Undoing/removing pacman vendor change and removing pacman packages

English Multimedia

Hi

I added the pacman essential repo, but only some of the packages from it so I could troubleshoot some playback issues I was having on youtube, I no longer have playback issues.
Could someone tell me how to undo the pacman vendor change, and also tell me how to properly remove the pacman packages+dependencies I installed. Below is a summary of my commands

zypper ar -cfp 90 https://ftp.gwdg.de/pub/linux/misc/packman/suse/openSUSE_Leap_15.2/Essentials](https://ftp.gwdg.de/pub/linux/misc/packman/suse/openSUSE_Leap_15.2/Essentials) packman-essentials

sudo zypper install --from packman-essentials --force libavcodec56 libavcodec57 libavcodec58 libavformat56 libavformat57 libavformat58 libavdevice56 libavdevice57

The following 14 NEW packages are going to be installed: libavdevice57 libavdevice58 libavfilter7 libavresample4 libbs2b0 libpostproc55 librtmp1 libSDL2-2_0-0 libswscale5 libvidstab1_1 libvo-amrwbenc0 libx264-160 libx265-192 libxvidcore4

The following 12 packages are going to be upgraded:
 libavcodec57 libavcodec58 libavfilter6 libavformat57 libavformat58 libavresample3 libavutil55 libavutil56 libpostproc54 libswresample2 libswresample3 libswscale4

The following 12 packages are going to change vendor:
 libavcodec57    openSUSE -> http://packman.links2linux.de
 libavcodec58    openSUSE -> http://packman.links2linux.de
 libavfilter6    openSUSE -> http://packman.links2linux.de
 libavformat57   openSUSE -> http://packman.links2linux.de
 libavformat58   openSUSE -> http://packman.links2linux.de
 libavresample3  openSUSE -> http://packman.links2linux.de

 libswresample3  openSUSE -> http://packman.links2linux.de
 libswscale4     openSUSE -> http://packman.links2linux.de


12 packages to upgrade, 14 new, 12  to change vendor.

I presume you won’t delete all packages from repo packman-essentials, but only the unneeded ones. Try:

3400G:~ # zypper search -is --repo packman |grep ^i+
i+ | ffmpeg-4                   | package | 4.3.1-8.3                      | x86_64 | packman

no I want to remove(dleete) all the packages installed from packman-essentials, I dont need them at all in this PC, I want this PC to be back to the same approved SUSE packages prior to installing pakman-essentials

You could try:

(1) disable or remove the packman repo;

(2) use

zypper dup --allow-vendor-change

which should switch everything back to the main repos;

(3) use

zypper packages --orphaned

to list any remaining packages from packman, which you could then delete as desired.

You may get some conflicts. And you could do a “–dry-run” with the “zypper dup” to just inspect what will happen.

Very good, I was wondering if someone noticed what I thought was missing in earlier posts…
When you “zypper dup” that’s not sufficient unless you undo the command that set the packman repository in the beginning… You also have to add "–from repository_id " where the repository id is some identifier related to the OSS repository(can be anything that uniquely identifies the repository) and in the provided example I’ve highlighted in** lime green** .

Note that it’s standard package management that it’s not guaranteed uninstalling packages will return your system to the status before the packages were installed… sometimes files will be left behind which if you really need to remove would have to be removed manually.
The alternative method to guarantee a return your system to previous status with absolutely no crud left behind is to use snapper and BTRFS snapshots to roll back to a date and time before you added those packages (and other changes will be rolled back as well).

Hello,

The solution provided by @nrickert is the right one.
I want only to add that: when you have “regular” openSUSE repos and “another” repo, to revert all the packages to “regular” repo you have to disable (remove) “another” repo and a simply “zypper dup” is enough. It will revert all the packages to “regular” repo. You do not need “zypper dup --allow-vendor-change” or “zypper dup --from regular_repo”.

Below is the output from following @nrickert. First step I did was disable the pacman repo through yast, then

zypper dup --allow-vendor-change
