[Bug 739599] Re: update-manager crashed with AssertionError in saveDistUpgrade()

[Graham Lucking]

This is a 12.04 that was converted from an 11.10 back in November. It is
modified to be my daily working install.

I update it daily. The last update being very early morning on Monday
19th March. The first thing I did when the desktop loaded was to run
Update Manager. The message I know get from Update manager is: software
index is broken. It is impossible to install or remove any software.
Please use the package manager "Synaptic" or run "sudo apt-get install-f
in a terminal to fix this issue at first.

The strange thing is that I also have a default 12.04 Beta 1 install on
another partition. I had just booted into that install and updated it
without any problems.

It occurs to me that the two 12.04 installs may have different mirrors.
The 11.10 converted 12.04 has datahop uk as the server. The default
12.04 will have the server put in place by the install. I will check.
