Regarding the OS Upgrade of the Linux Servers of the Zengaku Computer System (Updated 25/10/9)

(Added 2025/10/9)
As scheduled, during scheduled maintenance on Sunday, September 28th, we upgraded the Ubuntu OS on the Zengaku Computer System’s Linux servers (icho01, icho02, and kiri) from 22.04 LTS to 24.04 LTS.
Most operations will function as before. However, this time we changed the configuration to mount home directories automatically.

During scheduled maintenance on Sunday, September 28th, the Ubuntu OS on the Zengaku Computer System’s Linux servers (icho01, icho02, and kiri) will be upgraded from 22.04 LTS to 24.04 LTS. These servers were originally scheduled to be upgraded in February, but due to operational issues, the upgrade was canceled. We have since confirmed the procedure for a successful upgrade.

Partial suspension of the upgrade of the Ubuntu (Linux) servers of the Zengaku Computer System

Ubuntu (Linux) on the Zengaku Computer System was scheduled to be upgraded from 20.04 LTS to 24.04 LTS.
Linux on terminals was upgraded to 24.04 as planned, but Linux on servers (icho01, icho02, kiri) was upgraded to 22.04 because the system became unstable when upgraded to 24.04 LTS.
