Recovered successfully, but blitzapi still failing as the cl-grpc was not installed:

needs to be part of the recovery and the blitz api install as well.

After running:

config.scripts/cl-plugin.cln-grpc.sh on mainnet
sudo systemctl restart lightningd

manually the blitzapi and weUI is up.

@rootzoll @fusion44 the blitz_api installation errors are fixed by #3171 and https://github.com/fusion44/blitz_api/pull/119, but will need a new build after they are merged.

(Before the recovery is started the blitzapi.service should not be dependent on the /home/bitcoin/.lightning/bitcoin/ca.pem for two reasons:

• the symlink to the SDcard is not created yet
• the cln-grpc plugin is not installed in previous versions)

Good news: the recovery was able to start after a the blitzapi installation was fixed (manually) !

I feel we should word this a bit better:

Would you like to start the update and recovery process?
