Running V5 on Linux Mint 19 via PPA.
When I open a .sch I get a pop up message that I need to create a global symbol library. The explanation says if you are not sure (and I am not) then select the default. The option marked as recommended is greyed out, so cannot be selected. I cannot even exit from this. The only option to get out is to create an empty file and select that.
What should I do? Do I need a global symbol library and if so where do I find one?
Having created a blank file and used that I get another pop up saying The following libraries were not found and it lists about 30 libraries. What do I need to do about that?
