Fog not loading after ubuntu updates

[dejv]

after ubuntu updates fog server is not loading in the browser. Any ideas how to fix it? I am not sure what version I was running however was updated earlier this year

I tried downloading the latest version to /opt/ and running the ./installfog.sh command. the scrip ran and when finished displayed the ip to login however still didnt load

@dejv Can you confirm that apache is running?

ps aux | grep apache

If its not running you might want to inspect the apache error log in /var/logs/apache2 directory.

@george1421 seem that after a couple of hours being left alone it is working again

<snark>Well then, you can almost expect it to stop working without notice some time in the future too. </snark>

With a bit less snark, if it happens again we’ll dig a bit deeper into why. Its strange that it would start again on its own. I can see the OS update messing it up, because it has happened in the past.

@george1421 I guess its better to just stop doing the OS updates.

I am a bit OCD about the updates

Don’t think it’s a good idea. You better learn how to debug an error and fix things instead.

[dejv]

@sebastian-roth you have a point there a good way to learn linux

Hey, issues again, yesterday I updated my ubuntu version from 20.04.6lts to 22.04.2lts however now fog is not loading :S

I checked and apache seems to be running :S any ideas

[Tom Elliott]

@dejv That does not mean apache is running.

Look at the right side and you see the “full command”

You returned the grep command where you were looking for apache.

You could do:
ps -ef | grep -P 'apache|http' | grep -v grep

Or
ps aux | grep -P 'apache|http' | grep -v grep

but from what I can apache definitely isn’t running currently.

@Tom-Elliott seems to be an apache related issue :s tried starting it manually and am getting the below error

root@fog:~# systemctl status apache2.service

I performed the below commands and now

sudo a2dismod php7.4
sudo a2enmod php8.1
systemctl restart apache2

and now on the web I am getting:

Service Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

Apache/2.4.52 (Ubuntu) Server at 192.168.0.58 Port 80

[dejv]

Also when running

sudo apachectl configtest

I was getting :
fog apachectl[941]: AH00558: apache2: Could not reliably determine the server’s fully qualified domain name, using 127.0.1.1. Set the ‘ServerName’ directive globally to suppress this message

So had to add the below command
sudo nano /etc/httpd/conf/httpd.conf
and added : ServerName 127.0.0.1

root@fog:~# sudo apachectl configtest
Syntax OK

Now am getting :

Service Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

@dejv Please try:

systemctl -l status apache2

send out put then also you can do:

systemctl restart apache2
sleep 5
journalctl -xe

And send output here.

I have a server snapshot before the upgrade, I think I will revert back to it and then when it is nearly out of support will backup everything and do a fresh os installation

@dejv Have you attempted to reinstall fog after performing software updates?

Often this can fix things.

Before you just push the butotn, if indeed php is 8.1 you may want to edit the file /opt/fog/.fogsettings

look for instances of php where 7.4 is defined and redefine to php 8.1 as appropriate, then rerun the installer.

Things shoudl fix themselves a bit better.

@dejv changed php version as you instructed, redownloaded latest version, installed and is working ok thanks a lot
