on a production site, where I am struggling to update to latest bench, and migrating to python 3.8 following this guide and failing a lot of stuff, then after running bench migrate-env /usr/bin/python3.8 I can run bench commands again on bench 5.8.0, when I run bench update, it only update frappe
frappe@localhost:~/frappe-bench$ bench update --patch
remote: Total 0 (delta 0), reused 0 (delta 0), pack-reused 0
From https://github.com/frappe/frappe
* branch version-13 -> FETCH_HEAD
Backing up sites...
when I update pip install -U frappe-bench and get bench 5.11.0 I cannot run bench command, therefore I downgrade it to 5.10.0 > 5.9.0 > and finally on 5.8.0 I can run bench command again.
Currently installed apps are:
frappe@localhost:~/frappe-bench$ bench version
erpnext 13.34.1
frappe 13.33.1
frappe@localhost:~/frappe-bench$ bench --version
5.8.0
INFO: A newer version of bench is available: 5.8.0 → 5.11.0
additional info: I cannot run bench switch-to-branch version-13 to move away from develop branch and receiving this error.
frappe@localhost:~/frappe-bench$ bench switch-to-branch version-13

Now I am lost. I don’t know which python version is used by bench, cannot update to latest version of bench, and bench seems not detecting ERPNext.
Currently, ERPNext is still running, and users can use it, but I’m afraid things might break unexpectedly in this state.
