Crash after restarting Tribler

[qstokkink]

Starting the second time after starting Tribler with a fresh configuration.json, Tribler keeps crashing.

I found a workaround that doesn't require me to delete my configuration every time: setting http_port_running to 0 after shutting down Tribler.

@qstokkink

i still get the same error from the git main branch.
i am running arch btw :)

@hbiyik Thanks for testing! I want to revive Arch support in the next minor 8.1.x releases (#6740, #6739), and also proper multiplatform releases in general (#8171, #5345, #5327) using GitHub Actions: I've been going through your buildsys repository again 🙂 Anyway, for now, disclaimer: Arch may be a bit of a rocky experience.

It looks like you didn't perform the npm run build step, step 3 of the docs. Is that correct?

[hbiyik]

i hadnt done the npm build, but after building the ts still get the same error. May be i should just put some debugger in it.

PS: that buildsys should be quite irrelevant now but the ideas might in it might live on.

[qstokkink]

If you want to debug this, the following line looks for the dist folder and puts you in "developer" mode if it cannot be found:

tribler/src/tribler/core/restapi/webui_endpoint.py

Lines 28 to 29 in 417ce08

	self.has_dist = (self.webui_root / "dist").exists()
	self.session = ClientSession() if not self.has_dist else None

The webui_root is defined here:

tribler/src/tribler/__init__.py

Line 14 in 6b1b640

return pathlib.Path(__file__).parent.absolute() / "ui"

Normally, this should be looking for src/tribler/ui/dist. You could try using my dist (built for commit ca82531) and putting it in that directory:

dist.zip
