我把 Linux 的时区设成 Asia/Tokyo，又手动设置了系统时间，但 tmux 右侧状态栏仍慢一个小时。例如，系统显示 14:37 JST，tmux 却显示 13:37 CST。问题不在 timedatectl set-time：一个早已启动的 tmux server 仍按旧时区格式化状态栏。

sudo timedatectl set-timezone Asia/Tokyo
sudo timedatectl set-ntp false
# aligned to real Asia/Shanghai time
timedatectl set-time "2026-09-26 15:33:00"

OpenAI shipped an official ChatGPT Desktop for Linux in August 2026 (preview), supporting Ubuntu 24.04/26.04, Debian 13, Fedora 43/44 and Arch. Mint 20.3 (focal, glibc 2.31) is nowhere on that list, so I expected a rerun of the Claude Desktop surgery.

It wasn’t. The glibc floor was fine all along — the package is blocked by three library renames and one optional TPM module. The fix is smaller, and the audit is worth showing because the conclusion is the opposite of last time.

Anthropic’s official Claude Desktop .deb declares libc6 (>= 2.34), which means Ubuntu 22.04+ / Mint 21+. On Mint 20.3 (focal, glibc 2.31) apt refuses to install it. It turns out that dependency is an overstatement, and the app runs fine on glibc 2.31 once you know which three files actually need 2.34.
