Hi,
I encountered the following errors since 3 December 2017 with ESET Nod32 (version 4.0.85) on Ubuntu 16.04.3 LTS (4.10.0-40-generic #44~16.04.1-Ubuntu SMP). Laptop model HP Pavilion 14-bf057tx
ESET Daemon Cannot initialize scanner: Module init (Note: NESET Daemon will not load after reboot and I need to reinstall NOD32)
ESET Daemon Error updating Antivirus modules: File corrupted.
ESET Daemon Error updating Antivirus modules: Unidentified server response.
ESET Daemon Cannot read from socket: Connection reset by peer.
ESET Daemon Error updating Antivirus modules: File not found on server.
After repeated reinstallation attempts, NOD32 is still showing incorrect database version (see attached screenshot).
I noticed that NOD32 is trying to download a large file (31 – 80 MB) during each update attempt. I last successfully updated NOD32 on 29 November 2017.
After 2 successful update attempts on 5 December 2017, I suddenly encountered the “ESET Daemon Cannot initialize scanner: Module init” error. After rebooting, ESET Daemon was unable to startup. Subsequently, I was unable to update the database despite multiple reinstallation attempts.
I tried the following:
Installed libc:i386 and uninstalled libc-i386
Uninstalled NOD32 using the default uninstaller (esets_gil)
Reinstalled NOD32 using the installer downloaded from ESET website (eset_nod32av_64bit_en.linux)
Manually removed the em*.dat files from /var/opt/eset/esets/lib before updating the database.
Manually moved the em*.dat files from /var/opt/eset/esets/lib to another folder before updating the database.
Previously, I encountered read-only file system error with /var/opt/eset/esets/lib. I used a Live USB to boot the system, unlocked and mounted the encrypted volume, switch to chroot and remove the em*.dat files from /var/opt/eset/esets/lib and restart.
Appreciate your advice. Thanks.
