    upgrading from CD - DELETES your recordings!

    There is supposed to be a way to upgrade Mythbuntu to the next version by downloading the installer CD ISO file, burning a CD and having the update come from the CD, rather than over the Internet. This is to prevent an over-the-Internet upgrade which literally takes multiple hours.

    My goal was to go from 11.04 to 11.10 to 12.04.

    I followed this:
    http://www.liberiangeek.net/2012/04/...ubuntu-cd-dvd/

    They instruct you to boot the pc with the CD, click Install Mythbuntu, and then choose Upgrade from XX to XX.

    I backed up my boot partition with clonezilla so I could go back to a working 11.04 if the upgrade went bad.
    I didn't back up the recordings partition (/var/lib/mythtv) because it is huge, and it isn't supposed to get touched during an upgrade, anyway.

    I put the CD in the drive and booted up to the installer screens.
    All seemed to proceed OK and the upgrade even kept my desktop wallpaper and a few folder icons I put on the desktop.

    When I got done, I found that ALL my recordings were gone!!
    The "/var/lib/mythtv/pretty" folder I put in my last install is gone.

    It looks like the installer wiped out the /var/lib/mythtv partition and rebuilt it!

    WHAT KIND OF UPGRADE IS THAT?

    Isn't the idea of upgrading to only change the operating system files and keep your recordings, etc.???

    Did you use a 12.04 or 12.04.1 ISO? Or did you use a 11.10 ISO first to go from 11.04 to 11.10 to 12.04?

    I used the 11.10 32-bit ISO as my first upgrade step.
    It's my understanding that you must upgrade 1 version at a time, with no version skips.

    I read the info from the link you posted.

    When using the live cd to upgrade, it wipes /var/lib/mythtv/* (presumably /var/*) meaning you lose the database and the default storage group locations
    It sounds EXACTLY what happened on my system - the /var/lib/mythtv partion was wiped - mysql database, and all recorded video files.

    I downloaded the 11.10 ISO file (last night) February 03, 2013, 7:54:28 PM Central Standard Time.

    So, this time bomb is still out in the download folders.

    That 11.10 ISO needs to be DELETED IMMEDIATELY!

    I've thought this for the last 4 or 5 years.

    If a dangerously buggy ISO (such as 11.10) is released, it needs to be deleted from public download sites after it is discovered. Then, after the bugs are fixed, a NEW ISO will be created and released.

    Case in point: this 11.10 release has poison in it that will delete important files during an upgrade! The poison was reported in March of 2012 - about 6 months after the October release. I'm suggesting that the poison ISOs should have been deleted in March 2012 so no more people would have their their working systems destroyed.

    It makes sense to me that a policy like this become a matter of course in the Ubuntu/Mythbuntu community, to prevent needless damage to systems.
