"Failed to check for installed and available applications"

[louisp]

Just got this in add/remove applications and I have no idea why.

typed
gksudo gedit /etc/apt/sources.list in terminal and here are my results.

thanks for any help.

And after opening Synaptic I get this error:

E: Type ‘“deb’ is not known on line 57 in source list /etc/apt/sources.list
E: The list of sources could not be read.
Go to the repository dialogue to correct the problem.
E: _cache->open() failed, please report.

It may be worth removing the quote marks in the last line of your sources.list.

Thanks, works now.

Also, is it a really good idea to have feisty repos in intrepid release?
