Ubuntu 14.04 is not longer supported by most PPA because its reached its end of life.

Use a newer ubuntu version, like 20.04 LTS. Also php7.1 has already reached end of life too. We already reached php8 now.

I recommend that you learn docker and refactor your code / install your app for php7.4 or php8 (whichever works with php imap) and ubuntu 20.04. I know, its a lot of work but its either this or get left in the dust:/
