As we all know, In Debian and Ubuntu desktop operating systems, Software updater tool will notify you whenever a new update is available.

Orphaned (unused) packages are nothing but the packages which will be installed as dependencies/libraries when you install a software in your Linux system.

How To Force Users To Use Strong Passwords In Debian, Ubuntu

A strong password must be comprised of at least 14 characters, including at least one special character, one numerical character, one uppercase and lower case letter. More importantly, passwords shouldn’t be easily predictable and shouldn’t be based on dictionary words. Some non-techie people however will not understand or don’t care about the security. They will keep using easily predictable passwords like pass123, welcome123, Welcome@1 etc., that can be easily broken in few attempts. Also, they won’t change the passwords for ages.
