[Bug 994152] Re: do-release-upgrade: Can not run the upgrade, 'No such file or directory'.

[mcfedr]

I have just installed python-apt and now it works.

I am also running on a virtual distribution, python-apt wasn't installed
before.

Maybe python-apt needs to be a dependancy of ubuntu-release-upgrader-
core

Title:
  do-release-upgrade: Can not run the upgrade, 'No such file or
  directory'.

Status in “ubuntu-release-upgrader” package in Ubuntu:
  Confirmed

Bug description:
  I am also having this problem.

  $ sudo do-release-upgrade
  Checking for a new Ubuntu release
  Get:1 Upgrade tool signature [198 B]
  Get:2 Upgrade tool [1,206 kB]
  Fetched 1,206 kB in 0s (0 B/s)
  authenticate 'raring.tar.gz' against 'raring.tar.gz.gpg'
  extracting 'raring.tar.gz'
  Can not run the upgrade
  The error message is 'No such file or directory'.

  * Original Description

  [The originally reported error “/tmp is mounted noexec” is not a bug.]

  Whenever attempting to run do-release-upgrade I get an error:
  $ do-release-upgrade
  Checking for a new ubuntu release
  Get:1 Upgrade tool signature [198 B]
  Get:2 Upgrade tool [1550 kB]
  Fetched 1550 kB in 0s (0 B/s)
  authenticate 'precise.tar.gz' against 'precise.tar.gz.gpg'
  extracting 'precise.tar.gz'
  Can not run the upgrade
  This usually is caused by a system where /tmp is mounted noexec. Please remount without noexec and run the upgrade again.

  I have checked /tmp
  $ ls -l / |grep tmp
  drwxrwxrwt  15 root root  360 2012-05-03 13:00 tmp

  which is obviously not mounted noexec.

  [This is not the proper way to check noexec, use ‘mount’.]
