Failed downgrade to 1.8.2

Get Help
1

Hi after an unsuccesfull downgrade i get stucked in a dwongrade on one of my octoprint instances on ubuntu.

I followed the installation this guide:
https://makenotes.de/2020/03/octoprint-on-ubuntu-using-python3-and-systemd/

I tried a "pip install --force-reinstall https://github.com/OctoPrint/OctoPrint/archive/1.8.2.zipl" because i had that loggin problem with 1.8.3

but this instance fails now at startup:

Sep 27 15:17:06 Ph-3D-Druck systemd[1]: Started OctoPrint (instance 2) - Open Source Printing Interface for 3D Printers.

Are you sure you are installing 1.8.2 into your OctoPrint instance's virtual environment? You haven't mentioned activating the venv anywhere. The setup guide you linked sounds like you'd need to do this:

source /home/octoprint/python_venvs/octoprint2/bin/activate
pip install --force-reinstall OctoPrint==1.8.2

What is "that login problem with OctoPrint"? Where's the bugreport? Where's the support ticket?

Also, I just released 1.8.4 that fixed some issues properly reported to me, maybe you are in luck and it solves yours as well.

right. I did it in the venv like mentioned in the guide.Sorry to bother again - but how do i upgrade to 1.8.4 ? It woul like to give it a try.

Now it seems like 1.8.3 is running again - but i have the issue again, that i can not login. Above that there seems to be a problem with the packages....:
