SVN version 4547 blank page on Create New Image link

Tom Elliott

I’m still siding with the idea that it’s LDAP plugin related, almost directly.

I say this because under the same revision and even after, I’m not seeing any issues. Only difference is I haven’t tried using the LDAP Plugin.

Thanks Tom, that makes sense. I can’t remove the plugin so was looking to do a clean reinstall of FOG to wipe out and start again. I’ve run this to clear settings

mv /opt/fog/.fogsettings /opt/fog/fogsettings-firstInstall

then removed all FOG related files

#Uninstall FOG

#remove service
sudo rm -rf /etc/init.d/FOGImageReplicator
sudo rm -rf /etc/init.d/FOGMulticastManager
sudo rm -rf /etc/init.d/FOGScheduler

#delete fog database
sudo mysql
#(or 'sudo mysql -u root -p' if you set a root password for mysql)
drop database fog;
quit

#Remove files
sudo rm -rf /var/www/fog 
sudo rm -rf /opt/fog 
sudo rm -rf /tftpboot 
sudo rm -rf /images 

#delete fog system user
sudo userdel fog

Tried installing latest SVN version but getting repeated error:

Sorry, answer not recognized

I can see that this is coming from the last few lines of the installfog.sh file

        ;;
        [nN]*)
        echo "  FOG installer exited by user request."
        exit 1;
        ;;
        *)
        echo "";
        echo "  Sorry, answer not recognized."
        echo "";
        ;;
    esac
done

but cannot see why. I’ve read on other posts that this can happen when copy/pasting and the installer reading a carriage return or similar but I’m typing commands by hand.

regards, Kiweegie.

How are you running the installer?

My guess is you’re copying pasting from another tutorial? For example, if you’re running the command as:

./installfog.sh

(That line has a purposeful New line but displays as a regular single line command) this could pose the issue.

One of the easiest ways to disable plugins is obviously to use the plugin page on the GUI, but if you can’t get to the page obviously that won’t work. The next way is to use either phpmyadmin or other remote GUI SQL tool to modify the database fog on the table plugins. Look for your selected plugin and disable it by setting the pState and pInstalled values to 0.

The other way, and my preferred when possible, is to run it directly out of MySQL.

mysql -u root [-p'PASSIFSET'] fog (Only run the -p if you have a mysql password set.)

Then the command:

UPDATE plugins SET pInstalled=0,pState=0 WHERE pName='LDAP';

This should essentially turn off the plugin and no longer require it’s hooks to be active.

Hi Tom, appreciate the quick reply.

Steps I’ve followed to get and install latest svn version are:

sudo mkdir /opt/svn
cd /opt/svn
sudo svn checkout https://svn.code.sf.net/p/freeghost/code/trunk
cd trunk/bin
sudo ./installfog.sh

This line in your reply doesn’t compute my side though, could you elaborate please?

(That line has a purposeful New line but displays as a regular single line command) this could pose the issue.

Am I somehow running the installer incorrectly? This has worked just fine in the past up to and including yesterday morning.

Happy to use MysQL commands provided to disable plugins - I can access the GUI but there is no delete option there to remove them. However I need to get FOG reinstalled first…

regards, Kiweegie.

@Kiweegie The ./installfog.sh line I gave, I forced it to have a new line in my prior message. I was just warning you not to use it from the forums.

Kiweegie

OK, I appear to be missing something here. I ended up wiping my existing FOG Server VM and rebuilding from scratch.

On a clean install of Centos 6.5 and the latest SVN download I’m still getting the repeated error below when launching /opt/svn/trunk/bin/installfog.sh

Sorry, answer not recognized

Am I missing somethign obvious? The README.md file within the downloaded SVN trunk folder suggests the method I’ve used is correct.

regards Kiweegie.

@Kiweegie Does this file exist? What’s in it? /opt/fog/.fogsettings

cat /opt/fog/.fogsettings
ls -la /opt/fog

Kiweegie

@Wayne-Workman Hi Wayne thanks for getting back to me,

No, the directory /opt/fog does not exist. But given this is a brand new OS install now and I haven’t been able to install FOG yet due to the error below, I wouldn’t expect to see it yet.

Sorry, answer not recognized

Something I’ve been meaning to ask elsewhere but may help in this case, how does one pull down a specific version of the trunk via SVN version, is that possible? Wondering if i specify an earlier SVN version it could rule out issue with this particular installer?

Just a thought…

regards Kiweegie.

Wayne Workman

@Kiweegie https://wiki.fogproject.org/wiki/index.php/Upgrade_to_Revision

so for example -

cd ~
cd svn/trunk
svn co -r 2922 https://svn.code.sf.net/p/freeghost/code/trunk

DO NOT use 2922 !!! It is SOOO OLD! This is just an example!!!

Kiweegie

@Wayne-Workman Thanks Wayne. A possibly (and feel free to omit the possibly) stupid question. How does one find a list of valid SVN release version numbers? I’m sure when I had this working before on the FOG icon on the web GUI it shows the revision number.

This is from another of our FOG servers which is running ok.

Imgur link

Yet when I try and download that version on my faulty FOG server I get this

[root@fogserver svn]# svn co -r 4457 https://svn.code.sf.net/p/freeghost/code/trunk trunk/
svn: No such revision 4457

If on the working server I go to Fog Configuration it shows the following version info

Version: 4457

You are not running the most current version of FOG!

You are currently running version: 4457

Latest stable version is 1.2.0

Latest svn version is 3959

Latest git version is 4557

So I tried downloading the 3959 version via SVN and no dice - same error as before “Sorry, answer not recognised”.

Do the GIT and SVN versions get updated separately? I’m trying git now based on this wiki link:

regards Kiweegie.

Kiweegie

@Wayne-Workman well that was quick, but not successful.

using latest git version same error is occuring - “Sorry, answer not recognised”

I have followed the steps on installing on Centos from the wiki so selinux and iptables etc are disabled and all repos are added on.

What could be triggering that last stanza in the installfog.sh file?

cheers Kiweegie

Tom Elliott

Remoted in and found there was an error in the reading of the linux release name.

Tom Elliott

This is now fixed. Apparently that bugs been there for a while.

Kiweegie

@Tom-Elliott Thanks again for the help Tom, greatly appreciated. Please mark this call as resolved.

regards, Kiweegie

darkxeno

Im have this same issue on 4571 what did you have to do to fix this?

Tom Elliott

@darkxeno What is the same problem? Exactly? What? “It don’t work” isn’t good enough, sorry.

darkxeno

I get a blank page when i hit create a new image

Tom Elliott

Somewhere, apparently, threads got crossed. I thought this thread was in reference to the installfog issue, where it kept reporting “Sorry, answer not recognized” but apparently this is not the case.

darkxeno

Oh ok I was able to get it back by copying the image the image management page.php file form the old verison I had before It was in the 3000s build and was able to get the page to load but now when i go to edit a image i get a basic page with no formatting lol
