Hi there, I'm having issue with conda activate. The problem came after I installed locally R package that I dowloaded from bioconda and now after conda activate my_env on HPC cluster it give this:

This package can only be used in conda-build
Connection to clusterxxx is closed.

any suggestions? Many Thanks

@alikhuseynov Please open another issue following the template provided for bugs. Your environment contains a package not meant for end-users, hence the error, but we need more details to know which (hence why I suggest following the bug template for new issues). Thanks!
