I'm having issues with using the

untar

module in setup with nf-tests with NCBI's taxdump as the input file for the taxonkit/list module. It looks like that file just isn't being downloaded properly prior to untar being run. Here's the error message from the conda test, though the others yielded errors this time as well (originally only the conda test failed)

My test for taxonkit/list is here, and it's based on taxonkit/lineage's test So, my questions are: 1. Am I missing some difference between untar in the test for this module vs taxonkit/lineage, or is there something I could add or change to make the test more reliable as is? 2. Alternatively, would it be possible for me to add a "mini" taxdump.tar.gz file to the test-datasets repository that only contains information relevant to the lineages for Homo sapiens and the corresponding subspecies?
