How to upgrade from Ubuntu 14.04 (32-bit) to latest Ubuntu Budgie (64-bit)? [duplicate]

Ubuntu 14.04 (32-bit) is installed on my laptop along with Windows 7. I have barely used Ubuntu, but I'm on it now since Windows is troubling me.

I was looking for a Ubuntu flavour that is light-weight, and I found Ubuntu Budgie, which is also pretty sweet looking, hence I opted for that.

I'd be highly grateful for exact steps on how I can update to the latest version of Ubuntu Budgie (64-bit version.)

Please let me know if I need to update Ubuntu 14.04 as well.

Note: When I was trying to update the OS using Software Updater, I would get the error, "Requires installing from untrusted sources." And I'd have two options, "Settings..." [which leads to the Software Updater] and "Close".

Related Queries:

• Do all the flavours of Ubuntu require the 'original' Ubuntu to be installed, or they are stand-alone operating systems?

• I need an operating system which is light-weight and can run most Windows software. Is Ubuntu Budgie a good pick or should I go for something else?

Device specifications:

• Memory: 3.9 GiB
• Processor: Intel Core i3-2350M @ 2.30GHz x 4
• Graphics: Gallium 0.4 on NVD9
• OS type: 32 bit
• Disk: 47.3 GB

Solution 1:

There's no upgrade possible from 32-bit to 64-bit.

There's no upgrade possible from Ubuntu to Ubuntu-Budgie. It's possible turn standard Ubuntu into something Ubuntu-Budgie look-alike but it's moot for this question.

And even if the original 14.04 was 64-bit thus having a possible upgrade path to Ubuntu 20.04 - 14.04 (EoL) -> 16.04 (about to be EoL) -> 18.04 -> 20.04 - failure is expected and it would take days to complete therefore such process is strongly discouraged.

Conclusion: Backup personal files and install Ubuntu-Budgie 64-bit

Solution 2:

Here's what I did:

• Removed partition for Ubuntu 14.04 (32-bit).

• Removed GRUB bootloader using Easy BCD.

• Installed Lubuntu 20.04 LTS (64-bit) on dual boot.

Its installation time was 7 minutes. It's very lightweight comparatively. It's got some of its other issues, but hey, speed is what matters more. I guess it consumes more power. But my laptop's got 50 minutes on Windows 7. 40 minutes on Lubuntu is a big difference, but not as bad.

Is it possible to "upgrade" from a 32bit to a 64bit installation?
