MetaPhlAn version 4.0.4 (17 Jan 2023)

metaphlan --install

After 20%, download process stopped. I tried using screen command, and after two days nothing.

Also, I’ve tried using wget directly from the repository without success.

Thanks

Hi @diecasfranco  
Do you have enough space in your machine for the download? Does the download stop suddenly at 20% or is the download so slow that for reaching 20% it takes days?

Hi @diecasfranco  
Then, I am not sure what is really happening during your download. It does not seem a timeout problem from the cmprod1 server since your download has not been killed. I can only suggest you to try again maybe using a different network

Hi, I had the same issue, I believe it might be due to the server’s firewall rules.

I had to run this from a different network to finish downloading:

```sh
wget --continue --limit-rate=20M http://cmprod1.cibio.unitn.it/biobakery4/metaphlan_databases/bowtie2_indexes/mpa_vOct22_CHOCOPhlAnSGB_202212_bt2.tar

```

I think `--limit-rate=20M` did the trick (but didn’t work on the same network as I guess I was already blacklisted or something). It caps the download speed at 20MB/s.

Hope that helps.

Hi @simone.pignotti  
That was the solution, using wget.

Thank you!
