Upgrade Script

[Wirezfree]

Hi Jerry & Misko,

Updated...

Tested on my HP Laptop i5-4200u not i5-4500u
Including re-boot the upgrade took approx 7 mins, the home-upgrade part seemed to be almost instantaneous.

All appears to be working fine, tested networking, printing and common apps.

Many Thanks... Dave

Hello Jerry and misko,

the upgrade went smoothly, it took 19 minutes to complete, including checking for updates after completion.
All is working correctly with zero errors after upgrade.

Brilliant, thank you for responding bitsnpcs

Thanks for letting us know Dave. The home-upgrade part should be very quick, it backs up a few kilobytes worth of files, then modifies existing ones. Lots of code but small outcome

Hi Jerry,

I plan on testing this process sometime this month.  I was not looking forward to a full clean LL 2.2 install given all the customization I have make, but always wanted the increased speed and latest packages.

I took a look at the script and would like to suggest some code changes for easier maintenance and reduced overhead.  Feel free to ignore, and I must mention this code is not fully tested (I tested bits of changes to ensure the resulting commands are equivalent).

Thank you riser, could you please edit your code to include #comments for any changes/additions.

[riser]

I essentially made 3 changes:
- Consolidate running zenity based commands using a function (so any changes to behavior are done in one place and code is cleaner)
- Replaced the multiple 'sed -i' replacements of the theme text with a single 'sed -f'
- Moved/changed logic to exit if user does not want to upgrade

further to my post about the upgrade taking 45 mins,
I should have added that this was on a old netbook with a 16 gig SSD, which slow read write times made it almost unusable.
But LL made it at least usable and this 45 mins should be the maximum time anyone should take.

I think Dave's 7 minutes is pretty awesome.

Keith.

Hello!

I ran the upgrade script on a Samsung RV515-A03US with 8GB RAM and a 1TB HD, and it only took a couple of minutes to upgrade. This is a LOT less time than ANY of the Ubuntu upgrades take. Will keep you informed as I upgrade the other lappies around here.

I ended up with some leftover GRUB entries from 2.0, which I edited out with Grub Customizer. Other than that, it worked like a champ...

UPDATE: I upgraded the 32-bit 2.0 install on my Gateway Tablet PC (M285E, 2 GB RAM, 320GB HD) to 2.2. It was successful, but I had to run boot-repair on it to fix GRUB, then reinstalled grub-customizer. All better now, and what you came up with is certainly better than not being able to upgrade!

Did the upgrade on the HP nc6320 (4 GB RAM, 1 TB HD) after (temporarily) removing grub-customizer, and reinstalled GC afterward. No issues other than having to update the GRUB entries to reflect 2.2 instead of 2.0...

Thanks Rob. I haven't decided yet the simplest way to deploy the upgrade process. We'll come up with something
