Upgrade v55 gpg error


I try to upgrade vom v53 to v55 but there is a gpg error:

FAILED: add-apt-repository -y ppa:duplicity-team/duplicity-release-git
Error: retrieving gpg key timed out.

Do I have to change something in my Ubuntu installation?


As you can see from the error message, the remote server timed out while you were retrieving the gpg key.

99% of the time, trying again a short time later is the solution. @celk
