I access internet from the college proxy server. So, when I add an apt-repository as sudo add-apt-repository ppa:nilarimogard/webupd8
, I get an error saying
Cannot add PPA: 'ppa:~nilarimogard/ubuntu/webupd8'.
ERROR: '~nilarimogard' user or team does not exist.
When I was on Ubuntu 16.04, I used to disable proxy settings and connect to mobile network and then add the repository.
When I do the same on Ubuntu 18.04, It shows 0% [Connecting to 172.16.2.30 (172.16.2.30)] [Connecting to 172.16.2.30 (172.16.2.30)] [Connecting to 172.16.2.30 (172.16.2.30)]
, where 172.16.2.30
is the proxy address. It is showing the above line even after disabling the proxy settings. How can I add the apt repository?
