Hi Dominic,
This means that the version of AiiDA that you ran the current
profile with is newer compared what is currently installed, and the
config file is not compatible.
Since your config file has version 8, it seems you installed AiiDA
v2.0 and then switched back to an older version.
To use your config again, you should install AiiDA v2.0 again and it
should work.
If you really need to use an older version again with that profile.
you still have to install v2.0 first and then you can try to
downgrade the config with `verdi config downgrade 5`.
Then you immediately reinstall the older version of AiiDa that you
want (careful, running any `verdi` command will automatically
upgrade the config again).
Note that if you already migrated your database, there is no way
back and you cannot use the older version of AiiDA.
You would have to restore it from backup.
Hope that helps,
Sebastiaan
P.S. The warning you can ignore, it is just a deprecation warning
coming from `paramiko` that is calling a deprecated resource from
the `cryptography` module.
There is an option issue on paramiko to address this :
