Error while installing mailinabox


I am running into below error while installing mail-in-a-box:

Please help. Thanks

Try updating & upgrading your Linux server before to call the MiaB setup:

  1. Update It with:
    apt-get update && apt-get upgrade -y

  2. Upgrade It with:
    apt-get dist-upgrade -y

  3. Clean OLD linux packages with:
    apt-get autoremove -y

  4. reboot

  5. Try installing MiaB again.

Thanks @just4t, it worked. However, it didn’t stop for Let’s Encrypt SSL to take my input and directly started server. In short, it installed without SSL certificate. How can I fix it?

@just4t, please forget about SSL. I see that it can be fixed from admin panel in browser too. Thanks for your help.
