How do I update a single package? As far as man apt-get says apt-get upgrade doesn't take a package/list of packages as parameter:
upgrade
upgrade is used to install the newest versions of all packages currently installed on the system from the sources enumerated in
/etc/apt/sources.list. Packages currently installed with new versions available are retrieved and upgraded; under no circumstances are currently installed packages removed, or packages not already installed retrieved and installed. New versions of currently installed packages that cannot be upgraded without changing the install status of another package will be left at their current version. An update must be performed first so that apt-get knows that new versions of packages are available.

install is followed **by one** or more packages desired for installation or upgrading, If you have a better answer, you can answer the question.It would be great. – Binarylife Aug 04 '11 at 11:56apt-get install --only-upgrade <packagename>will not install any new packages – taneli Oct 15 '12 at 11:29installcommand upgrade also the dependencies of that single package if necessary? – Pino May 31 '13 at 08:18installis the right command for this, even if it seems counter-intuitive. – Matt Dodge Aug 22 '13 at 19:57apt install --only-upgrade install <package>– Nasik Shafeek Sep 07 '16 at 03:09--only-upgradeis useless here.installsolely will upgrade the package – Anwar Nov 01 '16 at 07:03apt 1.0.1), upgrading a package usingapt installdoes not affect theautomark, whether--only-upgradeis supplied or not. Though of course using--only-upgrademakes sense if you don't want to accidentally install something new. It will also upgrade any required dependencies. – dualed Aug 23 '18 at 13:01--only-upgradeflag ensures the package isn't set to manually installed (Ubuntu 20.04) – Fadi Feb 05 '22 at 17:12
