Thank you Robert Chapman for your reply,
I don't have any more that problem, (only freezes
sometimes) the solution seemed to work, and is similar
to the one that I found.
How could we inform other users about the solution/fix?
As I monitor these last 2 weeks the update manager
they keep posting
Dear xmac - I am sorry , I did not realize you were waiting for a fix -
The following worked for me. I am a complete novice but have been able
to sort out all my problems by searching all the forums that google has
given me when I search for my problems.It can take a while finding the
answers but
after waiting about 2 weeks for any solution to be proposed
I tried on my own the following
I searched the 60 files in the directory /var/lib/apt/lists which had among them
the following 4 files:
archive.canonical.com_ubuntu_dists_jaunty_partner_binary-i386_Packages
the strage thing was that after deleting the 4 files out of 60 files in the
directory /var/lib/apt/lists
they remained 49 !!!
and now they are again 60 files in that directory !!!
but, the update manager doesn't work :-(
