Try this:

Be sure you have a network connection active

Open a terminal by pressing ctrl+alt+t
if doesn't work press ctrl+alt+f1 and made login with your user and password, then type:

sudo dpkg --configure -a
sudo apt-get -f install
sudo apt-get -f upgrade
sudo apt-get -f dist-upgrade
sudo apt-get autoremove
sudo apt-get clean
sudo apt-get update
sudo apt-get dist-upgrade
sudo reboot

give your user password when requested, you don't see nothing when you type it, then press enter.

Thank you very very much for your kind suggestions. I tried your potential
solution and it did not work. Same msg appears:

"E: The value 'unstable' is invalid for APT::Default-Release as such a
release is not available in the sources
E: _cache->open() failed, please report."
Paradoxically both UpDateManager and Ubuntu Software Center work. The
problem is with Synaptic and somewhere in /etc/apt/ near as I can reason it
out.

What is the output of:

lsb_release -a; cat /etc/apt/sources.list

Thanks

It just returns the contents of the apt sources list with no indication or
pointers as to what might be the fault. Cleaned out all the PPA references
just in case there might be something there that caused it. The result was
still the same reference as before. Even went to another identical upgraded
drive that works and copied the files from /etc/apt thinking that would
solve the problem. Still got the same error msg. After two plus days of this
I am a bit tired so I figure there isn't much left to try. Waiting for a
friend to do a clean install and send me a copy of his /etc/apt so I can
compare.

Ok and the output of:

Thanks

Out put from cat /etc/apt/preferences below:

$ cat: /etc/apt/preferences: No such file or directory

I'm getting the exact same problem, except with the word "natty" flagged, rather than "unstable".

I've grepped all the files located within /etc/apt, but the only places i find "natty" are in lines flagged as comments.

I've cleaned out apt, deleted all the cruft from apt, and reinitiated the upgrade following the steps above.

The problem has not gone away.

The upgrade took place yesterday night.

My computer is a Compaq CQ40 laptop, AMD64 processor, 2 G of RAM; fwiw, i had some problems yesterday when i ran out of space on my /usr partition.

Looking forward to any help y'all can give, and if i find anything i'll pop back on and let y'all know.

Cheers --

Interesting. Don't have any help to offer at this point. Logic has failed so
I've started trying juju. Deleted Synaptic and reinstalled, cleaned the
cache, replaced /etc/apt folder with a clean install /etc/apt folder (if you
try beware of the gpg issues), looked at log files and in
/var/cache/apt/archives, and the error message keeps popping up. I've
haven't "pinned" any external repositories and have removed all PPA
references. At this point I am given to believe that it is a reference in
some obscure "apt" file that points to "unstable." I figure if I can find
that file and change unstable to stable that might solve the problem... just
got your latest message and found the unstable reference and changed it.
Problem solved. Thanks.

Tried the solution as found by Kyle Pearson and it resolved the problem for me. Thanks Kyle.

Kyle Pearson proposed the following answer:
The problem is in the /root/.synaptic/synaptic.conf

--
Found it on the last line before the closing "};" changed "unstable" to "stable."

Glad i could be of help.

Similar problem upgrade from xubuntu natty to oneiric. Synaptic throws error. I reported bug #880003.
Thanks to this thread I have fixed the problem.
/root/.synaptic/synaptic.conf had a value DefaultDistro "natty". I changed that to oneiric then attempted to load synaptic. Synaptic still threw an error but subtly different.
I reasoned there must be some other thing in the configuration so I did
sudo apt-get remove synaptic
sudo apt-get autoremove
sudo apt-get install synaptic.

Synaptic now launched correctly.
I will update my bug report.

I had the same problem with oneric to presise upgrade. I fixed it by changing in /root/.synaptic/synaptic.conf

DefaultDistro "oneric";

to

DefaultDistro "";

Then synaptic worked again. You can then go in and set your preferred distribution again, if you choose.
