Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

Hello Alejandro, the error message from the package installation script is:

---

The hostname -f command returned: amora-diarioas

Your system needs to have a fully qualified domain name (fqdn) in
order to install the var-qmail packages.

Installation aborted

---

You can probably fix this via the hostnamectl program.

Thanks
