I wanted to upgrade to version 3.0.0.8 and it failed after the backup step with an SSL CA Error:
Starting update to E.F.A. 3.0.0.8

All done
If your system does not return to a command prompt
you can now safely press ctrl-c to abort logsave
Thank you for using E.F.A.
Can anyone help? I'm pretty bad with Linux
