For your informations, the origin of the pb is that dpkg failed becaused I had installed scipy from source a while ago (and forgot that). The presence of real files in /usr/lib/python instead of symlink (the way things are now done in debian/ubuntu) made dpkg fail.
So the real problem is, as stated in the modified title, when a pb occur during the upgrade, the update-manager application just stops. The embedded terminal do not shown anything after that point. Actually, I've noticed that the file descriptor (a pipe I guess) for this embedded terminal is then closed, so the running dpkg just hang waiting for data to be written in this pipe (I've straced it). I had no other choice than killing it, and finishing the installation with a "apt-get install --configure" in a terminal. -- KDE frontend crashes Qvector inser run out of index https://bugs.launchpad.net/bugs/116188 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
