"bzr check" on the repo checked all of the branches inside it (look at
its output -- it should've mentioned them), so it's redundant to check
That rather unhelpful error means that there's nothing to upgrade; it
already is 2a.
Bazaar format names refer to a combination of meta directory (.bzr) +
repository (.bzr/repository) + branch (.bzr/branch) + working tree
(.bzr/checkout) formats. 1.6 and all newer formats use the same branch
format (BzrBranchFormat7); you upgraded the repository and don't have
working trees, so there's nothing else to upgrade.
