To run current versions of VS Code (including the VS Code Server used for Remote-SSH), your system must meet these minimums:

• GLIBC Version: 2.28 or higher.
• Supported OS Examples: Ubuntu 20.04+, Debian 10+, and RHEL 8+. [1, 2]

Options for Older Kernels

If your system uses an older kernel that cannot be upgraded, you have three main workarounds:

• Downgrade to Version 1.85: This is the last version that supports older glibc environments. You can download it from the VS Code Updates page. After installing, you should disable automatic updates in settings (update.mode: none).
• Use VS Code for the Web: You can access a browser-based version of the editor at vscode.dev, which does not have the same local system library requirements.
• Remote Development Legacy Support: For some remote scenarios, Microsoft introduced a temporary "legacy server" migration path in version 1.97 to help bridge the gap for connecting to older Linux servers. [1, 2, 3, 4, 5]

Troubleshooting Connectivity

If you are using Remote-SSH and seeing "Missing GLIBC" errors:

1. Check your remote system's glibc version by running ldd --version in the terminal.
2. If it is below 2.28, you must either upgrade the remote OS or use the VS Code 1.85 client to connect.
3. Some users have had success using custom toolchains (like crosstool-NG) to build a compatible sysroot on older systems, though this is a complex, unofficial manual fix. [1, 2, 3, 4, 5]
