Problems with downloading the standard database

[SergeyBaikal]

1. I see that the problem has not been solved with downloading the databases, partly because of the NСBI.
   I have a problem even when specifying --use-ftp. I'm from Russia and after downloading about 1.5 GB, the connection is broken. And the download speed is very, very slow. I tried to download both from my home computer and from my work.
   kraken2-build --standard --threads 4 --use-ftp --db /media/sf_Shared_Folder/
   After several attempts, I get an empty command prompt after typing this command and nothing happens.

2. Through rsync change FTP to HTTPS

3. Use only the home directory, otherwise there will be permission issues.

4. Who has a proxy at work, write this in the bashrc file: export RSYNC_PROXY="proxy:port"
   proxy and port your organization, for example 127.0.0.1:3128

5. I saw an amazing thing. Download progress is not shown, even the file does not appear in the folder. It appears after download.
   The database -standard already occupies more than 170 GB!

6. If you have problems downloading the plasmid database, then change the script.
   Use HTTPS instead for plasmids, update path #529 (comment)

7. In order not to start installing all the databases, install those that could not be installed.
   kraken2-build --download-library plasmid --db kraken-Sdb
   kraken2-build --build --db kraken-Sdb --threads 32

It turns out that there is already an assembled database ...
