How do i delete apps!?

@anonnetuser, you mentioned kde on fedora isnt that stable in a different topic:

should i use some other distro instead? since i am also having problems on fedora (i had to reinstall it due to it) i still have time i just got it like yesterday so i wont lose that much work if i switch now. i keep hearing kubuntu is very stable but i js dont like the name tbh
