Synaptic Manager Error [duplicate]

Question

I recently downloaded Skype Beta which works fine but I have been getting an error while updating packages from Synaptic Manager:

W: Target Packages (main/binary-amd64/Packages) is configured multiple times in /etc/apt/sources.list.d/skype-stable.list:1 and /etc/apt/sources.list.d/skypeforlinux.list:1
W: Target Packages (main/binary-all/Packages) is configured multiple times in /etc/apt/sources.list.d/skype-stable.list:1 and /etc/apt/sources.list.d/skypeforlinux.list:1
W: Target Translations (main/i18n/Translation-en_US) is configured multiple times in /etc/apt/sources.list.d/skype-stable.list:1 and /etc/apt/sources.list.d/skypeforlinux.list:1
W: Target Translations (main/i18n/Translation-en) is configured multiple times in /etc/apt/sources.list.d/skype-stable.list:1 and /etc/apt/sources.list.d/skypeforlinux.list:1
W: Target DEP-11 (main/dep11/Components-amd64.yml) is configured multiple times in /etc/apt/sources.list.d/skype-stable.list:1 and /etc/apt/sources.list.d/skypeforlinux.list:1

NOTE: It hasn't been long since I switched to Linux so if someone can explain the error and provide some help, I'll appreciate it.

Answer 1

The Skype repository is defined twice. Once in /etc/apt/sources.list.d/skype-stable.list and again in /etc/apt/sources.list.d/skypeforlinux.list. You should remove one of them... but which one? Do this...

In terminal...

cat /etc/apt/sources.list.d/skype-stable.list
cat /etc/apt/sources.list.d/skypeforlinux.list

the output of the cat commands may be different. The first one will probably be for the Skype stable version, and the second one will be for the beta version of Skype. Review them carefully.

You'll want to either...

- delete the skype-stable.list file
- delete the skypeforlinux.list file

To do one of the above... do either...

sudo rm -i /etc/apt/sources.list.d/skype-stable.list
sudo rm -i /etc/apt/sources.list.d/skypeforlinux.list

Update

It looks like Microsoft used two different repo .list names depending on when you installed Skype. The latest installer, skypeforlinux-64.deb actually lays down a /etc/apt/sources.list.d/skype-stable.list file.

The /etc/apt/sources.list.d/skypeforlinux.list file came from a previous Skype install... so that's where you end up with two .list files, and causes all of the problems.
