Repository KnitPackRepository('…') is not compatible with repository RemoteRepository('…')

[Ben Finney]

Howdy all,

I have not upgraded Bazaar for some time (and am not in a good
position to do so), but today I'm getting failures on trying to work
with a checkout of a remote repository.

=====
$ bzr version
Bazaar (bzr) 1.5
  Python interpreter: /usr/bin/python 2.5.4
  Python standard library: /usr/lib/python2.5
  bzrlib: /usr/lib/python2.5/site-packages/bzrlib
  Bazaar configuration: /home/bignose/.bazaar
  Bazaar log file: /home/bignose/.bzr.log
[…]

$ bzr checkout bzr+ssh://delrosa.madmonks.org//srv/bzr/whitetree/public/bignose/roaming-profile/ spam/
bzr: ERROR: Repository KnitPackRepository('file:///home/bignose/spam/.bzr/repository/') is not compatible with repository RemoteRepository(bzr+ssh://delrosa.madmonks.org//srv/bzr/whitetree/public/.bzr/)
=====

An existing checkout, which has been working fine for many months,
gives the same error now:

=====
$ cd .roam/
$ bzr info
Checkout (format: pack-0.92)
Location:
       checkout root: .
  checkout of branch: bzr+ssh://delrosa.madmonks.org//srv/bzr/whitetree/public/bignose/roaming-profile/

Related branches:
    push branch: bzr+ssh://delrosa.madmonks.org//srv/bzr/whitetree/public/bignose/roaming-profile/
  parent branch: /media/sdb1/bazaar/roaming-profile
  submit branch: bzr+ssh://delrosa.madmonks.org//srv/bzr/whitetree/public/bignose/roaming-profile/

$ bzr update
bzr: ERROR: Repository KnitPackRepository('file:///home/bignose/.roam/.bzr/repository/') is not compatible with repository RemoteRepository(bzr+ssh://delrosa.madmonks.org//srv/bzr/whitetree/public/.bzr/)
=====

The remote machine, ‘delrosa.madmonks.org’, is running the same version of Bazaar:

=====
$ $ bzr --version
Bazaar (bzr) 1.5
  Python interpreter: /usr/bin/python 2.5.2
  Python standard library: /usr/lib/python2.5
  bzrlib: /usr/lib/python2.5/site-packages/bzrlib
  Bazaar configuration: /home/bignose/.bazaar
  Bazaar log file: /home/bignose/.bzr.log
[…]

The log shows a traceback:
