I am trying to install dupeguru on Zorin 16.
I can not install it via PPA:
% sudo add-apt-repository ppa:dupeguru/ppa
LSB codename: 'focal'.
Version of base-files: '11ubuntu5.6+zorin1'.
Your LSB codename isn't a valid Linux Mint codename.
Please check your LSB information with "lsb_release -a".
I also can not install it via pip.
% pip3 install dupeguru
ERROR: Could not find a version that satisfies the requirement dupeguru (from versions: none)
ERROR: No matching distribution found for dupeguru
What can I do?
