Error upgrading to KnitPack1 from Knit3 using 'bzr upgrade'

Asked by Max Bossino

Hi,

Every time I issue a bzr command within the mira branch (obtained from this repository: https://code.launchpad.net/~mira-core-development-team/mira/trunk), bzr issues a warning to upgrade the repository from RepositoryFormatKnit3 to RepositoryFormatKnitPack1 using the 'bzr upgrade' command.

Both a fellow developer and I have tried to upgrade the repository using this command to no avail. The error that is produced when 'bzr upgrade' is run is shown below:

------

if conversion fails, you can move this directory back to .bzr
if it succeeds, you can remove this directory if you wish

I have searched around for a solution to this error but have not found one. Any help would be appreciated.

You have two problems:

1.) The format lp:mira is currently in (dirstate-with-subtree) is not compatible with the default format, and "bzr upgrade" doesn't handle that well. Try something like this:

$ bzr upgrade --pack-0.92-subtree

2.) To upgrade the copy on the server, you need to run "bzr upgrade" against it as well:

$ bzr upgrade --pack-0.92-subtree lp:mira

(Note: That may take a while, especially if the branch is large or depending on your version of bzr.)
