I'm trying to ugrade Bioconductor 3.5 to 3.5 using:

biocLite("BiocUpgrade")
Error: Bioconductor version 3.4 cannot be upgraded with R version 3.4.0

Why? I have R 3.4.0

Remove (all copies of) BiocInstaller and source("https://bioconductor.org/biocLite.R"). This should provide you with BiocInstaller version 1.26.0; use biocValid() and biocLite(ask=FALSE) to update packages.

Thanks for answer, I removed all R and all libraries and I installed everything from beginning. Now I have Bioconductor 3.5.

Thanks, problem solved!
