Hello dear @vasilis!
Recently I’ve got a strange problem (after last flair upgrade). For some reason, I don’t have permission to open flair (see screenshot). It says:
bash: /usr/local/bin/flair: Отказано в доступе
“Отказано в доступе” means access is denied. I found that I don’t have permission to open flair folder and after I changed the rights (it was only accesible from root) everything was ok. Also, I found that icons for .flair and .inp files disappeared, very similar to the Missing flair mime icons topic. Installation is from Ubuntu 20.04 repo.
Thank you in advance!
