 ====== Scheduled Maintenance ====== ====== Scheduled Maintenance ======
  
-This page is being updated. 
- 
-===== Upgrade of machines 2017 ===== 
- 
-Machines to upgrade: **30** 
- 
-==== Reasons: ====  
-  * Main reason is to avoid security holes and update libraries. 
-  * Libraries not present in the distribution will be provided with a new mechanism implemented with success by Lunarc. It will be in a test state during 2017. 
-  * OpenSuse 13.1 is out of support since November 2016; the software is already old. 
- 
-==== Target distribution ==== 
- 
-  * Ubuntu 16.04 will be supported until 2021 and is my preference. There will be no more machine update until that time. 
-  * OpenSuSE Leap can be installed upon request. Its release cycle and support is unclear, therefore I am not supporting it anymore. 
- 
-==== Tentative Schedule ==== 
- 
-==== Status of other machines ====
