I got big problems with Skype application on ubuntu 22.04. There was a lot of bugs and I finally decided to remove this app and switch to web version. I uninstalled this but skype still hold to something in my system.

When I am trying to execute: sudo apt update I get this:

$ sudo apt update

I dont't want to see this warning anymore. I just want to get rid off this and also know how to deal with this kind of problem in the future.

I was trying to do this (Removed skype still have apt get update errors about skype):

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

but:

$ sudo rm /etc/apt/sources.list.d/skype-stable.list
rm: cannot remove '/etc/apt/sources.list.d/skype-stable.list': Operation not permitted

Can anyone help me with this? So annoying...

Updates:

$ ls /etc/apt/sources.list.d
deadsnakes-ubuntu-ppa-jammy.list  skype-stable.list
docker.list                       skype-stable.list.save
docker.list.save                  vscode.list
google-chrome.list                vscode.list.save
google-chrome.list.save

  • Look under all of the .list files under /etc/apt especially /etc/apt/sources.list and remove the sources for Skype. – Nmath Oct 08 '22 at 17:26
  • @Nmath Under /etc/apt/sources.list.d – Pilot6 Oct 08 '22 at 17:27
  • Please add output of ls /etc/apt/sources.list.d to your question. – Pilot6 Oct 08 '22 at 17:28

    @Pilot What is the confusion? /etc/apt/sources.list.d is under /etc/apt OP needs to remove offending entries from any source list in this directory or any subdirectories. – Nmath Oct 08 '22 at 17:29
  • Did you edit the /etc/apt/sources.list.d and remove any entries for skype. It is a file that controls what PPA s will be used on update. Your command does not edit the file it tries to remove some file that is most likely not there. – David Oct 08 '22 at 17:29
  • I edited my post @Pilot6 – BiggestUbuntuNoobie Oct 08 '22 at 17:31
  • @David yes I was doing something following instructions from other posts but that I don't remember what I did exactly :/ – BiggestUbuntuNoobie Oct 08 '22 at 17:33
  • Whatever problems you had with Skype was likely due to NOT updating it because the repo needed coorection. Actually the repo wasn't needed at all, it must have come from old outdated instructions. Skype is now available as a SNAP, updated and working fine. That's all. – ChanganAuto Oct 08 '22 at 21:16

Okay my fix was answer from that post: Permission denied: '/etc/apt/sources.list.d/google-earth.list'

The file was immutable I have no idea why.

I executed this command to find out this file was immutable:

$ lsattr /etc/apt/sources.list.d/skype-stable.list
----i--------e-- /etc/apt/sources.list.d/skype-stable.list

after that I removed file immutability:

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

and finally deleted it:

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