Need help to enable autosign

[jaschaezra]

@nebulon I just want to add some screen I just made because I forgot them to create

This is how you'll see it in the repository:

When you take a look at the commit:

The name is set in app.ini

For the key-creation:
It is much easier to do it like this:

gpg --default-new-key-algo rsa4096 --gen-key

then enter the Name, the Email (git@DOMAIN) and NO password!

That's it.

@jaschaezra BTW, you can set a Gravatar/Libravatar for git@DOMAIN and upload e.g. the gitea Logo which then is displayed.

This is odd - after working for a looong time I suddenly get this error when creating a repository and initializing it:

CreatePost, initRepository: initRepoCommit: git commit: exit status 128 - error: gpg failed to sign the data
fatal: failed to write commit object
 - error: gpg failed to sign the data
fatal: failed to write commit object

I first thought that maybe the key is gone. By checking this I found that:

root@0f44f577-d0e0-42e6-a371-d3914aba0014:/home/git# sudo -u git gpg --list-keys
gpg: Fatal: can't create directory '/home/git/.gnupg': Read-only file system
root@0f44f577-d0e0-42e6-a371-d3914aba0014:/home/git# 

I have not changed anything and I do not know when this happened as I was not using my git for the last ~9 months.

Any idea what is going on @nebulon?

Just briefly rereading the thread, did you set GNUPGHOME for git user so it uses the correct (writeable) folder? Seems like the one which is used should be export GNUPGHOME=/app/data/appdata/home/.gnupg

[robi]

@nebulon might be nice to have these set when terminal is launched including HOME.

[jaschaezra]

@nebulon I now get a new error:

root@0f44f577-d0e0-42e6-a371-d3914aba0014:/home/git# sudo -u git bash
git@0f44f577-d0e0-42e6-a371-d3914aba0014:~$ export GNUPGHOME=/app/data/appdata/home/.gnupg
git@0f44f577-d0e0-42e6-a371-d3914aba0014:~$ gpg --list-keys
gpg: WARNING: unsafe permissions on homedir '/app/data/appdata/home/.gnupg'
git@0f44f577-d0e0-42e6-a371-d3914aba0014:~$

[nebulon]

The permissions can be fixed up with:

chmod 600 /app/data/appdata/home/.gnupg/*
chmod 700 /app/data/appdata/home/.gnupg

However, this is also only a warning, not sure if this is the root cause. Are there any keys in the folder itself?

[jaschaezra]

Oh, no, my key is gone. That is odd as I never touched the key after it worked.

[jaschaezra]

After creating a new key and configuring it in app.ini and restarting gitea I still get an error:

root@0f44f577-d0e0-42e6-a371-d3914aba0014:/home/git# sudo -u git bash

Update: Gitea does not get the signing key. The response of https://git.jascha.wtf/api/v1/signing-key.gpg is empty

My best guess is that there are some path poblems - https://docs.gitea.com/administration/signing

[jaschaezra]

Oh, forgot to mention @nebulon

[joseph]

@jaschaezra are your GPG keys password protected ? (See also https://docs.gitlab.com/ee/user/project/repository/signed_commits/gpg.html#gpg-fails-to-sign-data)

@jaschaezra said in Need help to enable autosign:

Update: Gitea does not get the signing key

Did a quick test. Setting GNUPGHOME env var makes it work. You can use CLI tool for this cloudron env set GPGHOME=/app/data/appdata/home/.gnupg . But I think we should set this in the package itself.

[girish]

Well, I am confused. For me, it works out of the box. See this comment from @nebulon - https://forum.cloudron.io/post/55637

• GNUPGHOME is already to /app/data/gnupg
• Just put your keys in above directory
• curl https://gitea.domain.com/api/v1/signing-key.gpg works
• Create empty repo.
