E:Index file type '.0-3' is not supported

[Diaa Sami]

After updating some packages I got
E:Index file type '.0-3' is not supported

Thanks for your bugreport.

Could you please open a terminal window (e.g. gnome-terminal) and run:
$ sudo apt-get install -f
and tell me what the output of that is?

I want to add that everything worked normally after I got this error.
As for the output of
$ sudo apt-get install -f
it's

Which is normal I think.

Another thing to mention is that I get an error message frequently after using synaptic, it says
E: The package cache file is corrupted
and then synaptic exits immediately, but after that everything works fine.

[Diaa Sami (diaa.sami)]

Here is the complete error message:
E: The package cache file is corrupted
E: _cache->open() failed, please report.

So you get the error in synaptic and/or update-manager when you start them ? And then the app starts up normally?

[Diaa Sami (diaa.sami)]

yes but usually it happens in Synaptic or Update Manager *after* an update or an upgrade and then the application closes, next time the app starts normally.

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue for you? Thanks in advance.

[Diaa Sami (diaa.sami)]

I didn't get it in a while, I think this bug can be closed.

[Jean-Baptiste Lallement (jibel)]

Thanks for following up. I'm closing this report due to your last comment.
Don't hesitate to submit any new bug.
