Cannot add PPA - "user or team does not exist"

When I run this command:

sudo add-apt-repository ppa:webupd8team/sublime-text-3

I get the following error:

Cannot add PPA: 'ppa:~webupd8team/ubuntu/sublime-text-3'.
ERROR: '~webupd8team' user or team does not exist

My proxy settings are working properly

what's the solution?

Solution 1:

I found a working solution at add-apt-repository derrière un proxy d'entreprise (in French).

To summarize it, you have to export the env variables HTTP(S)_PROXY, lowercase and uppercase in your term.

Then execute:

sudo -E add-apt-repository ppa:...

The -E option will preserve the env vars defined above, and will enable the proxy use.

Solution 2:

Running add-apt-repository without internet connection really does produce the same error message as in the question. One might consider the error message being incorrect or confusing like this as a bug though.

Adding the corresponding repositories is not enough unless you have an internet connection.

I fixed this by making an internet connection because the repositories had already been added.

Check this with: $ ping www.google.com

Solution 3:

In my case it was my company's man-in-the-middle fake SSL certificate that caused this misleading error. If you are on corporate internet, you may need to install your company's SSL cert at /usr/local/share/ca-certificates/yourcompany.crt and run sudo apt-get update && sudo apt-get install ca-certificates -y && update-ca-certificates

Solution 4:

Also, consider your VPN activity when using WSL as in general VPN's and WSL (Ubuntu) don't mix well. So if you are receiving these errors with a VPN connected, try disabling your VPN and running the command again. This is an odd fix that should be attempted if the above mentioned solutions aren't working for you.
