I get this error while installing yunohost on VDS server.
I have just started to install yunohost and I cannot solve some problems because I do not have much knowledge. Can you help me?

Hi ugukkiraz,

Which ‘it’ is it that you want to install? I see an apt-get command, but I think that is not the command that you executed yourself directly. Is it part of a Yunohost app?

Edit to add:

I see you have been struggling with this problem before. Would you mind running and posting the output of

$ cat /etc/postfix/main.cf|grep myhostname

smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
myhostname = 185.255.4.90
mydestination = $myhostname, /etc/mailname, 185.255.4.90, localhost.255.4.90, localhost

Ah! That is the problem. It should be a name, not a number.

What is the output of

$ hostname -f

I changed the host name and it worked, thanks.

Now I’m getting this error while installing :

When I install this command alone, this screen appears, what should I do?

Great!

The error says

Please check /var/log/yunohost-installation_20250122_104006.log for debugging

Was there any hint in that file?

It may be that the previous installation attempt already wrote your IP address as hostname into some of the configuration files.
One that comes to mind is main.cf, because of the previous

newaliases: fatal: file /etc/postfix/main.cf: parameter myhostname: bad parameter value: 185.255…

You could check that one by

$ cat /etc/postfix/main.cf | grep myhostname

and verifying the output.

That would mean retrying installation, check errors, manually correct configuration, retry installation, and so on.

Alternative: you know how to find and correct the hostname now. I think the easiest way is now to redeploy Debian on your VPS and restart the installation.

Depending on your host, it should take seconds to minutes to redeploy Debian, and depending on the specs of the VPS, the same goes for installation of Yunohost. It would be way less frustrating than troubleshooting the system even before you get started.

apt is a bit of a pain because typically it doesn’t really explain what’s the issue when there’s a dependency problem …

We can try to force to spit out the actual issue by adding some package that seem problematic in the command line. Let’s try something like :

apt-get install --assume-yes -o Dpkg::Options::=--force-confold -o APT::install-recommends=true yunohost yunohost-admin postfix postfix-ldap dovecot-core opendkim acl yunohost-portal  libdbd-ldap-perl j2cli haveged postsrsd

Uh wokay then it feels like the debian repo disappeared from your install … or maybe just need a apt update (but that should have been done by the install script)

What does apt update display ?

Be sure you are on debian 12

Debian versiyon 12.9 VPS

What local language is it set? Could it be Turkish?

14

Turkish :slight_smile:

15

@Aleks could it be the same issue as discussed before in the forum or github (I don’t remember)?

16

Try reinstalling debian with English language and retry the yunohost install
Afterwards you can change the language

I tried in English and it still gives the same error.

I edited them like this and it installed but now I get this error. There is no app to list here, either because no web app yet is installed on the server, or because you don’t have access to any. Please check with the admins of the server for more infos!
