The install script manually installs DotNet 8 but the upgrade script does not update dotnet runtime to v9.0

according to the changelog for v14.0:

Upgraded codebase to use .NET 9 runtime. If you had manually installed the DNS Server or .NET 8 Runtime earlier then you must install .NET 9 Runtime manually before upgrading the DNS server.

  1. Open a shell on the technitium lxc
  2. type update
  3. wait for it to finish updating
  4. restart lxc or sudo systemctl restart dns

❌ Paste the full error output (if available).
