Perfect server automated server Debian 10-11

Trying to install ispconfig on a complete new server with debian 11, hostname is correctly set to biocrumb.pt

Code:

root@biocrumb:~# cat /etc/hosts
127.0.0.1       localhost
::1             localhost ip6-localhost ip6-loopback
ff02::1         ip6-allnodes
ff02::2         ip6-allrouters

# Auto-generated hostname. Please do not remove this comment.
185.53.128.24 biocrumb.pt biocrumb
root@biocrumb:~#

Code:

root@biocrumb:~# hostname -f
biocrumb.pt
root@biocrumb:~#

And when I try to install through the script I get this error:

Code:

[INFO] Checking hostname.
[ERROR] The host name biocrumb.pt of your server is no fully qualified domain name (xyz.domain.com). Please check it is correctly set. (/lib/os/class.ISPConfigDebianOS.inc.php:590)
[ERROR] Exception occured: ISPConfigOSException -> Host name is no FQDN. (/ispconfig.ai.php:15)

What am I doing wrong?

 

(And I just noticed I post this in wrong section of the forum, so I appologize for that)

Scratch everything on the OP, I created a subdomain like it was asked, now I have another issue, install is not succeed.
I used the command (no-quota because it also was giving me an error, but since I don't need it is ok, but FTP I need)

Code:

 wget -O - https://get.ispconfig.org | sh -s -- --no-quota --debug 

after installing a bunch of packages when it gets to install pure-ftpd I get this error and the installation of ISPconfig stops there (I reintalled debian just in case after the first time I got the quota error, so once again completely new server):

Code:

[INFO] Installing packages pure-ftpd-common, pure-ftpd-mysql, awstats, goaccess, awffull
[ERROR] Exception occured: ISPConfigOSException -> Installing packages failed. (/ispconfig.ai.php:15)
root@web:~#

EDIT: found the solution install update-inetd before runing the script fixes the issues for pure-ftpd

 

It's an image from a VPS provider running in OpenVZ so I didn't had much saying about what images could I use.
