I want to upgrade to Bioconductor 3.6. I followed the instructions to upgrade R (I have 3.4.2), and source("https://bioconductor.org/biocLite.R"). However, it shows 3.5 still. Running biocLite() does not change this. 

I tried removing the biocInstaller package as was suggested by some, but that did not get me to 3.6
