Bench commands not running in frappe-bench folder

After upgrading Ubuntu to 20 from 18 I’m getting a weird situation. If I run bench src from the home folder ~, it seems to run, but bench update says it isn’t in the right folder. . If I cd into frappe-bench I get errors with any bench commands.

frappe@ubuntu:~$ bench src
/home/frappe/.local/lib/python3.8/site-packages
frappe@ubuntu:~$ cd frappe-bench/
frappe@ubuntu:~/frappe-bench$ bench src
Could not find platform independent libraries

same issue here. any idea?

I had to put the Ubuntu 20 VM on the shelf and keep using 18 with version 12. A spinoff of that has been updated to 13 after some effort.

Try to get your python to 3.9 , and run bench migrate-env python3.9. I’ve been reinstalling alot of python/pip apps, run pip3 install --upgrade frappe-bench with sudo as well. That has at least got me to the point where I have a somewhat operable bench in ~/frappe-bench but getting mariadb , redis and other requirements set up is taking more time than I have been able to spend on it.
