setup_db.pl not finding the SILVA database

[MatteoSchiavinato]

Hi, I'm having trouble installing the database with setup_db.pl. This is likely connected with Issue #41 but I don't think it's the same, because the script I cloned from github today (May 25th, 2021) likely has fixed that issue already.

I see that the script has a hard-coded link to the current SILVA version, but this is the log I get:

Is there a workaround?

I solved it using 1) the workaround suggested in Issue #41 , and 2) installing File::Fetch which wasn't already installed in my case. Please add File::Fetch to the required dependencies!
