TurnKey Linux Virtual Appliance Library

how do I get tklbam to work with custom packages and APT repositories?

tklbam seems not to work ??

today i have been testing tklbam ... I did follow the instructions in the case study:

1 - launch a turnkey appliance from amazon console (turnkey apache tomcat lucid)

2 - run tklbam init ; tklbam backup

2 - install some packages ... nxserver, lxde, chrome and sun java.

3 - run tklbam backup

4 - And now ... I start another instance of the same appliance  

5 - run tklbam init ; tklbam backup ; tklbam restore {id of the backup of the other appliance}

6- restart

The backup does not show any error but the instance seems no to work, in particular , I tried 

the command java -version , and i got the message "java command not found"

I do not know if I am doing something wrong. Please could any one bring some light ?


Thank you and kind regards.

Need more information

Could you share the backup and restore logs? Also it might be helpful to understand how exactly you installed additional packages. Was it all done through the package management system? Did you add any custom repositories?

I have found that the nx

I have found that the nx server has not been backup, maybe due to the way i installed it :



dpkg -i nxclient_3.4.0-7_i386.deb
dpkg -i nxnode_3.4.0-14_i386.deb
dpkg -i nxserver_3.4.0-14_i386.deb
Please can anyone confirm that this type of manual installation wont be backup, so we can take care of them in another way ?

From my understanding...

AFAIK TKLBAM leverages the package management system to install any extra packages from default appliance state (ie any extra packages that aren't installed originally).

I'm not sure but I suspect that as this package isn't available from a repo, TKLBAM doesn't know where to get it from and hence its not included. It's a scenerio which probably should be accounted for.

If that's the case, you may be able to work around it by manually including the app path as part of the backup. Another possible workaround may be to host a repo locally for that deb (and any other custom ones).

Configure repositories before restoring

Try and configure the package repositories before performing the restore. If you want this to be done automatically, look into setting up a custom hook that runs on restore in the "pre" state. If packages are only available as downloadable *.deb files and are not installable through an APT repository (e.g., NX) I recommend you save the packages in /root/debs and install them from the custom hook in the "post" state.

$ cat /etc/tklbam/hooks.d/example

#!/bin/bash -e
# This is a disabled hook example.
# To enable, make it executable: chmod +x /etc/tklbam/hooks.d/example

# hooks are always called with two arguments

if [ "$op" = "restore" ]; then
    echo -n "A restore operation called this hook "
elif [ "$op" = "backup" ]; then
    echo -n "A backup operation called this hook "

if [ "$state" = "pre" ]; then
    echo "right BEFORE duplicity was invoked"
elif [ "$state" = "post" ]; then
    echo "AFTER the $op operation finished"

# `false` returns a non-zero exitcode
# Uncomment the next line to raise an error


As JedMeister correctly suspected, when you tklbam-restore from a new installation, TKLBAM is not aware of the new package repositories on your old installation and it doesn't attempt to synchronize them. This is by design, as otherwise we wouldn't be able to use TKLBAM to upgrade between different versions of Ubuntu or migrate between Ubuntu and the upcoming Debian versions, etc.

TKLBAM hook example

One of my cloud servers uses packages from multiverse, which is not enabled by default in TKL, which means even though TKLBAM knows about them in the backup, they are not installed when I launch a new server from the backup.

I wanted everything to be automated, so I created the following TKLBAM hook, and thought that others might find it useful:

#!/bin/bash -e
# hooks are always called with two arguments
op=$1       # backup / restore
state=$2    # pre / post

if [ "$op" == "restore" ] && [ "$state" == "post" ]; then
    sed -i "/multiverse/ s/# //g" /etc/apt/sources.list.d/*.list
    export DEBIAN_FRONTEND=noninteractive
    apt-get update
    apt-get -y install PACKAGE1 PACKAGE2

Note that just enabling multiverse in state=pre and letting TKLBAM take care of the package installation won't work on a newly launched server because the backed up filesystem is not restored until after package installation.
