Recently I had to revoke one of my UIDs and add a new one in my main GPG Key. As I expected the new UID became primary and I tried to change it back to the original one (it's not the revoked one). Strangely I cannot get the primary uid to change. I tried it with
--edit-key but there is no different output.
uid 2 and then type
primary. After it I
save it but there is no change. If I try to redo the steps it tells me after
save there has been no change.
Additionally I noticed that my new UID has correct prefferences while all the others are set to minimum. (3DS, SHA1, etc.) When I try to update them with
setpref I sometimes get a warning that none of the uids is marked as primary.
Is there something I missed or can do to get a new result?
