Hello bridge operators,

During yesterday's upgrade of our WebTunnel docker image, some bridges
stopped working due to an operating system issue[1]. Only WebTunnel
operators using our official Docker image are affected.

If your bridge is affected and you don’t apply this fix, it will remain
non-functional and users will not be able to connect. You need to take
action now! 

### How to check if your bridge is affected

Run the command:

`docker ps` 

If your WebTunnel container is stuck in a restart loop (shows
`Restarting (1)` or similar message), then your bridge needs fixing:

```
thetorproject/webtunnel-bridge:latest   "/usr/local/bin/star…"   22 hours ago   
Restarting (1) 21 seconds ago              webtunnelBridge5a35b7dd47c6   
containrrr/
```

### How to fix your WebTunnel docker bridge

1. List your Docker volumes:

```
docker volume list 
```

2. Identify the persistent volume for Tor, then run (adjust the volume name 
accordingly):

```
docker run --rm -it -v root_webtunnel-tor-state:/var/lib/tor debian chown -R 
100 /var/lib/tor
```

3. Restart your bridge:

```
docker compose up -d
```

If you need help, please reach out to us on irc #tor-relays

Thank you for running bridges!
