### Please describe the problem.
I got into a repository I have not used for a while, and then `datalad` commands failed because annex failed to upgrade it from v5. No details/reason is given at any level making it impossible to figure out for a user what to do/try next:

note that `info` works out without failing to upgrade with that older version.
and indeed somehow I have:
[[!format sh """
$> ls -ld ../.git/info/attributes
-rw-r--r-- 1 root yoh 39 Jun 5 2009 ../.git/info/attributes
$> find .git -uid 0

"""]]
fixing ownership and rerunning upgrade worked (older version was remained used):
[[!format sh """
$> git annex upgrade
upgrade (v5 to v6...) (scanning for unlocked files...)
(v6 to v7...) ok
"""]]
So it seems git-annex should revert back to reporting errors from underlying `git` invocations to make it possible to debug such cases
