The lock file './db/lockfile' already exists. There might be another instance with the
same database dir running. To avoid locking overhead, only one process
can access the database at the same time. Do not delete the lock file unless
you are sure no other version is still running!
There have been errors!

Several instances of reprepro operate concurrently on the very same repo:

https://github.com/stackforge/fuel-main/blob/master/mirror/ubuntu/module.mk#L50
https://github.com/stackforge/fuel-main/blob/master/packages/deb/module.mk#L59

The dependencies of repocleanup.done target are messed up (which proves that injecting locally built debs into the mirrored
repo is a *BAD* idea)

    packages/deb: fix target dependencies so make -j works again

    Both repocleanup.done and reprepro.done targets
     - modify the local copy of MOS repo (which is a bad idea),
     - depend on ubuntu/mirror.done target

    As a result two instances of reprepro try to concurrently modify the same
    APT repo (which fails). Make repocleanup.done depend on reprepro.done to
    avoid the problem.
