To resolve this issue, use SSH to connect to the proxy CLI and issue the following commands::
Resetting UI to bound system version...
- Proxy#config t
- Proxy#(config ui) reset
After running these commands, close and re-open your browser windows and then install policy again.
If you have a sysinfo file available (https://proxyIP:8082/sysinfo), you can also check that for a mismatch between the SGOS version and the UI Version - it'll be at the top of the sysinfo, for example:
Blue Coat Systems, Inc., ProxySG Appliance System Information
Title ProxySG Appliance System
Blue Coat Systems, Inc., ProxySG Appliance Version Information
Version: SGOS 18.104.22.168
Release id: 178490
UI Version: 22.214.171.124 (169141)
As you can see, there is a mismatch between SGOS and UI versions. The "Release id" is the build number of the SGOS version, the build number of the UI is listed in brackets behind the UI version number. This also shows that SGOS 126.96.36.199 is newer than SGOS 188.8.131.52 because 184.108.40.206 has a higher build number.
