Dear Kelly,

indeed, mirror.optus.net seems to be outdated.  Compare for instance with Debian's
primary australian mirror:

Therefore, it is a good thing that apt refuses to use the outdated mirror,
because if no action is taken and if the mirror does not recover, you will
eventually to miss updates for important bugs, etc.

By setting Acquire::Check-Valid-Until=false, you have allowed apt to use an
outdated mirror.  However, it would be better to switch to an equally fast one,
that is up to date.

Anyway, the problems you encounter later are not caused by the outdated mirrror.

> $ wget https://download2.rstudio.org/rstudio-server-0.99.489-amd64.deb
> $ sudo gdebi rstudio-server-0.99.489-amd64.deb
> 
> debian at r-docs-debian2:~$ sudo rstudio-server verify-installation
> debian at r-docs-debian2:~$ sudo rstudio-server restart
> debian at r-docs-debian2:~$ sudo rstudio status
> sudo: rstudio: command not found

rstudio.org provides Debian packages for RStudio server and for RStudio desktop.
You installed the rstudio-server package, and it does not provide the rstudio
command, which is in the rstudio package.

$ dpkg -L rstudio-server | grep bin/rstudio$
(no output)

$ dpkg -L rstudio | grep bin/rstudio$
/usr/lib/rstudio/bin/rstudio

Have a nice day,
