❌ Failed to cleanly apply 76be83777a964e9e92adbddfe90ef74b6fce079b on top of patchback/backports/1.6/76be83777a964e9e92adbddfe90ef74b6fce079b/pr-305

Ensure you have a local repo clone of your fork. Unless you cloned it from the upstream, this would be your origin remote.
Make sure you have an upstream repo added as a remote too. In these instructions you'll refer to it by the name upstream. If you don't have it, here's how you can add it:
```
$ git remote add upstream https://github.com/pulp/pulp-certguard.git
```

Ensure you have the latest copy of upstream and prepare a branch that will hold the backported code:

$ git fetch upstream
$ git checkout -b patchback/backports/1.6/76be83777a964e9e92adbddfe90ef74b6fce079b/pr-305 upstream/1.6

Now, cherry-pick PR #305 contents into that branch:
```
$ git cherry-pick -x 76be83777a964e9e92adbddfe90ef74b6fce079b
```
If it'll yell at you with something like fatal: Commit 76be83777a964e9e92adbddfe90ef74b6fce079b is a merge but no -m option was given., add -m 1 as follows instead:
```
$ git cherry-pick -m1 -x 76be83777a964e9e92adbddfe90ef74b6fce079b
```
At this point, you'll probably encounter some merge conflicts. You must resolve them in to preserve the patch from PR #305 as close to the original as possible.

Push this branch to your fork on GitHub:

$ git push origin patchback/backports/1.6/76be83777a964e9e92adbddfe90ef74b6fce079b/pr-305

Create a PR, ensure that the CI is green. If it's not — update it so that the tests and any other checks pass. This is it! Now relax and wait for the maintainers to process your pull request when they have some cycles to do reviews. Don't worry — they'll tell you if any improvements are necessary when the time comes!
