Не могу установить mailutils Ubuntu 18.04

Кажется, я не могу установить mailutilsв убунту 18.04. Это ошибка зависимости, и я не могу найти информацию об этой проблеме где-то еще.

Команда: sudo apt install mailutils

Выход:

      The following packages have unmet dependencies:
 mailutils : Depends: guile-2.0-libs but it is not going to be installed
             Depends: libmailutils5 but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Затем я запустил это: sudo apt install guile-2.0-libs

Выход:

      The following packages have unmet dependencies:
 guile-2.0-libs : Depends: libgc1c2 (>= 1:7.2d) but it is not installable
                  Depends: libltdl7 (>= 2.4.6) but it is not installable
E: Unable to correct problems, you have held broken packages.

я пытался установить libgc1c2вручную: sudo apt install libgc1c2

Выход:

      Reading state information... Done
Package libgc1c2 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
