Conda failing to install VEP

Question

[michael.flower.14]

I'm trying to install VEP in a conda environment, but it keeps failing. I've tried with the normal installation process:

conda install -c bioconda ensembl-vep 

But get the below errors which run for about an hour and eventually fail:

$ conda install -c bioconda ensembl-vep
Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.
Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.
Collecting package metadata (repodata.json): done
Solving environment: | ^[failed with initial frozen solve. Retrying with flexible solve.
Solving environment: - 

I've also tried creating a new environment and installing, but still fail.

conda create -n ensembl-vep -c conda-forge -c ensembl-vep 

Any more ideas anyone??

$ conda install -c bioconda ensembl-vep

Have you tried to use mamba? Usually it solves conda problems

【bioconda】The channel is not accessible or is invalid.

Awesome, that’s worked! A load off my shoulders, thank you!
