I saw this snippet in some installation instructions:

$ apt-get install update

I know what apt-get install XXXX does and I know what apt-get update does, but I can't find any info on what this combined statement does. What does it do?

There is no command like this:

$ apt-get install update
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package update

Any arguments given after install will be taken by apt-get as a package name. But since there is no package update, it will fail.


It attempts to install the package named "update".


As far as I know there in no package called update which the command apt-get install update should install.

May be they meant apt-get update which updates the apt cache.
