Hi, probably you have solved this error already, but for everyone else encountering this problem, you can try this:
Open terminal:
sudo chown -R tianyanggao:staff ~/.config
sudo chmod -R u+rw ~/.config
You’ll be asked for your user password when you enter this command.
After this - at least in my case - the installation ran without issues (in my case installing Conda via Pinokio)
Best regards
Christian
