I have never used those tools, I usually just dd the iso to a usb. I am assuming you are on a linux distribution already. I would download a fresh iso and verify the checksum.
Then use dd to write to the usb. I use this format, and of course replace the path to iso bit and /dev/sdx (your usb)with what is relevant to your situation.
Just open terminal and type
I still use one. I like having a small device for just that purpose. It doesn't have a touch screen, which is how I prefer it. I despise touchscreens. I like to interact with my phone as little as possible, especially while driving.
Stardew Valley is $15 USD. It's pretty laid back. Easy to set down and pick back up. I like to play it when my head is all over the place and want something soothing.
You want bleeding edge but are moving to Ubuntu 20.04, which was released in 2019 with a 2025 EOL? No DE from that release's repo will be bleeding edge. You can manually install the newest releases of software you want, but that's not really a "just works" solution either. You'll run into dependency hell at some point. I'm not really sure what you're going for. But as far as a stable DE goes, and if that is the main concern as implied in the title, XFCE has been pretty darn solid for me.
Open /usr/share/dbus-1/services/org.xfce.xfce4-notityd.Notifications.service in a text editor, like nano, vim, etc. For instance, in terminal type
nano /usr/share/dbus-1/services/org.xfce.xfce4-notityd.Notifications.service
This will open the file org.xfce.xfce4-notityd.Notifications.service
In that file, find the line Name=org.freedesktop.Notifications
Change that line to read Name=org.freedesktop.NotificationsNone
Save the file, in nano it's ctrl+x it will ask if you want to modify file,type y for yes. Next it will ask if you want to keep file the same name, just hit enter. Then reboot your computer.
Arch Wiki has a bunch you can try to dig through https://wiki.archlinux.org/title/Power_management
However if it were me I'd just reinstall the power manager if that was easy for you to manage. You can turn off the xfce-4 notifier at that point since they both won't be able to access the dbus at the same time. Look at /usr/share/dbus-1/services/org.xfce.xfce4-notityd.Notifications.service
Then change Name=org.freedesktop.Notifications to Name=org.freedesktop.NotificationsNone and reboot.
I don't know if you have any where you live, but sometimes you can find local appliance repair shops that might sell parts. Even if they don't have a new element hanging around they may have an old usable one to sell you. I used to work at one and we kept ahold of discontinued parts to use for repairs or sale.
Yay keeps a cache of packages to help building go a bit faster. Sometimes it can cause issues if things have changed that the cached build system can't detect. Clean build removes the cached files and re-downloads everything to install. None means don't clean build, all means all listed packages that need upgrading. don't know about installed vs installed I never used those flags. The numbers correspond to the number by the package if you want to only select specific ones.
You will also want to make sure the filter isn't clogged up. Most overheating is going to be an airflow issue. You can also look up online how to pull it apart and check components. You may also have a loose power connection somewhere. Make sure the vacuum is unplugged before you mess with it.
If you never shave, you probably shouldn't go out doing it the first time. It's a nudist resort, not a porn shoot. Probably be a mix of both. Course I suppose it depends on the specific place. But I've never met a nudist, that I know of any way, that bothered to shave.
