news 28 Posted April 6, 2011 In 11.04 and later versions, the desktop CD installer (ubiquity) presents an option to upgrade Ubuntu if it finds a single copy on the system. This functionality is not exactly equal in operation to upgrade-manager, nor does it share much code with that application. Such an upgrade will first make a backup of apt's state, including repacked debs (using dpkg-repack) for any packages that it cannot find a source for. Following this, it will delete all non-user and non-local files on the existing partitions. This is roughly everything but /usr/local, /var/local, /usr/src, and /home. It will then install Ubuntu over top of the partially-cleared directory structure and install the packages referenced in the apt state backup. When triaging upgrade bugs, please make sure they're targeted to and have logs for the correct package. If the user upgrades via the option in the desktop CD installer, change the package to ubiquity and have the user run `sudo apport-collect $bug_number`. Thanks, Evan -- Share this post Link to post
