I’ve tried to upgrade freepbx 10.13.66-22 to SNG7 via upgrade RPM distro-upgrade-1807-2.sng7.noarch.rpm
distro-upgrade told me all prerequisites passed. Seconds before the first reboot i received several PHP error messages. After the upgrade was finished, the error message "call to undefined method modulelist::get() in /var/lib/asterisk/bin/fwconsole on line 74 appears in the CLI.
57 modules was broken, no way to reinstall the modules with fwconsole or amportal. I had to restore the VM from a backup. How can i avoid this error next time?
