Please note that I performed a package update, and now I'm getting error messages. So far I have tried to clean up old kernel images, but it hasn't helped (see https://askubuntu.com/questions/872012/problems-upgrading-kernel-in-ubuntu-14-04). Also, I have checked https://groups.google.com/forum/#!searchin/bigbluebutton-dev/dpkg$3A$20error$20processing$20package$20linux-image-generic|sort:relevance/bigbluebutton-dev/mc6MUVD7Y-4/GK6F11XGX5oJ

Here are the steps I executed:

sudo -i
dpkg --configure -a
apt-get update
apt-get -f install
OLDCONF=$(dpkg -l|grep “^rc”|awk ‘{print $2}’)
CURKERNEL=$(uname -r|sed ‘s/-*[a-z]//g’|sed ‘s/-386//g’)
LINUXPKG=”linux-(image|headers|ubuntu-modules|restricted-modules)”
METALINUXPKG=”linux-(image|headers|restricted-modules)-(generic|i386|server|common|rt|xen)”
OLDKERNELS=$(dpkg -l|awk ‘{print $2}’|grep -E $LINUXPKG |grep -vE $METALINUXPKG|grep -v $CURKERNEL)
apt-get clean
apt-get purge $OLDCONF
apt-get purge $OLDKERNELS
apt-get autoremove
apt-get dist-upgrade
apt-get clean

Here are the original error messages I was getting.

dpkg: error processing package linux-image-generic (--configure):

dpkg: dependency problems prevent configuration of linux-generic:

Also, when I try to run demo12.jsp, this is the error I'm getting. Does anyone have any suggestions? TIA.

An Error has occured:

Hi Roger,

Taking a guess ... if your trying to upgrade from 1.0 to 1.1, we would not recommend upgrading Ubuntu 14.04 to Ubuntu

See http://docs.bigbluebutton.org/install/install.html which states

If you want to upgrade a BigBlueButton 1.0 (or earlier) server, we recommend to starting with a separate clean Ubuntu 16.04 64-bit server, install BigBlueButton 1.1 on it, and then transfer over existing recordings.

Regards,... Fred

Hi Fred,

Thank you! Please note that I am running Ubuntu 16--it was a fresh install, and everything was working fine until I tried to perform this ubuntu apt-get install update and apt-get install dist-upgrade.

rmoore@Annapurna:~$ lsb_release -a

No LSB modules are available.

Distributor ID: Ubuntu

Description: Ubuntu 16.04.3 LTS

Release: 16.04

Codename: xenial

This is what I see when I check the version of BBB:

rmoore@Annapurna:~/dev/bigbluebutton$ sudo bbb-conf

BigBlueButton Configuration Utility - Version 1.1.0

Hi Roger,

Where did you get this script? If you want to remove old kernels, the `apt-get autoremove` will safely do it.

We're not sure how to solve the error messages you are seeing

> linux-generic depends on linux-image-generic (= 4.4.0.89.95); however:

They are not related to BigBlueButton. Recommend you Google the above error messages and see if there are other resources that can help.

For BigBlueButton, try

sudo bbb-conf --setip <IP/hostname>

and see if that gets you running. If not, post the output of

dpkg -l | grep bbb

sudo bbb-conf --check

and we'll see if there are clues as to why BigBlueButton isn't loading.

Regards,... Fred

Please note that I removed and re-installed BBB using this and I also used setip afterwards:

$ sudo apt-get purge --auto-remove bigbluebutton

$ sudo apt-get install bigbluebutton

FYI, I got the script from here: https://askubuntu.com/questions/872012/problems-upgrading-kernel-in-ubuntu-14-04

So now BBB loads, but I'm still getting that null pointer exception when I try to load http://tuberedu.ca/demo/demo12.jsp

OK, somehow these files got deleted so I re-added them and it works now:

./bigbluebutton-client/client/conf/config.xml

./bigbluebutton-client/src/conf/config.xml
