Struggling to get PI OS working on a 3B (lemmy.ca)

Got a couple rpi 3Bs I'd like to use headless.

Downloaded 32bit pi os lite, flashed it to an sd card, powered on and did the initial setup (select keyboard layout, set first user+pass).

As soon as I'm dropped into a shell, I run 'sudo apt update' then 'sudo apt upgrade -y'.

Once these finish, I type 'sudo reboot'; the pi reboots, shows the rainbow splash, about a dozen lines of kernal boot messages then the video output dies and after a couple seconds the act light stops flashing too. Disconnecting power and powering it again does the same thing.

I don't think it's hardware failure as I get the same results with both 3Bs and with a 4B.

I don't know what to do from here.

I've spent the last 6 hours retrying this with both the 32 and 64 bit versions of pi os light. I can't get past the initial update/upgrade.

Anyone got any ideas? Anyone got a spare sd card, a pi 3B, and some free time to see if I'm just stupid somehow? I don't understand what I'm doing wrong.

/edit: RESULTS!

I can only assume this was a bad sd card. Tried a different card, with the exact same procedure: it finally booted after an upgrade.

Ran the update/upgrade again + a dist-upgrade and a couple more reboots. Up and running.

Excuse me while I go grab an image of that working card to file away.

@Darkassassin07 I've had some slightly similar experiences with my 4b. There are a crapload of bad SD cards in the marketplace. The backup tool works well. I try to be in the habit of making a full image onto a demonstrably working spare card every couple weeks.

I try to be in the habit of making a full image onto a demonstrably working spare card every couple weeks.

That's a whole lot of writing to an sd card, wearing it out. It may fail by the time you want to read it. You also destroy each previous backup by creating a new one.

Each of my rpis backup to my main server nightly using dd via ssh. The server then keeps historical backups of those .img files via Borg so I can pull any version from any day of the last year or so.
