    How to update base OS (Ubuntu 10.04 LTS packages)?

    gauravphoenix Lurker

      I am successfully able to create VMs based upon Ubuntu 10.04 LTS Server.

      How do I go about updating the base OS packages before the application package gets installed.

       

      My intent is to ship fully updated VM.

       

      I've tried using the Application Pre Install Script and entering :

      apt-get update -q -y >/tmp/test1

      apt-get upgrade -q -y >/tmp/test1

       

      but when I log into transiet VM, I don't see anything creatred in /tmp.

       

      I am okay with using update CIMOM but don't really know if it is a good idea to manually update manifest file.

       

      Thanks,

          My suggestions are;

           

          1. You need to set HTTP_PROXY and FTP_PROXY before installing new web based package.

          2. Instead of /tmp try /root folder for log redirection. Because most of the time /tmp gets cleanup automatically after reboot.

          3. Use apt-get update -q -y 2>&1 /tmp/test1 option (2>&1). So that you can catch the error also.

          4. If possible download the updated ISO from internet and use it in VMware Studio. You need to update its md5sum in build profile.

            Hi, I've just tried your line with an Ubuntu server 10.04.

            At first it didn't work, but I decided to copy the line on the post-script and add an upgrade below.


            That has worked for me

             

            the script looks something like this:

             

            #Update Ubuntu 10.04 before deployment

            apt-get update -q -y 2>&1 /tmp/update.log

            apt-get upgrade -q -y 2>&1 /tmp/upgrade.log

             

            Thanks!

             

            ***********************************************************

             

            Ok, I have to correct my statement on my last post. It has not worked.

            Does anybody know how to update ubuntu server before it gets packed into an OVA file?


            Thanks

              No, don't do this. The entire philosophy of an appliance is that the author (you) controls what is in the appliance, and has validated that it will work. If you use an external service to update packages (especially if you do something as dramatic as try to upgrade the OS!) you have no idea if your application will work at all. How do you support such a hybrid when a customer calls to ask for help? You have no idea the state of the appliance, so you will have no idea how to fix something when it breaks. You don't have to use the VAMI update feature, but you should use something that depends on *you* putting software into the appliance, as opposed to an external third party that you do not control, and that software has been tested with your application.

               

              Get the updated packages from Ubuntu, put them into another application repository called, say, "OS_updates", and *test* the new Ubuntu packages with your application software. Then, and only then, should you make the update repository (with the new Ubuntu packages) available to your customers' appliances.

                Hi asharpe,

                thank you very much for your answer. I guess I did not explain what I was trying to do before I posted my answer.

                 

                What I want to do is create an appliance with the most up to date packages of Ubuntu server 10.04 (for security reasons). I'm not using ubuntu 12.04 LTS because it has issues with Tomcat at this point in time, and I'm not using 11.10 because it's not a TLS version of the OS.

                 

                So the idea as you've pointed out, is not to update the appliance when the user deploys it, or have an update button. But to have VMware Studio update the packages when creating the VM's files so that I can freeze it there and have a safer version of what I want to deploy. Otherwise it would be impossible to determine if clients problems were caused by the OS or the program.

                 

                The other option would be to create an ISO image of the OS with the latest software, or even a parallel repository and use that. But I'm not quite sure how to do that.

                 

                Any ideas on how to achieve what I'm trying to do?

                Thanks

                  What you can do is create your appliance with Studio, list all the packages and versions (dpkg -l), update it with Ubuntu's mechanism, see which packages were updated, and then copy those packages from the apt cache into a separate repository in Studio.

                    Interesting, I'll give that a try.

                    Thanks

                      Ok, I've done what you suggested with "apt-get -d upgrade" and put all the files Studio.

                      Now the OVA is 150MB bigger. Any way I can lower that down? it's meant to be updates, not new debs...

                       

                      Thanks

                        Well, updates to debs can very well be larger, and new deb packages can certainly be added, if a package that you have had new dependencies added (likely), then the VM can certainly be larger. I'm afraid you'll have to ask Ubuntu why things are bigger.

                          Hi asharpe, thanks for that. Late night, wasn't thinking properly... makes a lot of sence!

                           

                          I have detected a problem though with the installation of the downloaded deb files.

                          All of a suden I have realized that neither my application or MySQL is in the resulting VM. I've had a look at the postinstall.log and found that it actually installs the deb files and at the very end, for some reason that I cannot explain, it removes them:

                          Download run_cut_files.sh

                          Note, selecting mysql-client-5.1 instead of mysql-client
                          The following packages were automatically installed and are no longer required:
                            libnet-daemon-perl liblcms1 libdbi-perl libdbd-mysql-perl libplrpc-perl
                          Use 'apt-get autoremove' to remove them.
                          The following packages will be REMOVED:
                            certmanager mysql-client-5.1 mysql-server mysql-server-5.1

                           

                          When I remove the repository that contains the updates I get a working VM with my program "certmanager" and MySQL and everything (except updates).

                          This is my postinstall script:

                           

                          #!/bin/bash
                          # Un-comment the following lines for reducing the space occupied for the

                          # template is located at /opt/vmware/etc/footprint and should be used with

                          wget_opt="-nH --cut-dirs=2 -nv"
                          echo Download run_cut_files.sh
                          wget $wget_opt -P /tmp $cut_files_url 2>$wget_err 1>/dev/null
                          if [ $? -ne 0 ]; then
                             errmsg=`cat $wget_err`
                             echo Abort: $errmsg
                          else
                             echo Execute run_cut_files.sh

                          fi

                          Any ideas? Is there any other file I could have a look at?

                            It looks like your removal of the mysql client also decided to remove the server, or the cut_files script is being over-ambitious. You will probably have to comment out lines until your application and mysql stick around, and then you'll know who's doing it.
