I have my secret key on two machines. On one of them, I added a new uid and
uploaded to a keyserver. On the other, I refreshed, and received the uid. When
I use
gpg --clearsign --local-user "Bas Wijnen <wijnen@debian.org>" on the first
machine, everything works fine. However, on the other machine, it says "gpg:
error reading key: secret key not available". When using a different uid from
the same key (shevek@fmf.nl), everything works fine. gpg --list-keys wijnen
shows no other keys than that one.
