So, I upgraded my old RStudio Server installation on my EC2 at Amazon. First step was upgrading RStudio Server. No issues.
Second step was upgrading the R itself. I upgraded the machines R installation to 3.3.2.
EDIT (inserted after comment): I upgraded R by sudo apt-get update && sudo apt-get upgrade. Please also note that which R on the command line gives /usr/bin/R. And that /etc/rstudio/rserver.conf has this line in it; rsession-which-r=/usr/bin/R
When starting R through the command line the version is now 3.3.2. But when logging in to the RStudio Server "web page" it says 3.3.0 at startup (after machine reboot). See dump below.
So, I tried fixing this that the RStudio Server stayed at 3.3.0 while the machines version was 3.3.2. I tried for a few days and found no fix until I simply tried the command version from within RStudio Server. And it strangely answered 3.3.2.
Anyone else understand or seen this behavior before, that it starts up saying that R is at one version, and then actually is a different version when verifying with the version command? And at what version of R is my RStudio Server actually running?
