Snap Package is broken

[sruehl]

When running the package from the snapstore following error occurs:

❯ opcua-client
Traceback (most recent call last):

was already reported here but ignored: #93

snap was installed from https://snapcraft.io/opcua-client

That package is outdated. I created it once with one click using some snap/github integration, but never found out how to update it later... and I tried several times and I have a Phd in a supposedly relevant field ;-(

[oroulet]

so if you know how to do that, you are welcome to try or explain here...

[sruehl]

No idea, but as a naive approach I would try to setup a action with https://github.com/marketplace/actions/snapcraft-action and limit it to on: tags. Do you remember where you exactly struggled or what the problem was?

[sruehl]

Actually I think it might be better to use the official actions https://github.com/snapcore/action-build and https://github.com/snapcore/action-publish.

[sruehl]

Here is a bit more complete example https://snapcraft.io/docs/ros-with-github-actions.

I could prepare a PR but can't help debugging if I'm not able to see the run output (might be restricted to crontributer only)

[sruehl]

so TLDR: you need to to create a Github secret called STORE_LOGIN and fill it with the output as described here https://github.com/snapcore/action-publish#store-login.

Once that is done you can merge the PR and we check from there what needs to be done.
