Dear Maintainer,
alsa-utils show a warning during upgrade from 1.2.5.1-1 to 1.2.6-1:
Unpacking alsa-utils (1.2.6-1) over (1.2.5.1-1) ...
dpkg: warning: unable to delete old directory '/usr/lib/systemd/system/sound.target.wants': Directory not empty
But it seems files in this directory are already from alsa-utils :
$ ls -la /usr/lib/systemd/system/sound.target.wants
total 40
drwxr-xr-x 2 root root 4096 Jan 23 10:24 .
drwxr-xr-x 27 root root 36864 Jan 23 10:25 ..
lrwxrwxrwx 1 root root 23 Jan 12 10:42 alsa-restore.service -> ../alsa-restore.service
lrwxrwxrwx 1 root root 21 Jan 12 10:42 alsa-state.service -> ../alsa-state.service
$ dpkg -S /lib/systemd/system/sound.target.wants/{alsa-restore.service,alsa-state.service}
alsa-utils: /lib/systemd/system/sound.target.wants/alsa-restore.service
alsa-utils: /lib/systemd/system/sound.target.wants/alsa-state.service
As a workaround I did rm this dir and reinsall alsa-utils. sound.target.wants state after reinstall hasn't change
Regards,
Nicolas
