Restart the IPS service manually from System Services | Services | IPS and then try "Update Pattern Now" from Back & Firmware | Pattern Updates. Alongside, please DM us the following logs and if anyone has a registered case# with the Support Team. Please refer, Sophos Firewall: Where to find log files.
1. u2d.log
2. csc.log
3. Start debug log for IPS service before capturing the ips.log
Just to add that Avira and Sophos patterns failed to updated. I restarted the system, and moved the U2DVERSION file to U2DVERSION_old under /content/avira and Avira updated successfully (because a new pattern was available).
The same trick did not work for savi, because there are no other new pattern. I will try tomorrow.
Sophos you should provide a way to force the download of the package in some way. Using commands, procedure of whatever. I formatted the XG and the behaviour is the same with pattern update process.
