Please help. I've been trying to install skype for a very long time and I've tried countless fixes.

UPDATE: I can't install steam because of this either.

If you show us your /etc/apt/sources.list file, someone may be able to explain how those lines are problematic. — Gunnar Hjalmarsson, Jul 10 '15 at 07:50
Right sorry. Edited. And thank you but after I had breakfast this morning I did a fresh install and everything is working fine now. — Nathan, Jul 10 '15 at 19:02

I had sometimes the same issue. I guess you can not install anything right? I fixed it with 2 solutions.

First try better mirror for updates.

Finding fastest mirror from the graphical mode is very easy. All you to do is open Synaptic package Manager, go to Settings -> Repositories. From the Ubuntu Software section, Select “Other” in the “Download From” drop-down box, and click on Select Best Mirror.

And second remove any ppa that is not working.

Remove a PPA using a GUI: A PPA can also be removed by opening Software Sources (Ubuntu Software Center > Edit > Software Sources), then going to the "Other Software" tab, selecting the PPA you want to remove and then clicking the "Remove" button.

Each PPA should have two lines here, one for the compiled packages and one for the source, so remove both lines.

Source

One of these may help you.

Although your post may answer your question it is suggested to put the essential information from the links in your post rather than just the links. – Ron Jul 10 '15 at 06:49
I couldn't install Synaptic package manager because of the pre-existing problem and after removing all ppa it still gives me the same errors. – Nathan Jul 10 '15 at 06:49
You have a malformed line in your sources file. See http://askubuntu.com/questions/78951/how-do-i-remove-a-malformed-line-from-my-sources-list – Ron Jul 10 '15 at 06:50
My fault, sorry! Edited – trelozakinthinos Jul 10 '15 at 08:48
I didn't see this solution in time but when I woke up I tried a fresh install and it seems to be working fine now. Thanks for all your help! – Nathan Jul 10 '15 at 19:00
