I got a new computer and re-installed Rstudio with R version 4.2.0. I am using BiocManager version 1.30.18. I already had a R code written for DESeq2 in the older computer so I tried using this and found that I cannot seem to install DESeq2 using the BiocManager.

Here is the code I used.

if (!require("BiocManager", quietly = TRUE))
    install.packages("BiocManager")
BiocManager::install("DESeq2")

Here is the error I get.

'getOption("repos")' replaces Bioconductor standard repositories, see '?repositories' for details

I know for sure that DESeq2 package for R 2.4.0 is in bioconductor 3.15. I have also read that bioconductor 3.15 is the correct version for R 2.4.0. So I don't understand why this is not installing.
From reading other posts, it seems I am not the only one having the same issue but there does not seem to be any reply to these posts asking for help on this other than "try again later". Please advise.

Thanks.
