Error when installing Kraken2

[rpaul5]

Dear developer,
When installing Kraken2 with the following command: kraken2-build --standard --threads 24 --db MY_KRAKEN2_DB

I get this error:
unexpected FTP path (new server?) for https://ftp.ncbi.nlm.nih.gov/genomes/all/GCF/000/762/265/GCF_000762265.1_ASM76226v1

How do I solve this issue?

I encountered the same issue and applied the following and it seems to have worked:

I have encountered this exact same issue, but when I went to modify rsync_from_ncbi.pl, I found that line 46 already has ^https://. Changing it to ^ftp:// did not resolve the issue. So what now? The only resolution to this problem I can find here is to change that line to ^https://.

Re-running the build script at different times (to account for NCBI server issues) does not result in any success.

I skipped the build step by downloading and extracting an already-built standard database from here: https://benlangmead.github.io/aws-indexes/k2

Thank you @SergeyBaikal for suggesting this in issue #551.

Seems to be a fine workaround.
