[solved] Communication Failure - No PlugIns listed

Solo0815 · 28. September 2013

I can't view the plugins, because everytime i click on "() Check", i get a "An error has occurred"-Message. Details shows only "Communication Error". Does anybody know, what it is?

omv-engined is running

davidh2k · 28. September 2013

If I remember correctly this is a bug where the engined is not running correctly. I think just rebooting solved my problem the last time.

Greetings
David

Solo0815 · 29. September 2013

doesn't help unfortunately. Any other solutions?
Can I get a debug-output of omv-engined somehow?

Edit: It has to do something with /etc/apt/sources.list.d/openmediavault-local.list
If I move the file to another location, all is working. Moving it back brings up the error.

I cleared /var/cache/openmediavault/archives and uploaded only one plugin to make a new "Packages"-file. Same error :shock: :?

Same problem here, right after installing:
linux-base
linux-image-2.6.32-5-486
linux-libc-dev
I updated via OMV web administration.

ryecoaaron · 29. September 2013

You can run engined in debug mode by:

monit stop omv-engined
omv-engined -df

Solo0815 · 29. September 2013

Here's the debug-log:
http://pastebin.com/raw.php?i=yMtfbYKz

the last error repeats continuing in the debug-output

It shows it is sending all of the plugins back. Not sure why it would give you a communication error unless one of the package description is malformed?? But it doesn't show any errors.

Solo0815 · 29. September 2013

Is this worth a bug-report? If yes, I'll write one

ryecoaaron · 29. September 2013

Not yet. What is the output of:

dpkg -l | grep suhosin

Not sure how/why the suhosin patch seems is installed on your system. This hardens php but may not allow certain things to happen in omv.

Solo0815 · 29. September 2013

Code

root@hoppetz ----- {So Sep 29, 19:44:58} -------------------------  
~$ dpkg -l | grep suhosin
root@hoppetz ----- {So Sep 29, 19:45:01} -------------------------  
~$ echo $?
1

The output is nothing and the package is not installed. Where do you see, it is installed?

ryecoaaron · 29. September 2013

In your error log:

Apache/2.2.16 (Debian) mod_fcgid/2.3.6 PHP/5.3.3-7+squeeze17 with Suhosin-Patch mod_ssl/2.2.16 OpenSSL/0.9.8o

Here is mine:

Apache/2.2.16 (Debian) DAV/2 mod_fcgid/2.3.6 mod_ssl/2.2.16 OpenSSL/0.9.8o

I don't know why it is installed if the php5-suhosin package isn't installed.

Solo0815 · 29. September 2013

Edit: I'll try something ...

ryecoaaron · 29. September 2013

Here are mine. The one that makes me wonder is apache2-mod-php5. I also noticed you adodb installed??

Solo0815 · 29. September 2013

I think the package came from http://debian.oppserver.net/xbmc/ which I enabled when I tried to get XBMC-server working. The package could also be installed while I tried to get a WebFilemanager working.
I removed the repo from /etc/apt/sources.list and did

Code

service apache2 stop
apt-get remove libapache2-mod-*
apt-get install --reinstall openmediavault

It worked, until I uploaded and installed the 3rd-party-plugin-deb via WebGUI.
Now, whats wrong?

ryecoaaron · 29. September 2013

The other repo might have install php5 with the suhosin patch. I would reinstall php5

apt-get install --reinstall php5-cgi php5-cli php5-common

Solo0815 · 29. September 2013

While I tried to remove some apache2-packages i got following error:

Code

E: Sub-process returned an error code

ryecoaaron · 29. September 2013

It looks like it is trying to remove apache2. You shouldn't have to reinstall any apache packages. Just php unless that didn't work. Does the helper-functions file exist?

Solo0815 · 30. September 2013

I tried to remove and reinstall all apache2-packages.
After removing and reinstalling them, it works until I add the "omv-extrasorg"-package and click Check after install.
This is reproducable for me, If I remove the omvextras-package the Check-button works. :shock: :shock: :shock:
btw: it is the newest package v. 0.5.5

My packages now:
