Huh, I haven't upgraded my Raspberry Pi running Pi-Hole DNS blocking in a while...

Err:1 raspbian.raspberrypi.org/raspb buster InRelease
Temporary failure resolving 'raspbian.raspberrypi.org'
Err:2 archive.raspberrypi.org/debian buster InRelease
Temporary failure resolving 'archive.raspberrypi.org'
Segmentation faultsts... 99%

Uhhhhh...

@garrett Was that my fault? Oh no. Send me backtraces if it's apt itself that's crashing :D

@juliank I think the Pi is having some other sorts of issues at the moment.

I couldn't do anything else afterward, and I can't ssh back in.

I think I'll hard reset it.

(It's an old Pi 1 on an old SD card. It's not mission critical; I have backup DNS too. Things can and do go wrong once in a while. I'm 99% sure it's not apt. 😉 )

@juliank I figured out the problem. I'm happy to report that it's definitely not apt.

Details (which you can totally skip):

My Pi 1 (it's old) is stuck on a kernel that has buggy zram. Attempting to update it either causes crashes with apt (with swap on) or is extremely slow (with swap off, as there's really not much RAM).

Meanwhile, I'm upgrading the kernel to what should be a non-buggy version and will try again for everything else. If it doesn't work; I'm swapping up to an old Pi 3.

@garrett do you use cloudflared and pivpn with your pihole? I recently got into the whole thing and am still figuring the most refined solution out.

@Saroufim I'm using dnscrypt-proxy on openWRT on my router; the pi-hole points to that.

The Pi serves primary DNS for my home network; the fallback DNS server is my router. (And then I flip over to Cloudflare if anything goes wrong with both.)
