Пакеты установки со 'способностью'

Я пытаюсь установить некоторые пакеты с помощью "способности" (человечность 16.04), но я не знаю, как завершить установку, когда я достигаю этой точки:

sudo aptitude install -f mariadb-galera-server

Keep the following packages at their current version:

1) mariadb-client-5.S [Not Installed)
2) mariadb-client-core-5.5 [Not Installed)
3) mariadb-galera-server [Not Installed]
4) mariadb-galera-server-S.5 [Not Installed]


Accept this solution? [Y/n/q/?] 

также это дает эти опции, но они не работают, или я не знаю, как использовать их:

<ACTION> pkg... : adjust the state of the listed packages, where ACTION is one of:

'+' to install, packages
'+M'to install packages and immediately flag them as automatically installed
‘-‘ to remove packages to purge packages
‘=‘ to place packages on hold
‘:‘ to keep packages in their current state without placing them on hold
‘&M’ to mark packages as automatically installed
‘&m’ to mark packages as manually installed

и эти r целые данные решения:
