While updating packages information all added repositories seem to be active but much of it fail to download.
So I'm trying to manage repositories but for some reason I fail to get to the list of them both through synaptic and Terminal. Synaptic seems to try but doesn't open the box after a while, and the last one returns "bash: /etc/apt/sources.list: Permission denied" to "/etc/apt/sources.list" (as root, of course).
So I went to the folder, but there's almost nothing there. Just a .txt that goes:
### THIS FILE IS AUTOMATICALLY CONFIGURED ###
# You may comment out this entry, but any other modifications may be lost.
# deb http://dl.google.com/linux/chrome/deb/
Do you think having added wheezy repositories to squeezy could be a cause? I got GIMP and Inkscape new versions from them, but I didn't install anything else.
I appreciate any help.
(very newbie, BTW)
