When attempting to install AlmaLinux 10 on a SuperMicro dedicated server, the installation may fail with the following error messages:
systemd[1]: Failed to fork off sandboxing environment for executing generators: Protocol error
systemd[1]: Freezing execution.
Failed to start up manager.
The installer will not proceed beyond this point.
This issue can occur when the AlmaLinux 10 ISO is mounted from a remote server with high network latency. During the boot and initialization process, systemd is unable to reliably communicate with the ISO over a slow or unstable connection, which leads to the failure above.
To resolve the issue, ensure that the ISO is mounted from a low-latency source. You can do this in two ways:
Preferred: Mount the ISO from a server located in the same data center as the target SuperMicro server.
Alternative: Use a physical medium (such as a USB stick) to provide the installation ISO directly to the server.
Both methods eliminate the latency that causes systemd to fail during startup.
