Hi Bioconductor Community,

I am new to Bioconductor. I would like to make a R docker container that has a specific version of R (3.6.x). I got the image to spin up and tried to install some Bioconductor packages using BiocManager::install() but it is failing. Please see the output below. I tried looking for other threads and on stackoverflow but there weren't any solutions that seemed relevant to mine. Can anyone provide some help? Greatly appreciate it. Thanks.

BiocManager::install("CytoML")
Bioconductor version 3.10 (BiocManager 1.30.10), R 3.6.3 (2020-02-29)
