** Description changed: When the sources.list is rewritten it can happen that only parts are updated and vital bits like "deb http://$unknown_mirror/ubuntu breezy main" are commented out. This leads to random error messages like the ones below. After the sources.list rewrite and the apt-get update the upgrader should check if there are new candidate versions for various packages (apt, libc6) to heuristicly detect invalid rewrites. + + The new aptsources has a concept of distro related sources. Perhaps we + can reuse it here. I am attempting to perform an upgrade of my i386 breezy install to dapper beta. I have set up the apt proxy by placing the following in /etc/apt/apt.conf.d/04proxy: Acquire::http::Proxy "http://username:[EMAIL PROTECTED]:8080"; Steps: 1. run sudo update-manager -d 2. Click the Upgrade button 3. Click the Upgrade button on the release notes window 4. The Upgrading Ubuntu window shows and then reports the following when it reaches the "Downloading and installing the upgrades" step: Could not calculate the upgrade An unresolvable problem occured while calculating the upgrade.
