Не конфигурируются несколько пакетов после перехода с 16.04 на 18.04

Собственно не ставятся printer-driver-pnm2ppa mariadb-server-10.1 ubuntu-desktop mariadb-server и ubuntu-gnome-desktop.

Зависает на этапе cp: overwrite '/usr/local/doc/vsh/initrd.img.old'?  Что это вообще такое? Разве оно не должно храниться в /boot/ каталоге?

Разобрался сам. Были запущены nginx, mysql, и php. Остановил и всё установилось как надо. Теперь хочу перейти на 20.04, но выдаёт ошибку E:The repository 'https://esm.ubuntu.com/infra/ubuntu focal-infra-updates Release' does not have a Release file

Дружище NyamPirozhok, а ты помнишь для чего и как подключал репозиторий  https://esm.ubuntu.com/infra/ubuntu ?
