Hi @thotdoc,
Thanks for trying those steps. Based on your account diagnostics, we can see that your SonicTransporter is running a very old Linux kernel (Fedora 25 core), and Roon 2.65 introduced new system requirements: glibc 2.27 or later on Linux. Your unit appears to pre-date that threshold, which is most likely why RoonServer stopped working during the update.
This isn’t something that can be resolved from the Roon side - the underlying OS on the SonicTransporter needs to be updated to meet the new requirements. We’d recommend reaching out to Small Green Computer (the makers of SonicTransporter) directly and asking them to update your unit’s OS to a version that meets the 2.65+ requirements.
You can find more details about the system requirements change in the Roon 2.65 release notes.
