Hello, I'm very much a novice when it comes to R and I have never used BiocManager and am having some issues installing some things. I've been given a script to use for some filtering and one of the steps requires me to install BiocLite (see first command). As you can see by the error it's telling me that BiocLite is not available for the version of R I'm currently using. I've tried using R 3.6.2, R 4.0.0 and R 4.0.2 and a couple of the newer versions of Bioconductor but all of them give me the same error (with different versions obviously). The error message and command, as well as session info, are pasted below.
