Hi @Kanon,

I didn’t quite understand what is the error.

If you type in:

sudo add-apt-repository ‘deb focal-cran40/’

You receive :

sudo add-apt-repository 'deb focal-cran40/’

Is that correct? Can you please give a little bit more information on the case?

Additionally, can you please try and do an update and upgrade prior to adding the repository to see if that would help out?
