Ubuntu 21.10 Как установить imagemagick и webp

Я попытался установить imagemagick и webp, но получаю сообщение об ошибке:

      $ sudo apt install imagemagick
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Package imagemagick is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'imagemagick' has no installation candidate

$ sudo apt install webp
Reading package lists... Done

Reading state information... Done
E: Unable to locate package webp

Могу ли я установить их с помощью apt?
