I have attempted to upgrade to v73 today and get an error I am not sure about.

When I try **curl -s [https://mailinabox.email/setup.sh](https://mailinabox.email/setup.sh) | sudo bash** I get:

ubuntu@box:~$ curl -s [https://mailinabox.email/setup.sh](https://mailinabox.email/setup.sh) | sudo bash

When I try **sudo mailinabox** I get the expected grey on blue messages and then this:

Your Mail-in-a-Box is running.

Please log in to the control panel for further instructions at:

[https://box.xxxxxxx.com/admin](https://box.xxxxxxx.com/admin)

If you have a DNS problem put the box’s IP address in the URL  
([https://5x.6x.1xx.2xx/admin](https://5x.6x.1xx.2xx/admin)) but then check the TLS fingerprint:  
xx:xx:xx:xx:xx:xx:xx:xx  
ubuntu@box:~$

I am a bit lost on this… after a reboot, status page still says new version is available

This message says that something in your installation folder has changed. If you are not aware of any changes, you can just move the folder away. `mv mailinabox mailinabox_backup` and rerun the upgrade / installation command (the one starting with curl).  
If all is well after this you can remove the mailimabox\_backup folder.  
If you’re curious about what’s changed you can do

```auto
cd mailinabox
git diff

```

Thank you for that. I did the mv and re-ran the curl/bash command but still it errors with:

ubuntu@box:~$ curl -s [https://mailinabox.email/setup.sh](https://mailinabox.email/setup.sh) | sudo bash

Clearly, I had fiddled with dns\_update.py to reduce TTL, however i restored the backup file i took, but still update script fails with error above.

Am I facing a backup and restore action to clean build with v73?

Also, the correct install command (from the instructions) is:

`curl -s https://mailinabox.email/setup.sh | sudo -E bash`

Note the **`-E`** option.

And if you’ve been changing things, some kind of **`git restore`** might clean it up.

This is an error message coming from Git.  
It’s saying that you have local changes in the file `management/dns_update.py`. Did you ever edit that file?

Run the following command:

```bash
(cd ~/mailinabox ; git diff)

```

This will show you all local changes in the `mailinabox` directory. In theory there shouldn’t be any, but clearly there are.

To reset the `mailinabox` directory to the original, run this command:

```bash
(cd ~/mailinabox ; git reset --hard HEAD)

```

Then run the `setup.sh` script as before.
