Hi everyone,

Similarly, we have been observing do_image tasks fail sporadically in CI/CD 
pipelines for a while.
You can see a few examples below:

INFO - | E: 10mount: umount: 
/run/schroot/mount/isar-builder-31888f6e-6228-4bc8-9570-dd4d69ad25ba-367048-331187ba-b359-48ad-91f4-2962f4bdf32b: 
target is busy.

Do you have any information regarding the root cause?

Thanks,
