Ever since Canonical is pushing for a Flutter based installer since 23.04 (With legacy installer still Included) and 24.04 (Which a legacy installer is no longer included), I like a flutter, I loved it, it’s an installation process on some devices (Mostly a handhelds) has errors and cannot get Ubuntu to work properly (USB ports on certain handhelds has limited power and Flutter based installer probably did not include something like on a legacy installer such as an A-Sync).
As one person said in this topic cannot boot to Ubuntu after installing it. For this one, I couldn’t install Ubuntu 24.04 or later.
It looks like this during a process of the installation while I’ve waited and waited.
Do not know if that would solve problem, but have had Ubuntu not install on older low spec laptop system, possibly similar to a low spec hand held. Just would not install. Where Kubuntu would install.
Issue was not installer per se, but that system did not have new enough specs to support full Ubuntu which assumes newer system.
Have you tried a lighter weight flavor? https://ubuntu.com/download/flavours
Light weight flavors:
Lubuntu, Xubuntu, Ubuntu MATE, Budgie
Flavors of Ubuntu only come with three years of supported life (five years applies to Ubuntu Desktop, Ubuntu Server but not flavors)
I did found the reason why I can’t install Ubuntu 24.04.1 LTS on my GPD WIN Mini (2024), so the built-in USB slot has a limited watts speed which the installer may not support that, so the only solution that I did is to use USB 3.0 Hub with its DC-5V AC-Power cord adapter that came with for my flash drive with Ubuntu 24.04.1 LTS installer to connect it, yes it’s able to install Ubuntu 24.04.1 LTS on my GPD WIN Mini (2024) just fine. Probably it needs a little bit extra amount of watts for Ubuntu 24.04.1 LTS to be installed and using USB 3.0 Hub with DC-5V power cord adapter will boost up volts and watts for a bit.
Do you folks have any further questions about that trick?
If so, felt free to ask.
More like whatever hardware you have plugged-in to the USB slot requires more power than it provides, and that has nothing to do with the OS. Glad you found a solution though!
Under my FYI, I ain’t saying the Operating System itself is the reason, but I could say the flutter-based installer (Due to based on snap) may run a little bit slower, which will cost more watts (Watt hours) for the hardware support.
Sure, some people usually complains about snap due to slower speed by the way. Now I can use Ubuntu for my business again, especially making games, so they’ll use deb apps because the loading speed is much faster, but I use snap for my business.
Sure, it would require more Watt Hours, but not total watts. Watt Hours would be a measurement over time, whereas the total watts are how much energy it requires in the moment.
That’s over-simplified, but that might help you understand.
Translating your reply to get better English for some people “Typos detected”.
Great point @eeickmeyer, I appreciate about the difference between Total Watts and Watt hours , I just never study more details about watts very much, but did you know there’s such thing as Performance per watt or simply PPW?
Which I’m not sure if that is a same thing as Watt hours or Total Watts, again I never study about watts very much, but it’s part of the processors and/or graphics processing units. Bigger amount of PPW, the better performance is the processors and/or graphics processing units especially how much GHz or something.
or worse, Ubuntu will not be as popular because of this.
