Every time I do anything I do anything related to sudo (mostly installing repositories), it says command not found.

I type:

sudo add apt-repository ppa:ppsspp/stable

It then says

sudo:add-apt: command not found

Sometimes it tells me to manually run configure --a, which I do, and it still doesn't work. Anyone know how to fix???

I'm on Ubuntu 18.04 LTS

    Please don't post screenshots of text. Instead edit your question to paste the text from your terminal. – guntbert Jul 19 '19 at 21:33

    Your question seems to have several typos, and your output looks like classic typo confusion. Your Ubuntu system is NOT forgiving of typographical errors. Double-check your typing before hitting <enter>. Pay close attention to mixing up spaces, dots, dashes, and underscores. That's common for new folks. – user535733 Jul 19 '19 at 21:48

    ...and when you include text from the terminal, copy and paste it instead of typing. Right now, the command in the question doesn't match the error message, which is a clear giveaway that the question doesn't contain accurate information for anyone trying to answer it. – ilkkachu Jul 20 '19 at 8:28

The command is add-apt-repository, you're missing the second hyphen.
