Ok, this could probably be of less pain if I haven’t decided to manually delete old version folders that the apt couldn’t remove due to those folders not being empty. That pop up window you said it should pop up, it did but the 1st option that was to use the default global library was greyed out. heheh. Anyway I think I don’t need to open these old projects because I already have them on PCBs, so it’s probably ok.
I’ll be trying to figure out now the new version and try to find the SMA connector schematic symbols and later the footprints.
