# Troubleshooting
## `hop: command not found`
Open a new terminal after installation. Confirm the install directory is on
PATH:
```bash
command -v hop
printf '%s\n' "$PATH"
```
The default Unix location is `~/.local/bin`. On Windows it is
`%LOCALAPPDATA%\Programs\Hop`.
## An agent integration does not activate Hop
```bash
hop skill install --force
```
The command refreshes both default skill bundles. Restart the agent client. For
Codex Desktop, mention `$hop` in a task as a deterministic activation fallback.
For another compatible runtime, confirm that it reads `~/.agents/skills` or run
`hop skill install --path /path/to/agent/skills --force`.
## The installer cannot find a release
Only published Gitea Releases appear through the public releases API. Drafts
and an instance that is not live will return an error; published prereleases
are supported. Pin an existing tag with `HOP_VERSION`, or use the source build
until the first release is published.
## Git is too old
Hop requires Git 2.40 or newer for structured, explicit-base `merge-tree`
behavior:
```bash
git --version
```
Upgrade Git through the operating system package manager before retrying.
## Exit code 20: merge conflict
The agent should adopt the returned reconciliation prompt and workspace,
resolve both intents, run `hop check`, propose, and land again. Users should not
need to perform ordinary source merges.
## Exit code 22: validation failed
The accepted head did not advance. Inspect the recorded output, fix the attempt
workspace, and rerun the check.
## Exit code 23 or `Root: diverged`
Hop found visible files or index state it will not overwrite. Preserve those
changes. Capture them as a new Hop task or resolve them intentionally, then
retry `hop land`. Do not bypass this with `hop accept` in interactive workflows.
## Internal ref or object warning
```bash
hop doctor
```
If SQLite is healthy and the report specifically identifies derived refs:
```bash
hop doctor --repair
```
Do not repair while a final validation command is running.
## A secret was pasted
Rotate it. Hop redaction reduces durable exposure but cannot prove that every
credential format, attachment, agent log, or external system omitted the value.
