I’m trying to install mail-in-a-box on a OVH VPS using a custom DNS server. I’ve tried installed twice with a clean OS and am still receiving the same errors.

At the end of an install I receive this in the console, whether that’s normal or not I’m unsure.

Ignoring the above, I then try to add another user but then get slapped with another 500 error.

On top of that, when I want to create a SSL certificate. The CSR code doesn’t show up to allow me to create a certificate. Someone help? D:

Something went very wrong.

Can you see if there’s anything helpful in `/var/log/syslog` when you try to access that part of the control panel?

I don’t think the log is showing anything helpful however I’m not great at understanding this very well. I’ve linked the log however it just shows a bunch of [UFW BLOCK]

Here’s the relevant part:

This was actually reported once before but not solved: [https://github.com/mail-in-a-box/mailinabox/issues/277](https://github.com/mail-in-a-box/mailinabox/issues/277)

Could you run:

```
openssl x509 -req -days 365 -in /tmp/tmpg1dhv0m7 -signkey /home/user-data/ssl/ssl_private_key.pem -out /home/user-data/ssl/panther.io/ssl_certificate.pem

```

on the command line and paste the output here?

Oh uh yeah that makes sense since it was a temporary file and is gone now.

I wonder if OVH provides a /tmp directory that behaves a little different from normal. I’m spinning up an OVH server now to test a possible solution.

Alright great! Thanks for your help! - Your free to use mine considering I have no use for it atm and the long wait times for OVH to create and install your VPS.

Oh that’d be easier. Can you add my ssh public key to your box and let me know its IP?

What’s the name of the user account? (If it’s `root`, `user`, or `ubuntu`, I tried that but got a password prompt, which would mean the key probably isn’t added correctly.)

Might not have, just use the password login. [rest deleted by JoshData—got it thanks]

Thanks.

My earlier diagnosis wasn’t right. OVH is providing you with an Ubuntu image that is missing `/dev/stdin`, `/dev/stdout`, `/dev/stderr`. I have never seen that before and I think OVH is wrong. But I’ve committed a fix anyway:

> <https://github.com/mail-in-a-box/mailinabox/commit/4f98d470a0f60273a34326d22c517a89f0bc1b08>

I’ve updated your system to the latest development version of Mail-in-a-Box so you have that fix. It all _should_ work now, but let me know. Thanks for working through this with me.

No problem! Glad you could assist me with this.
