[SOLVED] Partial update broke my pacman; cannot fix with chroot from live ISO

What happened:

1. Ran
Code: [Select]
sudo pacman -Syu
.

2. Update somehow crashed the terminal that was running the update command and kicked me out of my session. It is therefore a partial upgrade.

3. Tried to restart. At first, it booted upto the runit initialisation screen and then shut down. Next time, it started doing the usual
Code: [Select]
vmlinuz-linux missing
stuff.

4. Booted into an artix live ISO. Decrypted the partition. Mounted the drive. artix-chrooted into the mounted drive. Tried to run
Code: [Select]
pacman -Syu
.

5. Got
Code: [Select]
pacman: error while loading shared libraries: /usr/lib/libcrypto.so.3: file too short
.

What I figured about the issue:

1. Read <this>. Found that
Code: [Select]
# pacstrap -K /mnt --overwrite base libgcrypt libgpg-error systemd-libs
is supposed to be run to fix the issue. But realised that the
Code: [Select]
systemd-libs
part is not applicable to me.

2. Read <this>. Found that pacman-static may help recover from a partial install. Could not figure out where and how pacman-static must be installed i.e. on the mounted drive or live-iso or some specific place in my mounted iso using makepkg.

My questions:

1. Which of the two methods above are appropriate for my situation? pacstrap -K.... or pacman-static?

2. How do I execute either of the solutions?

The below post is far more effective.

About the only useful thing this post contained is that pacstrap is renamed to basestrap on Artix.

From a live ISO, mount the broken / partition to /mnt. Issue
Code: [Select]
# pacman --sysroot /mnt -Sy pacman-static
Then you can artix-chroot into /mnt and resume the update with pacman-static -Su

I tried implementing nous' suggestion. I got this message when I tried to install pacman-static:

Code: [Select]
error: failed to synchronize all databases (unable to lock database)

Found this post on archwiki.

Need suggestion on how to execute
Code: [Select]
rm /var/lib/pacman/db.lck
Do I mount with artix-chroot and do that or just change the path in the command and execute it?

It should be ok to run rm /mnt/var/lib/pacman/db.lck

There is no db.lck in /mnt/var/lib/pacman. Any other location it could be stored at?

if you are chrooted

maybe
/var/lib/pacman/db.lck


do a find :)

find /  -iname "db.lck" -print

I chroot-ed into /mnt and issued rm /var/lib/pacman/db.lck. It seemingly deleted the file but when I exited the chroot environment to run pacman --sysroot /mnt -Sy pacman-static, I got the same error of "error while loading libraries".

I then issued sudo rm /mnt/var/lib/pacman/db.lck from the live ISO environment and it let me run pacman --sysroot /mnt -Sy pacman-static.

The output of that was:

I then chroot-ed into /mnt again and issued pacman-static -Syu. It gave me the following error:

Code: [Select]
error while loading shared libraries: /usr/lib/libgdbm.so.6: file too short

Then I exited the chroot envrionment and issued sudo pacman --sysroot /mnt -Syu. I got this error:

Code: [Select]
error: could not open file /mnt/var/lib/pacman/local/nvidia-utils-570.133.07-1/desc: No such file or directory

warning: could not fully load metadata for package nvidia-utils-570.133.07-1
error: failed to prepare transaction (invalid or corrupted package)

Now I do not know how to proceed with fixing the issue.

----

I also tried this and this. Both gave me the same error as above.

I also tried going into the chroot and issuing just pacman -Su and got the same error.

Errors occurred, no packages were upgraded.

I searched a little and found that this could be the reason behind the issue. Because I noticed that the clock on my live ISO is not correct.

I changed the date of my live ISO using the date command with sudo. Then issued pacman --sysroot /mnt -Syyuu --overwrite='*' again. This time, I got many like these initially:

Code: [Select]
usr/bin/ldconfig: File /usr/lib/libabsl_scoped_set_env.so is empty, not checked

followed by this:

error: problem occurred while upgrading signal-desktop
error: could not commit transaction
error: failed to commit transaction (transaction aborted)
Errors occurred, no packages were upgraded.
warning: could not remove lock file /mnt/var/lib/pacman/db.lck

I found this while searching for the solution. Should I, as advised in the link, wait to update again or do something else?

honestly, this is sounding too hard.  I've had this problem and hard to do this.  And I didn't have instructions.  Artoo told me to use the base and chroot it and I just removed all the pacman cache and reinstalled all of pacman. 

In the end, it is easiest to just move your data off the system and reinstall.

@Anaximenes You can add a '--ignore signal-desktop' directive for signal-desktop (or comma-separated list for every package that throws such errors), but in the end, it might be better to follow @mrbrklyn 's  advice and reinstall. This situation shouldn't pose a problem to a user well-familiarized with pacman, but experience comes with time and system breakages.

Re: Partial update broke my pacman; cannot fix with chroot from live ISO

The only reason I was trying for so long was because I had made too many minute changes to my set-up to make my production workflow easy. It would take me more time to do the set-up once again (mostly because I forgot most of what I did) than recover the PC.

But I have come to a point where recovery does not seem possible because after yesterday's partial update via external pacman , I think the LUKS has been messed with. I cannot mount the drive anymore because cryptsetup does not recognise it as a valid LUKS partition. Luckily I recovered some of my important data before this point so not all is lost.

Thanks to everyone that helped me get this far. :)

those settings should mostly be in your home directory which is why we have home directories.

Either way, a full on pacman reinstall needs to be done which is not as hard as it sounds.  Just remove the pacman cache and it will have to rebuild it.  As for LUKS, I am not expert in disk encryption but I don't see how a pacman update can kill your crypto keys.  FWIW, maybe I missed it but I didn't see you say you had the drive encrypted, but you had access to the drive from the recovery disk.  So why can't the crypto keys be backed up?

You should not be suffering a catastrophic lose because of a bad update.

@mrbrklyn I had made many changes in my /etc or /usr/share or other such places which I cannot recollect. A few that I could recollect, like hosts file and xorg.conf.d files, I backed-up. The others, I have forgotten so do not know where to look for them.

But nonetheless thanks for everything. :)
