R SIG Debian - Nov 2015 - Issues starting RStudio Server and release file expiration under Debian (Jessie)

Hi! I am a new user of Debian and am having an issue loading RStudio Server,
which may or may not be related to a previous 'Release file expiration
error' when trying to perform apt-get update prior to installing r-base into
my remote Debian system.

E: Release file for
http://mirror.optus.net/debian/dists/jessie-updates/InRelease is expired
(invalid since 13d 17h 49min 2s). Updates for this repository will not be
applied.

To work around the release file error I executed the following command which
then allowed R to be installed:

$ sudo apt-get -o Acquire::Check-Valid-Until=false update

I then added this line to etc/apt/sources.list:

deb http://cran.csiro.au/bin/linux/debian jessie-cran3/

Next I added the appropriate key, and performed the above command to update the
system again so R could be reinstalled:

$ sudo apt-key adv --keyserver keys.gnupg.net --recv-key 381BA480
$ sudo apt-get -o Acquire::Check-Valid-Until=false update
$ sudo apt-get install r-base

This gave me the newest version of R. I then installed RStudio, but when I
attempted to access the server from my browser it fails to load.

$ wget https://download2.rstudio.org/rstudio-server-0.99.489-amd64.deb
$ sudo gdebi rstudio-server-0.99.489-amd64.deb

I have attempted to troubleshoot, but from my terminal everything seems to be
okay:

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

debian at r-docs-debian2:~$ which R
/usr/bin/R

I followed the instructions on RStudio support
(https://support.rstudio.com/hc/en-us/articles/200717193), but I believe this
might be a Debian specific problem as I was able to get RStudio working on my
remote instance using Ubuntu vivid using the same/similar commands. I would like
to get RStudio working on a Debian system as I am using the information for some
internal documentation for how to use R and RStudio in the cloud.

Many thanks!

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indeed, mirror.optus.net seems to be outdated.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Therefore, it is a good thing that apt refuses to use the outdated mirror,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.

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,
