Pamac 9.2 cannot run upgrade of AUR packages

After upgrade of the system during which pamac has been upgraded to 9.2.0-1 I cannot run the upgrade of the AUR packages anymore. The whole process stops at Preparing phase after I hit the Apply button for the list of transactions (packages) to be upgrade. I have found an error in the journalctl:

pamac-manager[3285]: transaction_interface_daemon.vala:290: answer_ask_edit_build_files: Timeout was reached

So even when I hit the Apply button, the window stays stuck for some time, maybe 10-15 seconds, then disappears and then everything stays frozen, until I kill it. So it seems that in the sub-dialog to accept the list of packages to be upgraded, when I just hit Apply, the program doesn't do what it is supposed to. Any idea?

See if the following bug applies... :arrow_down:

It's typically a crash of pamac-daemon.
If you want to help debugging please install gdb then run in a terminal:

sudo gdb pamac-daemon

Then launch Pamac as usual and try to upgrade the AUR package.
If pamac-daemon crashes please give the output of the terminal and execute in the same terminal:



And also give the output.

I see that you have pushed out an update to the pamac today. I have done the following:

  • I checked my BuildDirectory, it was /tmp plus I had an old version of pamac.conf
  • I saw that there was a new version of pamac.conf.pacnew in /etc
  • I removed my version of pamac.conf and replaced it with the pacnew version (it has the /var/tmp BuildDirectory)
  • finally I updated the pamac version from 9.2.0-1 to 9.2.0-1-1
  • I configured pamac according to my preferences (as it was before)

Now all works fine. Thanks for your help.

Fine :ok_hand:

No, not me. I'm not on the team. :stuck_out_tongue:

I also can't upgrade AUR packages since last update, but the chosen solutionhere didn't work for me.

So I followed your instructions and ran those commands.
What happens, is that I launched the software update window, then I accepted to build, but it gets stucks indifenitely to "Checking inter-conflicts..."

Here's what the gdb daemon spits out:

(gdb) run

And then it stays there stuck.

So I killed Pamac GUI then proceeded to interrupt in the terminal with CTRL+C and ran backtrace:

Thread 1 "pamac-daemon" received signal SIGINT, Interrupt.

What can I do more to get my updates working again?

PS, for completeness, here's my /etc/pamac.conf:

### Pamac configuration file

## When removing a package, also remove those dependencies
## that are not required by other packages (recurse option):

## How often to check for updates, value in hours (0 to disable):
RefreshPeriod = 6

## When there are no updates available, hide the tray icon:

## When applying updates, enable packages downgrade:

## Allow Pamac to search and install packages from AUR:

## When AUR support is enabled check for updates from AUR:

## When check updates from AUR support is enabled check for vcs updates:

## AUR build directory:
BuildDirectory = /var/tmp

## Number of versions of each package to keep in the cache:
KeepNumPackages = 2

## Remove only the versions of uninstalled packages when clean cache:

## Download updates in background

## Maximum Parallel Downloads
MaxParallelDownloads = 4



I did modify my pacman and pamac conf files regarding the new versions, did restart the pamac-daemon systemd unit and then everything worked again.
Thanks for the tip.
