It seems like you’re listing different Linux distributions and versions, but the formatting is a bit unclear. Here’s a breakdown of the versions you mentioned and some context:
-
Alibaba Cloud Linux 3.21.04
- This is a Linux distribution optimized for Alibaba Cloud, based on RHEL/CentOS. Version 3.21.04 likely refers to a specific release (possibly kernel version or OS build).
- Alibaba Cloud Linux is designed for cloud environments and maintains compatibility with CentOS/RHEL.
-
CentOS 8.2
- CentOS 8.2 was a minor release of CentOS 8 (now discontinued). CentOS 8 reached End-of-Life (EOL) on December 31, 2021, and was replaced by CentOS Stream.
- Users migrating from CentOS 8 often switch to alternatives like Rocky Linux, AlmaLinux, or Oracle Linux.
-
Ubuntu 20.04 (assuming you meant 20.04)
- Ubuntu 20.04 LTS (Focal Fossa) is a Long-Term Support release supported until April 2025. It’s widely used for servers and desktops.
- If you meant another version (e.g., 20.10), note that non-LTS Ubuntu releases have shorter support lifecycles.
Clarifications Needed:
- Is there a specific question about these distributions (e.g., compatibility, migration, or usage)?
- For Alibaba Cloud Linux 3.21.04, you may want to check Alibaba’s official docs for exact details, as version numbering can vary.
- CentOS 8.2 is no longer supported—consider migrating to a RHEL-compatible alternative.
