Make sure you have the latest FOS Linux kernel -> Web UI->Fog Configuration-> Kernel update. You will want 5.10.x series of kernels for both x64 and x32 systems.
Lastly you can update to the dev branch (suggested if you need to deploy Win10 20H2 or later versions of windows) to get the fixes for those OS’) all you need to do is change into the git repository you downloaded then do the following:
git pull git checkout dev-branch git pull cd bin ./installfog.shThat will update your fog install to the pre-release version of 1.5.10. That release is stable and will most likely be what 1.5.10 will be released as.
Now when 1.5.10 is released you will need to switch back to the master branch this way.
git pull git checkout master git pull cd bin ./installfog.sh
