I have a case where `whereis` knows that a file is present in an exporttree
remote, but `get` fails:
joey@darkstar:/tmp/bench/repoclone>git annex whereis bar
whereis bar (1 copy)
b1a73a91-5f79-4b4b-b838-683e602b2888 -- joey@darkstar:/tmp/bench/repo
The following untrusted locations may also have copies:
163219a6-fdc1-4d3e-98a6-7aed3e9d605d -- [dir]
ok
joey@darkstar:/tmp/bench/repoclone>git annex get bar
get bar
Unable to access these remotes: dir
Try making some of these repositories available:
163219a6-fdc1-4d3e-98a6-7aed3e9d605d -- [dir]
b1a73a91-5f79-4b4b-b838-683e602b2888 -- joey@darkstar:/tmp/bench/repo
failed
git-annex: get: 1 failed
- exit 1
Reproducible with git-annex 7.20181106-g58d1b2510 using this script.
It looks like the export database is not getting updated to reflect the
export that was made in the other clone of the repository.
