Hi,

Can you please install this package and try again:

sudo apt update
sudo apt install gnupg

Let me know how it ends.

Regards,

Sharif

Hi,

Your outputs are normal.

This is what I get when I execute the script:

root@Sharif-PC:~# bash inst_repo_ubuntu.sh
/etc/apt/sources.list.d/zextras.list does not exist, it will be added to the list of repositories.

Hi,

It looks right.

Could you please remove the zextras.list file and again run the script the add it. Please dump the output.

Sorry for all the troubles you have to go through.

Sharif
