Hi I am finding it quite difficult to update my discourse through PuTTY. When I run the command

```
cd /var/discourse
git pull
./launcher rebuild app

```

I get the following message

> You have less than 5GB of free space on the disk where /var/lib/docker is located. You will need more space to continue  
> Filesystem Size Used Avail Use% Mounted on  
> /dev/disk/by-label/DOROOT 30G 24G 4.2G 86% /  
> Would you like to attempt to recover space by cleaning docker images and containers in the system?(y/N)

When I hit Y, it simply keep showing this message and nothing happens:

> Total reclaimed space: 0B  
> If the cleanup was successful, you may try again now

Please help on how to solve it. When I check my discourse backup, its just less than 500MB and I wonder how come I have used up all the space?

Discourse needs much more disk space than the size of the backup, in fact it’s the complete Discourse docker image that runs a database server, redis and much more plus all the uncompressed data.

You can check the real occupied space on your system via  
`df -h`

Although it might be already performed by recovering space during rebuild, you can try this

```
apt-get autoclean
apt-get autoremove
cd /var/discourse
./launcher cleanup

```
