[Bug 564053] Re: do-release-upgrade --sandbox fails after cancelling

[Rolf Leggewie]

I ran into the same issue today, having bind-mounted
/var/cache/apt/archives to a temporary storage for the upgrade.  During
day-to-day-operation my /var partition is limited to 2G.  Why is bind-
mounting an issue here?

Title:
  do-release-upgrade --sandbox fails after cancelling

Status in “update-manager” package in Ubuntu:
  Triaged

Bug description:
  Binary package hint: update-manager

  after bug 562394 was reported fix, I decided to test it.

  I ran:
  $ sudo do-release-upgrade -d --sandbox

  It promted me with:
  Continue running under SSH? 

  I said "No".  Then, started a screen session, and ran again.

  The second run dies with:
  Sandbox setup failed 

  It was not possible to create the sandbox environment.

  
  Preparing the upgrade failed 

  Preparing the system for the upgrade failed. Please report this as a 
  bug against the 'update-manager' package and include the files in 
  /var/log/dist-upgrade/ in the bug report.

  /var/log/dist-upgrade/main.log has:
     2010-04-15 17:34:00,915 WARNING mountpoint /var/cache/apt/archives submount of systemdir

  If I do 'sudo umount /var/cache/apt/archives', it will continue past
  this state.

  Note, after the cancel there are still several aufs mounts and such
  left around, but they dont seem to prevent re-running as the
  /var/cache/apt/archives mount did.
