Cannot add PPA on Ubuntu 17.10

Question

Whenever I try to add PPA, I am getting and error. Below is one such case.

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

I am using an institution HTTP proxy. I have tried setting HTTP_PROXY and ALL_PROXY in the environment without any success. Also, I have tried out the other solutions in other questions with the same result.

Try to add this PPA manually with

cat <<EOF | sudo tee /etc/apt/sources.list.d/sublime.list
deb http://ppa.launchpad.net/webupd8team/sublime-text-3/ubuntu artful main 
deb-src http://ppa.launchpad.net/webupd8team/sublime-text-3/ubuntu artful main 

EOF

and add its GPG key with

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys EEA14886

or

sudo gpg --keyserver pgpkeys.mit.edu --recv-key  EEA14886
sudo gpg -a --export EEA14886 | sudo apt-key add -
sudo apt-get update

or (with your proxy address and its port in the command)

sudo apt-key adv --keyserver keyserver.ubuntu.com \
     --keyserver-options http-proxy=http://proxy_address:proxy_port \
     --recv-keys EEA14886

then

sudo apt-get update

and so on.

Note: this answer is based on these : first, second and third.

Update: try to get and install the package manually

cd /tmp
wget http://ppa.launchpad.net/webupd8team/sublime-text-3/ubuntu/pool/main/s/sublime-text-installer/sublime-text-installer_3126-2~webupd8~1_all.deb
sudo apt-get install ./sublime-text-installer_3126-2~webupd8~1_all.deb

The first command ran pretty well. But then, this is what I got. https://imgur.com/a/O2th8 – Somnath Rakshit Nov 27 '17 at 17:33
I updated my answer, you can try pgpkeys.mit.edu method above. – N0rbert Nov 27 '17 at 17:46
gpg: WARNING: unsafe ownership on homedir '/home/somnath/.gnupg' and gpg: keyserver receive failed: No keyserver available is what I get – Somnath Rakshit Nov 27 '17 at 17:50
Try last one with proxy settings in the command line. Replace proxy_address:proxy_port with your values and try. – N0rbert Nov 27 '17 at 18:06
Still, getting the same result. https://imgur.com/a/LXYqD – Somnath Rakshit Nov 28 '17 at 03:29
Hi @N0rbert, can you please help me? – Somnath Rakshit Nov 28 '17 at 15:20
I have three new ideas: download GPG key while connected to the 3G/4G mobile internet (Wi-Fi hotspot on phone should be enabled), VPN, or try to setup local tor proxy. – N0rbert Nov 28 '17 at 15:51
Same result coming for all 3. :( – Somnath Rakshit Nov 28 '17 at 18:42
@SomnathRakshit please read my update above. – N0rbert Dec 03 '17 at 17:56
