How do I revert my source.list from the source.list.backup?
Solution 1
With four commands:
sudo apt-add-repository main
sudo apt-add-repository universe
sudo apt-add-repository multiverse
sudo apt-add-repository restricted
Or move or copy your backup
sudo cp /etc/apt/source.list.backup /etc/apt/source.list
The folder /etc/apt/source.list.d
has always been a folder, a sub-folder of /etc/apt
. After the removal of /etc/apt/source.list
, the folder /etc/apt
usually contains only this folder.
Solution 2
The sources.list
can be generated in multiple ways. The GUI provided in ubuntu basically generates that file (it is in Settings -> Software). There is /usr/share/doc/apt/examples/sources.list
which is in all the proper format. You can copy the example file to original file, cp /usr/share/doc/apt/examples/sources.list /etc/apt/sources.list
And there is also online generator https://repogen.simplylinux.ch/
But your file should remain in /etc/apt
directory. You can revert changes with sudo mv /etc/apt/sources.list.backup /etc/apt/sources.list
