bit crashes on startup (trying to get keyring) #1784

Closed s-light closed 4 months ago

s-light commented 4 months ago

bit fails to start with a TypeError: expected string or bytes-like object, got 'NoneType' seems it can somehow not really access the keyring..

in the past (i think before i upgraded my system) it just worked ;-)

console command backintime-qt --debug:

seems this error is thrown by something at https://github.com/bit-team/backintime/blob/ba50bf9c197a5469abfa53fd017dc15bf8a113b6/common/tools.py#L1281

on more reading i found the keyring-config thing and with this found that the problem is the keyring library itself:

so maybe its better to report it there.... (please let me know!)

Hello Stefan,

Thank you for taking the time to report the bug and providing the details. I appreciate your feedback.

How do you installed BIT? From Ubuntus official repo?

I am not sure but it seems you installed keyring from PyPi. It might be that it shadows the keyring package installed from the official Ubuntu repos. Please check pip list | grep -i keyring. If there is one please uninstall it via pip uninstall keyring.

Best regards,

s-light commented 4 months ago

you are correct - i did install via offical ubuntu package.. (or at least i think so .... its about a year ago..)

and indeed there is keyring installed via pip...

$ pip list | grep -i keyring

keyring                 24.3.1

but if i try to deinstall:

pip uninstall keyring

i get the wounderfull magic warning :-)

so i did searched a bit more..

so no change.. but i will do a restart and see if maybe this helps..

s-light commented 4 months ago

restart did not fix it.

the pip version is listed again. and if i do 

$ pip show keyring

i currently have no idea how to track this down any futher -

maybe deinstall bit and then try to narrow it down...

buhtz commented 4 months ago

Can you reproduce the error without BIT using this line?

python3 -c "import keyring;print(keyring.get_keyring())"
s-light commented 4 months ago

apt bit uninstall did not removed the python3-keyring package.

TypeError: expected string or bytes-like object, got 'NoneType'

so yeah - the error is not BIT specific!

thanks buhtz for your time!!!

i think i have to move this to the python-keyring repository...

buhtz commented 4 months ago

Report the problem to the original/upstream keyring author please. Also remove your pip-version of this package via pip uninstall keyring. Then BIT again will use the package from Debian repo installed via apt install python3-keyring.

thanks! i will post the issue there.

just for the completeness:

$ pip uninstall keyring

so this package is the debian one..

whatever did the trick i do not know - i thikn it has to do with the shown warning about ptxconf maybe...

thinks i did:

at least - it is now working again!
