sagemath on Manjaro (or Debian)

df -h will NOT show if a card is fake,, f3 or htestw(for win) write a sector/cluster every GB,
read it back to check. A fake "wraps"after real size is full. The test will take some hours, run overnight
I would not suggest for your 256GB SD

A bit dated as a main OS, based on stretch, 64bit kernel and 32bit userland, put on 16 or 32GB card
balena internally does something like [zcat|xzcat] <image>|dd of=somewhere, don't need to expand image
Nor do you with dd, pipelines work well
I am inclined to think the problem is manjaro's uboot, a work around is from login screen (sddm?),
drop down menu in upper right, pwr button icon ->reboot
If you have an UPDATED mrfixit SD, changing uboot on emmc is easy
save emmc mbr, write 1st 16M SD ->emmc, restore emmc mbr

Ok, I will try f3, which seems to be available on Fedora 32. If I need to do it outside my micro sd drive, Manjaro Kde is still available so I can search for f3 there? Otherwise, I will need to buy a 32GB card and try on my 256GB card?

I have been struggling for a week to setup everything to make me concentrate back on work. It seems more difficult than I thought. I am about to choose between Debian Bullseye with Gnome or Fedora Workstation 32. Debian Bullseye is giving me extra problems such as sound card, unusual "poff" noises, and Bullseye is refusing to connect my 2TB drive with "exfat" errors. I had a 1TB hard disk and Bullseye recognized and mounted it without a problem, puzzling.

Both Debian and Ubuntu families disappointed me for now. Luckily, Fedora 32 seems working. I burned it on the Micro SD card and everything from keyboard to soundcard is working as intended. When I was installing Sagemath, it gave me a not enough space error. I realized Fedora uses only the image size of the img and does not touch the rest of the 256gb. I resized it easily with Gnome Disks to 256gb and now it is working nicely.

However, the boot problem is persisting with fedora as well. There is also a small annoyance with plymouth splash of fedora not working but this seems to be the best I can get.

I will keep you updated if I make any progre
