I don't know what happened, but one day my computer had some sort of a system error and could no longer update itself.
The software center will not open, it will begin to initialize and then a message pops up saying theres a system error and needs to shut down the software center. Then another box pops up after I go to report it saying it was unable to identify source or package name.
I also can't extract a zipped folder to anything, or reinstall Ubuntu from a USB boot drive anymore, it keeps telling me my my computer isn't compatible when I know for a fact it is, because thats how I got Ubuntu on here in the first place.
The only thing I know about this error is that a message popped up after I went to check for updates saying to report the problem and include this message in the report:
E:malformed line 56 in source list /etc/apt/sources.list (dist parse)
bash: /etc/apt/sources.list: Permission denied <--this is the message that pops up when i attempt to access this line. . .
It also called it a bug. I just want to know how to either get rid of the bug completely or find some way to be able to reinstall Ubuntu again. I know it's not a lot of information, but It's all I can give. Sorry.
