I don’t know what is wrong or what happened, but I can’t make gpg cli work with any encrypted server. Regardless of which version I install.
I tried all versions from 2.34 down to 2.3.34.
None work with an encrypted keyserver. They all work with non-encrypted keyservers.
2.3.4 work great with encrypted keyservers in Ubuntu.
All I know is that hkps://keyserver.ubuntu.com used to work great, before I installed 4.0.0.
