Updating packages with Pamac fails

[Vivian]

Hello everyone,

a few months ago I couldn’t update packages with Pamac anymore. I tried a bunch of tutorials to fix this. Among others I tried what is marked as solution at "error: GPGME error: No data" when I'm trying to update a couple of times. At my last attempt I left out the step of restoring the original Pacman configuration (thus the security checks are still disabled) and I disabled the AUR in the pamac settings.
For a few days I thought I had fixed the problem, but when I try to update the packages in Pamac, the refreshing of the database hangs at 22 percent and I get the error “database synchronization failed”.
I tried to update the packages with Pacman in the terminal and that gave a GPGME error.
I saw at Fehler „Fehler: GPGME-Fehler: Keine Daten. Fehler: Alle Datenbanken konnten nicht synchronisiert werden (unerwarteter Fehler)“ (GELÖST) that I should enter rm -R /var/lib/pacman/sync and then sudo pacman -Syu, and that worked insofar as the GPGME error disappeared and I could update the packages that way, but Pamac still gives the same database synchronization error message every time I try it.
How could I solve this problem?

but Pamac still gives the same database synchronization error message every time I try it.

pamac has its own place for the databases:

/var/tmp/pamac/dbs/sync

Usually a force refresh should solve it:

pamac update --force-refresh

Same goes for pacman:

sudo pacman -Syyu

[root tip] [How To] Mitigate and prevent GPGME error when syncing your system

You are getting a message when syncing your system error: GPGME error: No data error: failed to synchronize all databases (invalid or corrupted database (PGP signature)) Before you continue [SOLVED] Error updating system (error: GPGME error: No data) / Newbie Corner / Arch Linux Forums Pacman troubleshooting - Manjaro Pacman looking for database signature files Also see this pacman bugreport from 2015 - which was closed as not a bug but a matter of configuration.

Then make sure you fully update your system, but do it from a tty while completely logged out of the GUI environment.

sudo pacman-mirrors -f && sudo pacman -Fy && sudo pacman -Syyu
pamac checkupdates --force-refresh

Be sure to let the above commands finish. Do not interrupt the update process.

Thank you!
I did what the TL,DR section of the tutorial you linked said.
Than I logged out of my account from the GUI. Is that what you meant by "completely logged out of the GUI environment?
I entered a tty and entered the commands you gave. The second command either did nothing or did what it did very quickly without feedback, so I entered that one a few times.
Then I shut down the computer and rebooted.

Since then Pamac seems to work as I expect, even with the AUR enabled.

Should I change anything (back) about the Pacman configuration, or is it secure as it is now?

Yes, exactly.

If it didn’t do anything, then there were no updates to your AUR packages.

It is fine now. You had a corrupted package database, and now it’s fixed again.
