I think I might be a bit dense, as this cropped up in the other thread as well yet I again forgot to account for it. See <https://lists.gnupg.org/pipermail/gnupg-users/2018-February/059981.html> Other programs on your system might pick up your /usr/local/bin/gpg and start using it as if it were /usr/bin/gpg at version 1.4. This will expose wrong assumptions in those programs, causing them to malfunction. The thing about the partially statically linked version mentioned in > <https://lists.gnupg.org/pipermail/gnupg-users/2018-February/059969.html> is that it is in /opt, where your system will not use it unless very explicitly configured to do so. In fact, I wouldn't even add it to your own $PATH, because some other program you invoke might use it as well. I notice that often when someone asks "I do this and it goes wrong, what am I doing wrong", I will think "oh, this and that is what is going wrong, do it like this" instead of "Wait, should you even be doing that?" :-). I don't think there is a fool-proof way to install GnuPG 2.1+ on a Linux distribution that ships 1.4 and/or 2.0. It will always require being cautious and knowing exactly what is using what. Luckily, if we as end-users have a bit more patience, I think in the end all our distributions will have done the hard work of fixing all of this for you. I count myself lucky to be running Debian stable. For once, that means I'm running a newer version than others! :-D Peter. -- I use the GNU Privacy Guard (GnuPG) in combination with Enigmail.
