[Bug 1396951] Re: webbrowser-app’s autopilot tests fail on otto: access to /dev/shm is denied

 

It’s likely that LP virtual builders for x86 are on trusty (or an older
ubuntu release anyway), this /dev/shm issue started appearing in vivid,
which would explain why we’re not seeing it in PPA builds.

Of course when LP builders are upgraded to vivid(+n), builds will start
failing. If we can devise an acceptable solution for the vivid chroots
used by CI, then we should be able to apply it to LP as well.

Title:
  webbrowser-app’s autopilot tests fail on otto: access to /dev/shm is
  denied

Status in Automated UI testing on Hardware:

Status in webbrowser-app package in Ubuntu:

Bug description:
  The CI job that runs autopilot tests for webbrowser-app on otto (desktop) has been consistently failing since the switch to vivid.
  The error seen in the log is the following:

  /var/local/autopilot/autopilot.log: [1127/102329:ERROR:shared_memory_posix.cc(231)] Creating shared memory in /dev/shm/.org.chromium.Chromium.UAVbQt failed: Permission denied
  /var/local/autopilot/autopilot.log: [1127/102329:ERROR:shared_memory_posix.cc(234)] Unable to access(W_OK|X_OK) /dev/shm: Permission denied
  /var/local/autopilot/autopilot.log: [1127/102329:FATAL:shared_memory_posix.cc(236)] This is frequently caused by incorrect permissions on /dev/shm.  Try 'sudo chmod 1777 /dev/shm' to fix.

  At a first glance it looks to me like the problem is in the otto setup
  itself.
