unmet dependencies, how do I get the dependencies if I cannot update the release 12.10; Error in Package Manager; error opening the cache (E:Malformed line 58 in source list/etc/apt/sources.list (dist parse), E:The list of sources could not be read., E:the package lists or status file could not be parsed or opened,). Can I repair the system online, or repair without reinstalling; can another form of update repair and install the dependencies?

I read the Q&A's, problem did not resolve; I am familiar with the dependencies under Python 2.7 requirements, but not 3.0 looking at the text under etc/apt/source.list it only has 29 lines, not 58 with code, the rest is # non-code explanations. But I do not see how the last 4 lines are malformed.

this can be solved by typing the following command in the terminal

sudo rm /var/lib/apt/lists/* -vf

then update your system by entering the following command in the terminal

sudo apt-get update && sudo apt-get upgrade

after this there should be no errors and everything should work fine
