Invalid Gitolite Admin SSH Keys

[pallinger]

I installed 4.0.0 on debian buster with redmine 4.0.6 and ruby 2.5.5p157. It seems to be installed ok (although Bootstrap Kit did not work and had to be uninstalled -- maybe that is the problem?), as the /settings/plugin/redmine_git_hosting?tab=gitolite_config_test url does not report any errors, but repository creation and key addition does not seem to work.

In the git_hosting.log, there is the following error when running the gitolite_config_test (but this cannot be seen on the web UI):

2020-02-11 14:49:20 +0100 [ERROR] Invalid Gitolite Admin SSH Keys
2020-02-11 14:49:20 +0100 [ERROR] Failed to authenticate SSH session: Unable to send userauth-publickey request

If I try to add a public key with the redmine admin user, I get the following output in the log:

2020-02-11 14:54:01 +0100 [ERROR] Git exited with non-zero status : 128 : 'sudo' '-n' '-u' 'gitolite3' '-i' 'git' '--git-dir' 'repositories/redmine/project/testing.git' '-c' 'core.quotepath=false' '-c' 'log.decorate=no' 'branch' '--no-color' '--verbose' '--no-abbrev'

Is there any idea what the error could be? Or at least how I could test it better, to get more debug info?

Update: I managed to patch the Bootstrap Kit plugin, so it works, but the error was still the same.

I also managed to find this: ytti/oxidized#1517 (comment)

So it turned out, that I had to convert the ssh private key format with the command:

ssh-keygen -p -m PEM -f /$PATH_TO_KEYS/redmine_gitolite_admin_id_rsa

It would be nice to have it in the documentation that the default private key format in Debian (Just Debian? I highly doubt that.) is not supported, and maybe change the ssh-keygen command in the get_started document to include -m PEM.

Same issue here (Debian 10 buster), @pallinger solution works great, thanks!!

[tsnork]

Thanks for that hint, had the same issue!

[mgagne-champlain]

Very helpful, thanks!! (almost ran out of hairs to pull out over this one :-P)

[connecticus]

Thank you!

Assuming this is either resolved or obsolete.

[angrycuban13]

Not obsolete, it just happened to me on Ubuntu 20.04. You can't just run ssh-keygen and use the default. I had to follow these steps

ssh-keygen -m PEM

I definitely second the idea of documenting this:

Hi @angrycuban13
the installation instruction has been updated with the right key format for ssh-keygen usage. See http://redmine-git-hosting.io/get_started/#step-3-create-ssh-keys-for-user-running-redmine
