<html> <head> <meta content="text/html; charset=ISO-8859-1" http-equiv="Content-Type"> </head> <body bgcolor="#FFFFCC" text="#000000"> I have a new problem now: It no longer boots. It starts up with the splash screen (for Ubuntu Studio) and then that disappears, I get a CLI and various text outputs, and it gets as far as starting TIMidity++ but then freezes. I can still reboot and even press CTRL-ALT-F1 for a terminal, but the booting will not go any further to the login screen or anything. I can boot into Linux Mint (which I am using now) on the PC so I know that the hardware is still functioning. Any ideas what could be wrong and how to fix it? Otherwise it looks like I will have to do a fresh install. I already backed up a list of my installed packages, and my /home is on a separate partition.

I therefore used the Update Manager, went to 11.04, then to 11.10. But I cannot get any further. When I try to run the Update Manager, nothing happens. I tried from a terminal and got the following: ~$ update-manager Traceback (most recent call last): File "/usr/bin/update-manager", line 26, in <module> from gi.repository import Gtk File "/usr/lib/python2.7/dist-packages/gi/__init__.py", line 23, in <module> from ._gi import _API, Repository ImportError: /usr/lib/python2.7/dist-packages/gi/_gi.so: undefined symbol: g_callable_info_skip_return Is this a known bug, or is it just something simple that can be fixed easily?
