With Gitea running, and from the directory Gitea's binary is located, execute: `./gitea admin regenerate hooks`
This ensures that application and configuration file paths in repository Git Hooks are consistent and applicable to the current installation. If these paths are not updated, repository `push` actions will fail.
### Using Docker (`restore`)
There is also no support for a recovery command in a Docker-based gitea instance. The restore process contains the same steps as described in the previous section but with different paths.
Example:
```sh
# open bash session in container
docker exec --user git -it 2a83b293548e bash
# unzip your backup file within the container
unzip gitea-dump-1610949662.zip
cd gitea-dump-1610949662
# restore the gitea data
mv data/* /data/gitea
# restore the repositories itself
mv repos/* /data/git/repositories/
# adjust file permissions
chown -R git:git /data
# Regenerate Git Hooks
/usr/local/bin/gitea -c '/data/gitea/conf/app.ini' admin regenerate hooks
```
The default user in the gitea container is `git` (1000:1000). Please replace `2a83b293548e` with your gitea container id or name.
These are the default paths used in the container:
```text
DEFAULT CONFIGURATION:
CustomPath: /data/gitea (GITEA_CUSTOM)
CustomConf: /data/gitea/conf/app.ini
AppPath: /usr/local/bin/gitea
AppWorkPath: /usr/local/bin
```
### Using Docker-rootless (`restore`)
The restore workflow in Docker-rootless containers differs only in the directories to be used:
```sh
# open bash session in container
docker exec --user git -it 2a83b293548e bash
# unzip your backup file within the container
unzip gitea-dump-1610949662.zip
cd gitea-dump-1610949662
# restore the app.ini
mv data/conf/app.ini /etc/gitea/app.ini
# restore the gitea data
mv data/* /var/lib/gitea
# restore the repositories itself
mv repos/* /var/lib/gitea/git/repositories
# adjust file permissions
chown -R git:git /etc/gitea/app.ini /var/lib/gitea
# Regenerate Git Hooks
/usr/local/bin/gitea -c '/etc/gitea/app.ini' admin regenerate hooks
```
