git-annex/doc/bugs/gcrypt_repository_not_found.mdwn

### Please describe the problem.

I seem to be incapable of creating an encrypted git-annex repository with the instructions provided at [[tips/fully_encrypted_git_repositories_with_gcrypt/]]. The setup step fails with *gcrypt: Repository not found: (path-to-repo)*.

### What steps will reproduce the problem?

I *think* I naively followed the tips page, but I might be wrong. Here's the minimal reproducer I could find, but originally the problem occured with an SSH remote which I thought was the culprit.

    git init a
    git init --bare b
    cd a
    git annex init
    echo > foo
    git annex add foo
    git commit -m'test repo' 
    git annex initremote encrypted type=gcrypt gitrepo=~/tmp/b keyid=8DC901CE64146C048AD50FBB792152527B75921E


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

This is Debian stretch with backports, so git-annex is actually from backports (6.20180509-1~bpo9+1):

git-remote-gcrypt is the vanilla version from stretch (1.0.1-1) but the bug can be reproduced with the 1.1 version from sid.

Note that this failure leaves the repository with an half-configured remote. Trying to rerun the setup gives this error:

    git-annex: There is already a remote named "encrypted"

Removing the remote seems to be sufficient to restore a working state and try again:

    git remote rm encrypted

I also note that the `encryption step` part takes a looong time when we try to reproduce the issue multiple time... I will report this in a separate issue.

### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)

Of course! As you very likely know, I use git-annex daily and I'm a really happy user. :) This is, however, the first time I give gcrypt a shot.

Thanks for your hard work! --[[anarcat]]

Update: turns out this is a bug in git-remote-gcrypt and this probably doesn't need to be tracked in git-annex. the workaround is to comment out the `push.sign=ifAsked` entry in the git config, or to make git-remote-gcrypt ignore unknown options. so [[done]].  --[[anarcat]]
