it sounds like you might have created the systemd unit files yourself.
If you're running GnuPG from a distribution-supported package, that
package should have shipped them for you already (see for example the
packaging in debian).
even if you're building it yourself, or if your distro doesn't ship
them, i recommend starting from the example unit files in
doc/examples/systemd-user/ in the source tree. can you compare those
unit files with your own unit files?

I'm assuming that sysu is some sort of local alias for "systemctl
--user" please let the list know if that's not the case.

these are not the standard socket locations, which is probably why gpg
isn't finding them for you.

try using the shipped user service units instead :) If that doesn't work
for you, or if you have any suggestions for improvements, i'm happy to
help review and debug.
