Adds a concise post-update validation checklist (git status, hermes doctor, version check, gateway status). Adapted from PR #3050 with corrections — removed inaccurate submodule claim (hermes update already handles submodules) and tightened the checklist. Cherry-picked and adapted from PR #3050.

# Updating & Uninstalling
|
||
|
||
## Updating
|
||
|
||
Update to the latest version with a single command:
|
||
|
||
```bash
|
||
hermes update
|
||
```
|
||
|
||
This pulls the latest code, updates dependencies, and prompts you to configure any new options that were added since your last update.
|
||
|
||
:::tip
|
||
`hermes update` automatically detects new configuration options and prompts you to add them. If you skipped that prompt, you can manually run `hermes config check` to see missing options, then `hermes config migrate` to interactively add them.
|
||
:::
|
||
|
||
### What happens during an update
|
||
|
||
When you run `hermes update`, the following steps occur:
|
||
|
||
1. **Git pull** — pulls the latest code from the `main` branch and updates submodules
|
||
2. **Dependency install** — runs `uv pip install -e ".[all]"` to pick up new or changed dependencies
|
||
3. **Config migration** — detects new config options added since your version and prompts you to set them
|
||
4. **Gateway auto-restart** — if the gateway service is running (systemd on Linux, launchd on macOS), it is **automatically restarted** after the update completes so the new code takes effect immediately
|
||
|
||
Expected output looks like:
|
||
|
||
```
|
||
$ hermes update
|
||
Updating Hermes Agent...
|
||
📥 Pulling latest code...
|
||
Already up to date. (or: Updating abc1234..def5678)
|
||
📦 Updating dependencies...
|
||
✅ Dependencies updated
|
||
🔍 Checking for new config options...
|
||
✅ Config is up to date (or: Found 2 new options — running migration...)
|
||
🔄 Restarting gateway service...
|
||
✅ Gateway restarted
|
||
✅ Hermes Agent updated successfully!
|
||
```
|
||
|
||
### Recommended Post-Update Validation
|
||
|
||
`hermes update` handles the main update path, but a quick validation confirms everything landed cleanly:
|
||
|
||
1. `git status --short` — if the tree is unexpectedly dirty, inspect before continuing
|
||
2. `hermes doctor` — checks config, dependencies, and service health
|
||
3. `hermes --version` — confirm the version bumped as expected
|
||
4. If you use the gateway: `hermes gateway status`
|
||
5. If `doctor` reports npm audit issues: run `npm audit fix` in the flagged directory
|
||
|
||
:::warning Dirty working tree after update
|
||
If `git status --short` shows unexpected changes after `hermes update`, stop and inspect them before continuing. This usually means local modifications were reapplied on top of the updated code, or a dependency step refreshed lockfiles.
|
||
:::
|
||
|
||
### Checking your current version
|
||
|
||
```bash
|
||
hermes version
|
||
```
|
||
|
||
Compare against the latest release at the [GitHub releases page](https://github.com/NousResearch/hermes-agent/releases) or check for available updates:
|
||
|
||
```bash
|
||
hermes update --check
|
||
```
|
||
|
||
### Updating from Messaging Platforms
|
||
|
||
You can also update directly from Telegram, Discord, Slack, or WhatsApp by sending:
|
||
|
||
```
|
||
/update
|
||
```
|
||
|
||
This pulls the latest code, updates dependencies, and restarts the gateway. The bot will briefly go offline during the restart (typically 5–15 seconds) and then resume.
|
||
|
||
### Manual Update
|
||
|
||
If you installed manually (not via the quick installer):
|
||
|
||
```bash
|
||
cd /path/to/hermes-agent
|
||
export VIRTUAL_ENV="$(pwd)/venv"
|
||
|
||
# Pull latest code and submodules
|
||
git pull origin main
|
||
git submodule update --init --recursive
|
||
|
||
# Reinstall (picks up new dependencies)
|
||
uv pip install -e ".[all]"
|
||
uv pip install -e "./tinker-atropos"
|
||
|
||
# Check for new config options
|
||
hermes config check
|
||
hermes config migrate # Interactively add any missing options
|
||
```
|
||
|
||
### Rollback instructions
|
||
|
||
If an update introduces a problem, you can roll back to a previous version:
|
||
|
||
```bash
|
||
cd /path/to/hermes-agent
|
||
|
||
# List recent versions
|
||
git log --oneline -10
|
||
|
||
# Roll back to a specific commit
|
||
git checkout <commit-hash>
|
||
git submodule update --init --recursive
|
||
uv pip install -e ".[all]"
|
||
|
||
# Restart the gateway if running
|
||
hermes gateway restart
|
||
```
|
||
|
||
To roll back to a specific release tag:
|
||
|
||
```bash
|
||
git checkout v0.6.0
|
||
git submodule update --init --recursive
|
||
uv pip install -e ".[all]"
|
||
```
|
||
|
||
:::warning
|
||
Rolling back may cause config incompatibilities if new options were added. Run `hermes config check` after rolling back and remove any unrecognized options from `config.yaml` if you encounter errors.
|
||
:::
|
||
|
||
### Note for Nix users
|
||
|
||
If you installed via Nix flake, updates are managed through the Nix package manager:
|
||
|
||
```bash
|
||
# Update the flake input
|
||
nix flake update hermes-agent
|
||
|
||
# Or rebuild with the latest
|
||
nix profile upgrade hermes-agent
|
||
```
|
||
|
||
Nix installations are immutable — rollback is handled by Nix's generation system:
|
||
|
||
```bash
|
||
nix profile rollback
|
||
```
|
||
|
||
See [Nix Setup](./nix-setup.md) for more details.
|
||

|
||
|
||
## Uninstalling
|
||
|
||
```bash
|
||
hermes uninstall
|
||
```
|
||
|
||
The uninstaller gives you the option to keep your configuration files (`~/.hermes/`) for a future reinstall.
|
||
|
||
### Manual Uninstall
|
||
|
||
```bash
|
||
rm -f ~/.local/bin/hermes
|
||
rm -rf /path/to/hermes-agent
|
||
rm -rf ~/.hermes # Optional — keep if you plan to reinstall
|
||
```
|
||
|
||
:::info
|
||
If you installed the gateway as a system service, stop and disable it first:
|
||
```bash
|
||
hermes gateway stop
|
||
# Linux: systemctl --user disable hermes-gateway
|
||
# macOS: launchctl remove ai.hermes.gateway
|
||
```
