages that way, you can also list a whole bunch on a single run, e.g. `apt install x y z q`. If you are adding >1000 packages, you're likely to run into a limitation doing it that way, but just mentioning - it'd be a little bit quicker (being able to skip identifying packages already installed via others, and running triggers fewer times, etc). Not that it matters all that much, but if you did come up with a list of just 50-100 you need, it's be a reasonable approach. Note that there are changes between the packages in different versions of the OS. Some packages may no longer be available, having been abandoned, and others may be substituted with different packages and so on. While these suggestions will get you close, it may not quite be perfect. If you did opt for an upgrade instead (which works very well in my experience) such changes will often be pointed out to you and/or accommodated for automatically. Finally, don't forget to check for any additional sources you may have added in `/etc/apt/sources*` Regards, Chris On 1/13/22 17:59, gmcaplan--- via WLUG wrote: > Thank you.
