How to solve these Problems?

Answer 1

The issue was resolved by removing -O- from the wget instruction http://repo.ajenti.org/debian/key -O- | sudo apt-key add -
What was he responsible for and how did it affect the package itself?

Answer 2

Try wget http://repo.ajenti.org/debian/key -O- | sudo apt key add-

Answer 3

Had the same problem.
The solution was found on the site https://infoit.com.ua/linux/kak-ustanovit-ajenti-c...
I have nothing to do with this site. Just found a working manual.
It would be great if this instruction migrated to the official page https://support.ajenti.org/ru/knowledge-bases/5/ar...
