Hi,

I'm trying to install DESeq2 on my R-server (vers. 3.6.1), and it fails with :

> BiocManager::install("DESeq2")
Erreur : .onLoad a échoué dans loadNamespace() pour 'BiocManager', détails :
  appel : NULL
  erreur : Bioconductor version '3.8' requires R version '3.5'; see
  https://bioconductor.org/install

I first did what explained at : https://bioconductor.org/install/
if (!requireNamespace("BiocManager", quietly = TRUE))
    install.packages("BiocManager")

Am I missing something ?...

Thank for your help Regards E.T.

You have a version of the package 'BiocVersion' installed from a previous R installation; probably you updated R but re-used the old library. Please see the BiocManager vignette on options to use a separate library for your new R installation (recommended) or update all packages to the version of Bioconductor appropriate for your version of R.
