Hi Csepp thanks for your answer > I'd leave 3.6.2 in my default profile. Does this mean, every time I am doing a guix pull and guix package --upgrade I have to add: --do-not-upgrade musescore so that musescore stays at the version 3.6.2 ? (If I forget to add this, than it will upgrade to version 3.4 and I can than only switch back one generation and do the guix package --upgrade --do-not-upgrade musescore again) Is it like this?
