Then I rolled back the server on the previous date Snapshot and then I am getting a error message on the contabo side. Attached the error message. I also need the person to verify the storage is a SSD or NVMe? If you know to customise the server for the best performance then I would need this as well.

Your quote should be on the lower end of a "Simple Project", that is closer to US$30 than US$250. cPanel has found three issues that prevent a (LATER) upgrade from CENTOS 7.9 to Almalinux 8. Your task is to fix these three issues: 1. You are using MySQL 5.7 community server. This version is not available for AlmaLinux 8. You first need to update your MySQL server to 8.0 or later. You can update to version 8.0 using the following command: /usr/local/cpanel/bin/whmapi1 start_background_mysql_upgrade version=8.0 Once the MySQL upgrade is finished, you can then retry to elevate to AlmaLinux 8. 2. One or more enabled YUM repo are currently unsupported. You should disable these repositories and remove packa...
