    Default Linux: clearing out gumf

    I'm trying to create a LiveUSB version of my current install of Ubuntu 16.04, mainly so that I can transfer it onto a new machine.

    I've achieved this before (over a year ago now !) using Systemback, which makes the process very easy. Systemback isnt in development any more so help is difficult to find. *

    The main issue I'm having at the moment is that the single file created is about 7Gb. Which is far too big to be converted to an ISO file.

    So, I need to shrink the overall size of the "distro" which is proving awkward, there's not a huge amount in it anyway.

    Current installation is:
    Ubuntu 16.04 lts (up to date with all updates)
    Chrome
    GIMP
    Sublime
    LibreofficeWriter
    LibreOfficeCalc
    LAMP

    and a few small utilities like Xpad, GColor2, Pulseaudio,BlueMan, UnityTweakTool.

    That's less packages than the original install!

    Most of the results in google for "shrink" involve systems or method to reduce the size of an existing ISO file, rather than reducing the overall install first

    So, any suggestions for shrinking the size of the "distro" before I generate the ISO?









    * geek-rant: wtf do half decent packages like Systemback seem to have such short lives? Its almost like the rest of the linux-geek society kill them off if they make life under Linux nice and easy. Bah!

    Why?

    Why not just install Linux on the new machine and install anything extra you need that doesn't come with the distro? That's what I do.

    That's the obvious answer yes, but i have certain things setup nicely that i dint want to go through the hassle of setting up anew. (ssh keys to remote servers is just one simpler example)

    With that out of the way: doesn't Linux store stuff like that in your home folder? I have /home on its own partition, if I needed to install it on a new machine I'd set it up the same way and copy the old /home to the new /home.

    RB - why not just copy the setup files back once you’ve installed from fresh? Much smaller?

    I also want to set up a 'LiveUSB', that is - an entire OS on a USB stick that is either runnable "as is", or installable from the USB.

    As said - I've done this before, but previously the ISO was below 4Gb, so it worked fine. The ISO files I'm currently generating are over that and so don't work - hence wanting to reduce the size of the current installation BEFORE creating the ISO file to install on the USB.

    What tool did you use to make the 7gb single file?
    Pinguy builder - pinguyos - should compress and build an ISO for you of your current system as is. This will run and install from a usb stick
    You can take the hard disk out of the old machine and plug it in to the new one, test to see if it runs ok. If you want to use a new hdd then minitool partition wizard will copy the old disc to the new one.
    Cleaning - var/cache/apt/archives - all the zip files in there can be removed.
    Web browser[s] caches [Not cookies if you use auto logins.]
    home/.cache/thumbnails/ - the subfolders can be emptied.

    Might try that next time.

    Couldn't find the browser caches (but a good idea).
    The others seem to have done the trick - thanks for the useful suggestions.
