The remaining problem is that the installer expects the new Microsoft Root CAs to be available while most linux distros only ship the old one. After installing "Microsoft Root Certificate Authority 2010" and "Microsoft Root Certificate Authority 2011" as trusted root certificates, the installation finishes successfully for me.
Are you saying the official .NET 4.6.2 offline setup works once the 2011 root CA's are installed?
