Public bug reported: Since the update from snapd 2.17.1ubuntu1 to snapd 2.20.1ubuntu1 that landed in xenial-updates on 2017-01-05, a (private) snap I use that speaks to the soundcard no longer can do so. I now get errors of the type:
ALSA lib conf.c:3759:(snd_config_update_r) Cannot access file /usr/share/alsa/alsa.conf I see that there is an alsa slot now, but my snap (provided by a third party) does not provide an alsa plug, so there appears to be no workaround. I understand why you'd want to add an alsa slot and disable access to ALSA by default in an update. I'm not against this in principle, but if this change is to land in Xenial automatically, it seems to me that there needs to be a migration path and mention in the changelog. The changelog does say "interfaces: add alsa" but makes no mention of the ensuing expected breakage. Downgrading just the snapd package to 2.17.1ubuntu1 works around the problem. ** Affects: snapd (Ubuntu) Importance: Undecided Status: New ** Tags: regression-update -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1656289 Title: [Regression] 2.20.1ubuntu1 breaks snaps that use ALSA To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/snapd/+bug/1656289/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
