Updating DeepSeek TUI only feels confusing when you forget which install path owns the tool

The right update route depends on the package path that installed the binary in the first place. Most upgrade confusion comes from mixing install methods or forgetting which one is active in your shell.

Why upgrades get messy

Upgrade problems often come from duplicate installs, stale PATH entries, or switching ecosystems halfway through setup.

What to check before upgrading

Which package manager installed the active `deepseek` command?
Do you have older copies from a previous npm, cargo, or binary install?
Will your shell still point to the newest version after the update finishes?
