I would like to install the package org.Hs.eg.db version 3.5 in R 3.4.0 and Bioconductor 3.6 (BiocInstaller 1.28.0). I have tried to install the package version 3.4.1, and also tried to use R.3.4.2. The error is always the same, as follows. Any help would be greatly appreciated!

This usually comes up when you are trying to use a network directory for your library path. That's not (IMO) usually worth the effort, so the quick fix is to set your .libPaths to somewhere on your computer's hard drive. An alternative might be to map the directory share to a drive path, like Z:, but like I said, usually not worth the effort...
