Im currently trying to install Creality 2x temperature reporting fix but i always get this mesage :
ERROR: Invalid requirement: 'pip install "https://github.com/SimplyPrint/OctoPrint-Creality2xTemperatureReportingFix/archive/master.zip"'Hint: It looks like a path. File 'pip install "https://github.com/SimplyPrint/OctoPrint-Creality2xTemperatureReportingFix/archive/master.zip"' does not exist.Fehler!Could not parse output from pip, see plugin_pluginmanager_console.log for generated output
I tried installing with the URL link and the search in the pluginmanager.
Install it via the plugin manager in the settings menu of the OctoPrint webinterface 
I did
I also tried installing it from my computer some minutes ago but still wont work
Alrighty
Then please upload a systeminfo bundle 
That's odd, pip is being called with --process-dependecy-links
which hasn't been supported since 19 from what I can find on google. It's also specifying the install command twice, which is causing more of the error messages.
I´ll just reinstall Octopi mabye this will work...
Dependency links can be checked/unchecked in OctoPrint's plugin manager settings - the little wrench in the top right of the plugin manager window. But yeah, last I remember pip dropped support for that quite a while ago.
