Description

Short Story

I can connect to my Gitea Server through the git-cli using HTTP, but SSH connections do not work.

Long Story

I am running gitea as a service using a service file /etc/systemd/system/gitea.service with the following content:

[Unit]
Description=Gitea (Git with a cup of tea)
After=syslog.target
After=network.target
[Service]
# Modify these two values and uncomment them if you have
# repos with lots of files and get an HTTP error 500 because
# of that

The other configuration file at /etc/gitea/app.ini looks like this:

APP_NAME = Gitea: Git with a cup of tea

I am able to check out my repo using HTTP connections like this:

myuser@myhost ~/workspace/somerepo $ git remote set-url origin http://12.34.45.56:3000/something/somerepo.git
myuser@myhost ~/workspace/somerepo $ vim .gitignore 
myuser@myhost ~/workspace/somerepo $ git add .gitignore 
myuser@myhost ~/workspace/somerepo $ git commit -m "testing http push"
myuser@myhost ~/workspace/somerepo $ git push origin master

To http://myhttpuser:[email protected]:3000/something/somerepo.git
   a90b3c3..4cc65e9  master -> master

But when I switch my remote address to ssh I get an error:

myuser@myhost ~/workspace/somerepo $ git remote set-url origin ssh://[email protected]:2222/something/somerepo.git
myuser@myhost ~/workspace/somerepo $ GIT_SSH_COMMAND="ssh -i /home/myuser/.ssh/my_id_rsa -p 2222 -l git -vvv -E /home/myuser/Documents/gitea_ssh_debug.log" git fetch -v
fatal: '/something/somerepo.git' does not appear to be a git repository
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.

The above command produces a logfile (/home/myuser/Documents/gitea_ssh_debug.log) for the ssh connection made by git and the output of it reads like this:

OpenSSH_7.2p2 Ubuntu-4ubuntu2.6, OpenSSL 1.0.2g  1 Mar 2016
debug1: Reading configuration data /home/myuser/.ssh/config

So my interpretation of this debug-log is, that the ssh connection is established correctly, because when I connect manually with ssh I can log in:

myuser@myhost ~/workspace/somerepo $ ssh -p 2222 -i /home/myuser/.ssh/my_id_rsa -v [email protected]
Welcome to Ubuntu 18.04.1 LTS (GNU/Linux 4.15.0-39-generic x86_64)
git@my-remote-host:~$

As you can see i have already tried to give the git-cli some information about the ssh connection like ssh key to use.
I think the Gitea-Server lacks some crucial piece of configuration, but I cant find out which.

I tried already giving the git-cli some information as you can see in the commmand using the environment variable GIT_SSH_COMMAND.
Then I also with the Gitea-Gui in Settings->SSH keys I added the SSH keys that I use for the plain ssh connection, but of no avail.

Has someone had similar problems and knows how to fix it?

[lunny]

I think change sqlite path with an absolute path maybe fix your problem.

PATH     = data/gitea.db

PATH     = data/gitea.db 

I set the Path in app.ini to /var/lib/gitea/data/gitea.db.

Restarted the Service service gitea restart.

Still the same error.

Additionally I checked that the git user has the correct access rights on that Path:

root@gitea-host: ~/# ls -all /var/lib/gitea
total 28
drwxr-xr-x  7 root root 4096 Nov 18 21:45 .
drwxr-xr-x 78 root root 4096 Nov 18 21:45 ..
drwxr-xr-x  2 root root 4096 Nov 18 21:45 custom
drwxr-x---  3 git  git  4096 Nov 20 22:14 data

drwxr-x---  3 git  git  4096 Nov 21 00:03 log
drwxr-xr-x  2 root root 4096 Nov 18 21:45 public

It seems there is no problem with access right.

If gitea want to modify custom/app.ini? Maybe you could change custom's owner to git and retry.

I did a chown -R git:git /var/lib/gitea.

Which makes ls produce:

ls -all /var/lib/gitea
total 28
drwxr-xr-x  7 git  git  4096 Nov 18 21:45 .
drwxr-xr-x 78 root root 4096 Nov 18 21:45 ..

drwxr-x---  3 git  git  4096 Nov 22 13:40 log
drwxr-xr-x  2 git  git  4096 Nov 18 21:45 public

Restarted my service: service gitea restart .

But still i get the same error over ssh.

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs during the next 2 weeks. Thank you for your contributions.

@keltik85 the SSH path needs to be absolute or relative to the home directory for user git, so try this instead:

ssh://[email protected]:2222/~/gitea-repositories/something/somerepo.git

[lunny]

I will close this one, please feel free to reopen it.
