[Bug 994152] Re: do-release-upgrade says it can not run the upgrade

[Richard Cheung]

Yes, do-release-upgrade work again.

My ubuntu was installed with virtual machine mode with cd-rom iso and
python-apt was not installed before.

Description: Python interface to libapt-pkg
 The apt_pkg Python interface will provide full access to the internal
 libapt-pkg structures allowing Python programs to easily perform a
 variety of functions, such as:
 .
  - Access to the APT configuration system
  - Access to the APT package information database
  - Parsing of Debian package control files, and other files with a
    similar structure
 .
 The included 'aptsources' Python interface provides an abstraction of
 the sources.list configuration on the repository and the distro level.
Original-Maintainer: APT Development Team <deity at lists.debian.org>
Python-Version: 2.7

Why I found this solution was because another virtual machine prompt me
about the missing of python-apt.

The strange part was that both virtual machine are installed with VM
mode (ubuntu 12.10)

Title:
  do-release-upgrade says it can not run the upgrade

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

Bug description:
  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]

  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.
