Warned by Enigmail they soon won't support gnupg and switch to gnupg2 I installed the later.
Now trying to remove gnupg, I see a bunch of software will be removed as a consequence:
apt apturl enigmail (!) nautilus-share python-software-properties seahorse software-center (=:q) software-properties-common+-gtk ubuntu-desktop+-extra-keyring+-minimal and unattended-upgrades.
A big bit frightening isn't it? So the title question.
You neither must remove GnuPG (1) installed as
gpg
, nor can safely. It can safely coexist with GnuPG 2 installed asgpg2
, which is supported by Enigmail.The "old" GnuPG version 1
gpg
is still used intensively by Ubuntu's (and Debian's) package management system and is not ready to be replaced by GnuPG 2 yet, at least doing so is not officially supported and might break your system.GnuPG is an important part of the system and used for example by the package manager. You can't remove it without breaking the system.
