I’m using Ubuntu 22.04 LTS and don’t have this problem, and Linux Mint 21 should be very similar as it is based on it. However if you google “No usable version of libssl was found” you’ll find references to some Ubuntu 22.04 compatibility issue with the openssl library, and some fixes are suggested. I would try monkey with that, and if you can’t fix it then try reinstalling operating system to Ubuntu 22.04 LTS (not Mint) and try again.

Я не собираюсь устанавливать Ubuntu, так как оно не является целевой ОС.

Что ж, тогда погуглите сообщение об ошибке openssl и попробуйте некоторые из предложенных исправлений.

Я не пишу на форумах, если решение есть в поиске.

К сожалению. часто бывает так, что на мои вопросы нет ответов в сети…

З.Ы.: Задолбался переводить на английский.
