No Webinterface after Upgrade to 3.X - 502 Bad Gateway (I cleared my browser cache)

BaalsRevenge · 22. Januar 2018

I have recently updated my OMV installation to version 3.16.0-5-amd64. After update I can still log in via SSH, can access my ftp-shares, yet the web-interface gives the message "502 Bad Gateway" and in the next line "Nginx". I have already cleared my browser cache and tested this from various devices, the result is always the same. The output of service nginx status is as follows:

● nginx.service - A high performance web server and a reverse proxy server

From a different thread I have seen that there might be an issue with omv service itself, and service openmediavault status gives the following:

● openmediavault.service - LSB: Basic initialization of the OpenMediaVault system

I have also seen a hint to include the line "OMV_DATAMODELS_DIR="/usr/share/openmediavault/datamodels" in /etc/defaults/openmediavault, this was already there. Does someone have an idea what to try next?

Many thanks

Seems like I am running into the same problems.

Were you able to resolve your problem?

ryecoaaron · 12. Februar 2018

Usually having an incompatible OMV 2.x plugin installed on OMV 3.x is the problem here.

berritorre · 12. Februar 2018

Hy Ryecoaaron,

I thought I had uninstalled all plugins before upgrading. At least via the GUI there was no Plugin left. How do I find out if there is still a plugin installed and how do I uninstall it via SSH?

I am currently investigating and it seems nginx isn't starting.

ryecoaaron · 12. Februar 2018

dpkg -l | grep openm will list the plugins. apt-get remove PLUGIN_NAME will remove a plugin

berritorre · 12. Februar 2018

Hmm, doesn't seem that there are plugins running at all:

Bash

root@pdb-matrix:~# dpkg -l | grep openm
iF  openmediavault                 3.0.96                             all          Open network attached storage solution
ii  openmediavault-keyring         1.0                                all          GnuPG archive keys of the OpenMediaVault archive

Only if Openmediavault or openmediavault-keyring are plugins.

berritorre · 12. Februar 2018

But when checking on nginx I get this:

Code

root@pdb-matrix:~# service nginx status

So I searched a bit and some suggeted that this might be cause by Apache running in the background.

so I did this:

Code

root@pdb-matrix:~# sudo apachectl stop
AH00548: NameVirtualHost has no effect and will be removed in the next release /etc/apache2/ports.conf:1
httpd (no pid file) not running

ryecoaaron · 12. Februar 2018

openmediavault package itself didn't finish installing. apt-get -f install should help. The apache packages should be purged to eliminate conflicts - apt-get purge apache2*

berritorre · 12. Februar 2018

Thanks Ryecoaaron.

Did the apt-get -f install and got this:

Code

dpkg: error processing package openmediavault (--configure):

Hi! Was out of the office for some time, but I am now back to try to get this solved.

So somehow I am running into trouble with the webinterface. I can synchronize data to the shares on my server, I can access them, but I can't get into the webinterface, as it gives me a 502 error by nginx.

I tried to run your recommendations again and here are the errors I get:

When I run apt-get upgrade it looks pretty much the same. But will give that in the next message because the response is too long.

So if I read those error messages correctly, openmediavault and php7.0-fpm haven't been installed correctly?

berritorre · 26. August 2021

OK, so almost 3,5 years later and I am still stuck here. As the file server worked, I just left it be, but without the Web GUI I can't change anything, I can't really add new users, nothing. So before I totally kill this installation and set up a new one (either with OMV or any other software to provide a file server), I will try another time to get this error fixed (and hopefully update to a newer version of OMV, which is of course preferred over doing a new install and having to transfer almost 3GB of data back and forth.

So I managed to check via command line that I am currently on 4.1.13-1.

My suspicion was that some plugin caused problems during the update, but I don't know.

But then above I see errors regarding php7.0-fpm, and "ERROR: [pool openmediavault-webgui] cannot get u…webgui'", so I guess the problem might be with php7.0-fpm?

Any help would be appreciated!
