<p>I have experienced the same issue yesterday and after trying the <code>--use-ftp</code> argument without luck (this is proposed as an alternative in the forums), I have downloaded the database from <a href="https://benlangmead.github.io/aws-indexes/k2" rel="nofollow noreferrer">Kraken 2, KrakenUniq and Bracken indexes</a> (<a href="https://github.com/DerrickWood/kraken2/issues/753#issuecomment-1692288857" rel="nofollow noreferrer">ref</a>).</p>

<p>I am attempting to build just the standard Kraken2 Database by using the following command:</p>
<pre><code>kraken2-build --standard --threads 24 --db $DBNAME
</code></pre>
<p>I am returned the following error a few minutes building it:</p>
<pre><code>rsync_from_ncbi.pl: unexpected FTP path (new server?) for 
https://ftp.ncbi.nlm.nih.gov/genomes/all/GCF/000/762/265/GCF_000762265.1_ASM76226v1
</code></pre>
<p>Anyone know why this is happening?</p>

I am attempting to build just the standard Kraken2 Database by using the following command:
kraken2-build --standard --threads 24 --db $DBNAME

I am returned the following error a few minutes building it:
rsync_from_ncbi.pl: unexpected FTP path (new server?) for

Anyone know why this is happening?

I have experienced the same issue yesterday and after trying the `--use-ftp` argument without luck (this is proposed as an alternative in the forums), I have downloaded the database from [Kraken 2, KrakenUniq and Bracken indexes](https://benlangmead.github.io/aws-indexes/k2) ([ref](https://github.com/DerrickWood/kraken2/issues/753#issuecomment-1692288857)).
