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) root@AMD64:/etc/apt# apt-get install synaptic-trinity Reading package lists... Done Building dependency tree Reading state information... Done The following NEW packages will be installed: synaptic-trinity 0 upgraded, 1 newly installed, 0 to remove and 1 not upgraded.
