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.

    Why do you want to remove it? Does keeping it installed force Enigmail to use it?

You neither must remove GnuPG (1) installed as gpg, nor can safely. It can safely coexist with GnuPG 2 installed as gpg2, 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.

  • It would be helpful to have the possibility to update this information from official sources at any time. Is there a website or similar where this can be tracked?

  • This Q&A is form 2015 -- in the last two years, a reasonable number of packages has been migrated from using GnuPG 1.4 to GnuPG 2.0/2.1. In fact, more and more distributions ship GnuPG 2.1 as gpg, while GnuPG 1.4 is installed as gpg1. As far as I know (but I haven't checked recently), Ubuntu (and Debian) is using GnuPG 2.0/2.1 in the package manager for day-to-day usage, but some development tools still rely on the old version.

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.
