bzrlib.errors.KnitCorrupt: Knit inventory corrupt

[Ben Finney]

Howdy all,

I'm trying to upgrade a repository to 'rich-root-pack' format, in
order to continue using it as a mirror for some branches.

=====
$ bzr upgrade --rich-root-pack .
starting upgrade of file:///srv/bzr/whitetree.dirstate/public/
making backup of tree history
file:///srv/bzr/whitetree.dirstate/public/.bzr has been backed up to file:///srv/bzr/whitetree.dirstate/public/backup.bzr
if conversion fails, you can move this directory back to .bzr
if it succeeds, you can remove this directory if you wish
starting repository conversion
