I look This post

The "sudo add-apt-repository --remove ppa:" command didn't work for me.

Tried manually remove from /etc/apt/sources.list but access is denied

Is there other way to remove the broken repository

  • Can't you uncheck it from the Software & Updates in the Other Software tab?

  • when you tried to manually remove it from the sources.list file did you use sudo (to raise your privileges/permissions) ?

  • Does this answer your question? How can PPAs be removed? and How to remove a repository?

The wget command does not add a ppa in the first place, it simply downloads files over http. The command you posted simply downloads Wine from the internet.

However, if you find you would like to remove a source manually, you can do so by opening /etc/apt/sources.list and removing the line that contains the source.

You can do this using the command sudo nano /etc/apt/sources.list. Sudo is used as you require root privileges to edit the file.


The command to download mono is:

wget https://dl.winehq.org/wine/wine-mono/4.7.1/wine-mono-4.7.1.msi

then you have to run it in the WINE prefix that you want to install mono in.

To correct the sources list, you need root privileges:

sudo nano /etc/apt/sources.list
