Hi,

For some reason I cannot reproduce this issue locally. I have tried both
on amdahl as well as a local arm64 system via sbuild. Here the logs of
the latter attempt:
https://people.debian.org/~ema/user-session-migration_arm64.build

The sbuild environment should match pretty closly what we have on the
buildds: sbuild 0.89.3+deb13u4 on trixie using the unshare backend.

Perhaps someone more familiar with the package can suggest how to try
and reproduce?

  ema

It now also failed on loong64:
https://buildd.debian.org/status/fetch.php?pkg=user-session-migration&arch=loong64&ver=0.5.1%2Bb1&stamp=1776919552&raw=0.
So it looks like this issue is not architecture specific.

Cheers

I am unable to reproduce the build failure locally with sbuild+unshare
targetting unstable.
Additionally, the build succeeds in Salsa CI and in Launchpad (with an
Ubuntu PPA).

I have hesitated to do an upload to Unstable because I didn't want the
build to show as failed on all architectures.

Marco, do you have any ideas on how to fix this or how you want to
workaround the issue?

Thank you,
Jeremy Bícha

Hi Jeremy,

I also tried it myself, and indeed I get no failure at all.

Couldn't be that a false-negative? Can we retry and see?

https://buildd.debian.org/status/logs.php?pkg=user-session-migration&ver=0.5.1%2Bb2&arch=arm64
the buildds tried 7 times so far, and didn't succeed.

BR,
Chris

Hi,

I've been able to reproduce this issue (on a loongson machine).

The test depends on timing instead of actually checking whether the previous actions were completed.

https://salsa.debian.org/debian-ayatana-team/user-session-migration/-/blob/main/tests/test_migration.py?ref_type=heads#L231
```
time.sleep(1)  # ensure that the directory is touched after the first run
```

If I comment out this line, I have a reproducer.

Proposal: set the delay to a higher value, perhaps 5 or 10?

-> MR pending at https://salsa.debian.org/debian-ayatana-team/user-session-migration/-/merge_requests/7

With kind regards,
Roland Clobus
