ImportError: cannot import name Markup from flask

[lavitiy]

Since Flask is using Jinja2 for quite some time, they removed the re-export of Markup with the 3.0.0 release

1. Edit file /home/gramazeka/switchmap-ng/switchmap-ng/etc/config.yaml with correct SNMP parameters and then restart the daemons.
2. You can restart switchmap-ng daemons with these commands:
   $ bin/switchmap-ng-cil restart api
   $ bin/switchmap-ng-cli restart poller
3. Switchmap-NG will not automatically restart after a reboot. You need to re-install as the "root" user for this to occur.

[maxferrario-msf]

I have the same error, and the same OS (Ubuntu 22.04.3 LTS).
The only (minor?) difference is that in my case the error message refers to the file lib/python3.10/dist-packages/flask/init.py
