I think this is a display problem. I bet that bzr-rebase is in a Format3
repository - with rich roots.

Is this still valid ?

[John A Meinel (jameinel)]

Well, you still can't fetch from a RichRoot into a non-rich root. But that is by design (Won't Fix).

At present the result is:

$ bzr init --rich-root source
$ bzr init --pack-0.92 target
$ bzr commit -m "unchanged" --unchanged source
$ cd target
$ bzr pull ../source
Format <RepositoryFormatKnit4> for file:///.../source/.bzr/ is deprecated - please use 'bzr upgrade' to get better performance
bzr: ERROR: KnitPackRepository('file:///.../target/.bzr/repository/')
is not compatible with
KnitRepository('file:///.../source/.bzr/repository/')
different rich-root support

So we don't actually give the fact that the source has rich roots and the target does not, but we *do* tell the user that there is a rich-root incompatibility. Is that sufficient?

[Robert Collins (lifeless)]

Jelmer, this should be 'wont fix' according to the history - if marking something contrary to its log or that is otherwise ambiguous please include some rationale :)

[Robert Collins (lifeless)]

Oh also, the 'bzr' project does not use 'Triaged' as per our HACKING guidelines.

[Jelmer Vernooij (jelmer)]

Ok, fair enough.

The error message is still confusing for people who are not familiar with rich roots, it should probably refer to whatever docs there are about rich roots and perhaps mention "bzr upgrade".

This error happened to me when I was trying to use, in Jaunty, a branch that I modified while using Intrepid. The version of bzr was 1.6. To solve it, I had to use the bzr PPA (https://edge.launchpad.net/~bzr/+archive/ppa) in order to get the 2.2.2 version.
