I have created a patch. It works for me as intended. I have created it with `git commit -m “…”`and checked with `git format-patch origin` that it contains what I expect. How do I submit the patch? With LibreOffice I would have done `./logerrit submit master`. How to do for CollaboraOffice? I’ve tried with `./cogerrit submit master`, but that does not work. Or could I attach the patch here and someone else will take care of it? ---

Hi @Regina, Please try `./cogerrit submit main`. ---

It results in error > ssh: Could not resolve hostname cogerrit: Name or service not known > fatal: Could not read from remote repository. > > Please make sure you have the correct access rights > and the repository exists. For LibreOffice there is the instruction `https://wiki.documentfoundation.org/Development/gerrit/setup` Perhaps something similar is needed to be able to use `./cogerrit`? ---

This is a DNS/SSH configuration issue — your system doesn’t know what host `cogerrit` refers to. Just like the LibreOffice guide sets up a `logerrit` alias, you need to set up a `cogerrit` alias pointing to Collabora’s Gerrit server. Add to your `~/.ssh/config` file: If you haven’t already, you’ll also need to: 1. **Create an account** on `gerrit.collabora.com` (typically via OAuth/GitHub login). 2. **Upload your SSH public key** to your Gerrit account settings — go to Settings → SSH Keys and paste the contents of your `~/.pub/id_rsa.pub` (or whichever key you use). 3. **Verify the connection** with `ssh cogerrit` — if it’s working, you’ll get a welcome message from Gerrit rather than a “could not resolve hostname” error. After that, `./cogerrit` should be able to reach the remote repository. ---

For the cogerrit thing, then: “./cogerrit setup” guides through the process and outputs what you need at the end, it should be something like: Host cogerrit [gerrit.collaboraoffice.com](http://gerrit.collaboraoffice.com) IdentityFile ~/.ssh/SOMETHING User USERID Port 29418 HostName [gerrit.collaboraoffice.com](http://gerrit.collaboraoffice.com) ---

The long output from `ssh -vvvv cogerrit` contains the text > \*\*\*\* Welcome to Gerrit Code Review \*\*\*\* > > Hi regina-henschel, you have successfully connected over SSH. > > Unfortunately, interactive shells are disabled. > To clone a hosted Git repository, use: > > git clone ssh://regina-henschel@gerrit.collaboraoffice.com:29418/REPOSITORY\_NAME.git Does that mean, that I need to start with this new `git clone` , apply my patch, create a commit and then use `./cogerrit main`? It turned out that `./cogerrit main`does not work, but the above mentioned `./cogerrit submit main ` works 🙂 (What is actually needed instead of `REPOSITORY_NAME`? Found it, has to be `core`)
