2. Remove your `NMBGIT` repository (e.g. `mv .nmbug .nmbug.bak`).
3. Use the new `clone` command to create a fresh clone:
- nmbug clone http://nmbug.tethera.net/git/nmbug-tags.git
+ nmbug clone https://nmbug.notmuchmail.org/git/nmbug-tags.git
4. If you had local commits in step 1, add a remote for that
repository and fetch them into the new repository.
