Again, after sucessfull updates i see on my 2 Servers (Ubuntu Server 16.04) again errors in the syslog file that the update was not sucessfull. With manually started updates from the shell ./esets_update --verbose i get on both that 3 files are corrupted, after i got the updates fixed in the night after several times of manually start the update from the shell (./esets_update) - on both servers!
As both servers are located in different data centers i believe your update files or servers are the reason, there is no proxy or something between my servers and the update servers. Over time it'
