Hi all,
Facing same issue with *ERROR weeutil.rsyncupload: Host key
verification failed *error.
However, it's really strange...
I can ssh to remote site as both *root* as well as *pi* user
I can do manual rsync with no problems but weewx builtin rsync returns
above error
At the moment my weewx installation is syncing using cron with no problems
but I want to understand why builtin rsync fails
Problem started after upgrade from weewx 5.0.0 to 5.0.1
Any ideas?
Thank you forward :-)
