Linux clients won't update definitions from SEPM/LUA 12.1.5

I have SEPM 12.1.5 installed. I have couple of linux clients connected to SEPM.

They have old definitions. Before I updated linux clients via unix.sh file, but because I installed offline LUA server and I'm downloading "Avenge MicroDefs25 SavCorp10 Linux Virus Definitions" I expected, that linux clients will be updated via this content. All windows clients are up to date from same source...

Is it a right thinking or I have to still continue with unix.sh file instalation on all linux servers?

Thanks for answer.
