After permission denied error on serial port, still says "uploading" and "done uploading"

[php4fan]

Describe the problem

I have connected a Sparkfun ESP8266 Thing Dev board, which apparently is connected to /dev/ttyUSB0.

The documentation says you need to add yourself to the dialout group (and then log out and log in). I tried that, but I got an error saying the dialout group doesn't exist. In other forums I read you need to belong to the group tty, so I tried that and logged out and in.

Still, I get the permission denied error when uploading a sketch. But this report is not about the error per se, it's about the fact that I get the permission denied error in the console, and yet, after that, I also get a progress bar on the bottom right that says "Uploading" and lasts for several seconds, and after that, a balloon that says "Done uploading", with an "i" icon and no error sign, which looks exactly like it has successfully finished uploading. And the sketch definitely hasn't been uploaded.

To reproduce

Upload a sketch

Expected behavior

Either there is an error writing to the port or there isn't.

If there is an error (e.g. Permission Denied), then I should see the error message, and I should not see a message that says "Done uploading".

If I see a message at the very end that says "Done uploading", then it should mean that it has succesfully uploaded the sketch.

Does the permission group for dialout exist for the Manjaro Distro (awesome of course).
For an Arch based distro, maybe sudo usermod -a -G uucp $USER might work?
I'm no IT professional, just a dumb user.

Indeed, that worked and should be added to the documentation.
However, as I said, this report is about the inconsistency between the permission error being shown and the popup still saying "uploading" and "upload done"
