I also get "ValueError: /usr/bin/python3.4 (deleted) does not exist" by starting with a Vivid cloud image, installing lxc and juju-local from the archive, and then do-release-upgrade -d to Wily. So this will happen to every Juju charm developer on upgrade, I think. No PPA required.
Separate from this I got the original: initctl: Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: Connection refused invoke-rc.d: unknown initscript, /etc/init.d/lxc not found. when I upgraded my main machine to Wily just now. In fact the initctl: Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: Connection refused was repeated all over the upgrade. I wonder if this only happens when the system was previously upgraded from an upstart-running system, and we have two bugs here? I think this should be Importance: Critical and needs to be fixed before Wily release as we don't want upgraders failing just because they were experimenting with charm development - and this reproduces entirely from the archive without any PPAs. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to lxc in Ubuntu. https://bugs.launchpad.net/bugs/1490110 Title: package lxc 1.1.3-0ubuntu1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 100 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1490110/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
