Hello, I am trying to install various packages in my hpc, however none of them are getting installed. I have 3 versions of R on the cluster, and in none of them BiocManager or any other tool is installing.

Code should be placed in three backticks as shown below

# include your problematic code here with any corresponding output

Warning message:

Seurat, liana, none of the packages are available.

A version of this package for your version of R might be available elsewhere,
