System: Linux Mint 19 Cinnamon 64-bit, based on Ubuntu 18.04.
RKHunter: packaged version 1.4.6-2.
Unfortunately, when I try to update its database, I get error:
$ sudo rkhunter --update [ Rootkit Hunter version 1.4.6 ] Checking rkhunter data files... Checking file mirrors.dat [ Skipped ] Checking file programs_bad.dat [ Update failed ] Checking file backdoorports.dat [ Update failed ] Checking file suspscan.dat [ Update failed ] Checking file i18n versions [ Update failed ] Please check the log file (/var/log/rkhunter.log)
I checked the log with no real result.
