I have been trying to install the Buster release for several days.  I installed the tdebase-trinity package about 3 days ago, but the next day when I tried to download individual packages all I get is error messages.

I could not find on the web site, where you should report problems with the mirror so I posted here.  Any suggestions as to where to report this?

This is the error message for the last thing I tried to download. (there were others that didn't work)
