NotImplementedError when adding or syncing

[Russ Brown]

I have been using the layman overlay fine for a while now, but this morning when attempting layman -S I got a traceback. So I removed the overlay and tried re-adding it again, and ended up with this:

# layman -a bazaar

* Failed to add overlay "bazaar".

[Mark Lee (malept)]

Strange...I can't duplicate this, although I'm using bzr1.6rc3.

$ /usr/bin/bzr get "http://bzr.malept.com/bazaar-overlay/"
Server does not understand Bazaar network protocol 3, reconnecting. (Upgrade the server to avoid this.)

You might want to try downloading the layman file and modifying it so the URL is http+nosmart instead of just http.

[Russ Brown (pickscrape)]

It appears to have been RC1. Thanks for the nosmart+http suggestion: with that I was able to get the overlay updated so I could upgrade to RC3. With that in place I was able to delete the overlay and use it properly again via the usual method.

Marking this as Invalid since there was no fix to commit or release. :)

Thanks!
