Thanks ashbonne, this indicates to me that 'update-grub' is not the cause of the problem for you (but may still be the issue for others). I will look into other possibilities.
As a side note, the '|' symbol (which is typically found on English keyboards on the same key as the '\' symbol) is referred to as the 'pipe' in Linux-speak. If you care to know, its job at the command line is to take the output of the command before it and 'pipe' it as input into the command after it. Therefore, in this case, 'ps ax' outputs a list of all running processes, and 'grep update-grub' searches the input for any instances of the text 'update-grub'. -- Ubuntu software center says waiting for other software managers to quit when none are open https://bugs.launchpad.net/bugs/464020 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
