Uploaded the fix to all series (after testing the fix on vivid). Note that the problem is mostly visible on series which don't have procps-instance.conf as those that do will not fail on upgrade (but sysctl itself still fails).
To test the fix, it's best to run: cat /etc/sysctl.d/*.conf /etc/sysctl.conf | sysctl -e -p - && echo pass ** Changed in: procps (Ubuntu Precise) Assignee: (unassigned) => Stéphane Graber (stgraber) ** Changed in: procps (Ubuntu Utopic) Assignee: (unassigned) => Stéphane Graber (stgraber) ** Changed in: procps (Ubuntu Vivid) Assignee: (unassigned) => Stéphane Graber (stgraber) ** Changed in: procps (Ubuntu Trusty) Assignee: (unassigned) => Stéphane Graber (stgraber) ** Changed in: procps (Ubuntu Precise) Importance: Undecided => High ** Changed in: procps (Ubuntu Trusty) Status: New => In Progress ** Changed in: procps (Ubuntu Utopic) Status: New => In Progress ** Changed in: procps (Ubuntu Trusty) Importance: Undecided => High ** Changed in: procps (Ubuntu Utopic) Importance: Undecided => High ** Changed in: procps (Ubuntu Vivid) Importance: Undecided => High ** Changed in: procps (Ubuntu Precise) Status: New => In Progress ** Changed in: procps (Ubuntu Vivid) Status: Confirmed => Fix Committed -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to procps in Ubuntu. https://bugs.launchpad.net/bugs/1419554 Title: Can't upgrade procps in LXC 1.1 Status in procps package in Ubuntu: Fix Committed Status in procps source package in Precise: In Progress Status in procps source package in Trusty: In Progress Status in procps source package in Utopic: In Progress Status in procps source package in Vivid: Fix Committed Bug description: == SRU == Rationale: sysctl now fails with current LXC as files which shouldn't be written to in containers are read-only. A previous fix applied to the EACCESS case as returned by apparmor. Text case: start procps Regression potential: All EROFS write failures will now be ignored (an error is still logged) but I can't think of a case where that'd be a bad thing. Original bug report: LXC 1.1 on vivid has started giving privileged containers a read-only /sys, which prevents Ubuntu's procps Upstart job from starting. This isn't normally too problematic, except that the weekend's procps SRU's postinst tries to start the job and causes the upgrade to fail. Disabling the procps postinst makes apt usable again.
