@af0815,
I cannot agree, because I have used that installation, from the Linux Mint repository, for more than an year! I used to be able to install components and rebuild the IDE without any hassles. My current problems appeared when I attempted to install the lazdbexport component package which is shipped with Lazarus.
I have never heard of 'fpcupdeluxe' and do not want to install anything from git which will require compilation from scratch (which, in my personal experience in accordance with Murphy's Law, will only create more poblems!)
Regards,
