### Please describe the problem.

I get this error when trying to copy annexed files from my laptop to the bare repository on my server:

    anarcat@angela:ohm2013$ git annex copy -t origin .
    git-annex: cannot determine uuid for origin

### What steps will reproduce the problem?

Here's my setup:

 * `angela`: regular git repository on my laptop (`angela`) where i ran `git annex init` and `git annex add`ed 4 big files (in `~anarcat/presentations/ohm2013`)
 * `marcos-bare`: a bare git repository where i ran `git annex init` on a different server (`marcos`) (in `~anarcat/repos/presentations/ohm2013.git`)
 * `marcos-checkout`: a checkout of the above repository on marcos (in `~anarcat/presentations/ohm2013`)

I ran `git pull/push` everwhere in there, and still get the error.

Remotes on all repos:

 * `angela`: `origin  anarcat.ath.cx:repos/presentations/ohm2013.git`
 * `marcos-bare`: no remote
 * `marcos-checkout`: `origin  /home/anarcat/repos/presentations/ohm2013.git`

Note that file added with `git annex addurl` on `marcos-checkout` properly gets propagated on `angela` once i do `git annex get` there.

### What version of git-annex are you using? On what operating system?

`angela` runs:

[[!format txt """
git-annex version: 4.20130730-ge59a8c6
build flags: Assistant Webapp Pairing Testsuite S3 WebDAV Inotify DBus XMPP DNS
local repository version: 3
default repository version: 3
supported repository versions: 3 4
upgrade supported from repository versions: 0 1 2
"""]]

I was able to reproduce with the backport version too.

I compiled it by hand from git.

`marcos` runs:

[[!format txt """
git-annex version: 3.20120629
local repository version: unknown
default repository version: 3
supported repository versions: 3
upgrade supported from repository versions: 0 1 2
"""]]

### Please provide any additional information below.

In addition, there's this error on `marcos-bare`:

### Workaround!

I found that I could succesfully push to the non-bare repo, like this:

[[!format txt """
anarcat@angela:ohm2013$ git remote add marcos-checkout ssh://anarcat.ath.cx/~/presentations/ohm2013
anarcat@angela:ohm2013$ git fetch marcos-checkout
From ssh://anarcat.ath.cx/~/presentations/ohm2013
 * [new branch]      git-annex  -> marcos-checkout/git-annex
 * [new branch]      master     -> marcos-checkout/master
anarcat@angela:ohm2013$ git annex copy AlerteRouge.webm --to marcos-checkout
copy AlerteRouge.webm (checking marcos-checkout...) (to marcos-checkout...)

[...]
"""]]

It seems that git-annex doesn't like bare repos at all...

### Fix

It seems that my problem was specifically related to [[bare repositories]], which are not well supported historically. There has been other reports of problems in the past, which I missed in my search because symptoms were different:

 * [[bugs/bare git repos]]
 * [[forum/get and copy with bare repositories]]

Yet while I was able to do `git annex get --all` *from* the `marcos-bare` repository, I still get the original error message while trying to `git annex copy -t marcos-bare`, which is pretty annoying considering the original files are on my laptop, which is not publicly accessible. So I basically need to add the `marcos-checkout` as a remote, copy there, then get from the bare repo to make this work, which is a rather convoluted way of doing things. :)

It seems to me a proper fix would be to be able to `git annex copy --to marcos-bare`. Thanks!

Update: it seems te problem was that I had the following in my `.git/config`:

    [remote "marcos-bare"]
            url = ssh://anarcat.ath.cx/~/repos/presentations/ohm2013.git
            annex-ignore = true
            fetch = +refs/heads/*:refs/remotes/marcos-bare/*

I have *no* idea how that `annex-ignore` got there, but that was the root of my problem. Removing it it allowed my to do `git annex copy`. I really don't know how this happened, but I guess this is [[done]], although I believe this error message is really confusing and could be improved.
