Hi there,

RPI4 local YNH 4.3.6.2 fresh install.

I can’t install the app Custom Webapp. I had installed YNH previously and an update of the “Custom Webapp” app went badly 3 month ago.

Here is some of the logs :

yep

here is the last line :

postfix/sendmail[10089]: fatal: chdir /var/spool/postfix: No such file or directory

Posfix and dovecot service was also down.
So I create the missing folder /var/spool/postfix

I restarted both services and tried a new install of custom webapp which works.
So thank you for your advice.

before the end YNH return an :

Erreur: "504"

Action: "POST" /yunohost/api/apps

What I’ve found is when I reboot the server, the postfix folder is missing again and so the two services. I don’t host mail on this server but it could be problematic if I reboot again and YNH want to send me alert.

you normally don’t need to create that directory, it’s certainly a consequence of your failing postfix service.
To repai rit you can look at ljf advices : https://forum.yunohost.org/t/impossible-denvoyer-des-mails-postfix-ko/10294/6?u=ewilly

ok thanks

I tried :

yunohost service regen-conf postfix --force

and also :

apt-get install postfix --reinstall
yunohost tools regen-conf postfix
yunohost tools restart postfix

The services won’t start. Each logs ( journalctl / /var/log/mail.err / /var/log/mail.log ) contains the same line :

/var/spool/postfix: No such file or directory

The only way to run postfix and dovecot is to mkdir /var/spool/postfix

I’ve reverse proxy behind my routeur. All the port are open in YNH exposure diagnostics.

Is this directory mount on a tmpfs ? (cat /etc/mtab | grep /var)
What say the log of postfix service after a reboot ? (via the ynh admin web ui or journalctl -u postfix.service)

found it…

it was a line that I wrote into /etc/fstab on my previous instance.

tmpfs /var/spool tmpfs defaults,noatime,mode=1777 0 0

I deleted it, a reboot, and both services are working.

thanks for your help :slight_smile:
