Hellu,
I tried to add ppa but fallback to this error.
how could i fix it?
Thanks
Hello,
PPA repositories are made for Ubuntu and distributions based on it, hence this error.
The easiest solution would be to modify the /etc/os-release file.
Also try to install software-properties-common with APT.
However, I advise you to find an alternative way to install your software without using a PPA repository.
