Beginner Questions: connection reset by peer

Installation
1

Today i installed HomeAssitant on a old Raspberry Pi3b with the image from GitHub. I know, that this is not the fastest device but i try to only play with the instance and maybe replace other solutions like Goggle Home later with a more performant hardware. Anyway, i could create a SD Card with ISO Image Writer on KDE, installed the OS and could boot the whole thing. I have configured WiFi and im able to login at http://homeassistant:8123/ with my browser. I have a Update from Home Assitant supervisor 2026.02.1 to 2026.03.2 and need to process this. If i try to update this via the browser, i run in to a timeout every time. Searching the Internet gives me a command i could try on the console “ha supervisor update” but it seems that this also timeouts.

Since this is my first time using this HomeAssitant thing, i dont know anything. I hoped, that i could see more output or some errors, when i use the command line. But all what i see is “Processing…” and later on "Processing... Done" Error Update of Supervisor failed: failed to copy: read tcp 192.168.178.3:52902->185.199.109.154:443: read: connection reset by peer

Where do i find some logfiles to see whats going on or where it fails or a more detailed output of the command itself?

Not enough memory, not enough speed.
I suggest since it is for testing only stick with the rev you have working, otherwise get something with a little more power.

Are you sure that connection reset by peer occur because of the memory consumption? I can try a VM on my laptop, here i could extend the memory to 4GB and more (like on a RPi 4/5). My idea was it, to test, if the whole thing is what i want. After that, move on to a better and more powerful device and restore the config there (if possible). The current 3b is only for testing purposes. I dont want to keep this as the final solution.

I’m sure that the potential is high that the 1gb memory in a pi3b is sketchy and has a high possibility of causing problems.

OK. I will try to find a way to raise the swap space, before i change the hardware. Maybe this helps a little bit.

Sure, but swap space on an SD card is 1, VERY slow, and 2, wearing out the sdcard at a ridiculous rate.

Yepp, I know but this is only for testing, before I switch to better performing hardware. I don’t if this will be another RPi 4 or HA green device. Since this device should only run HA, it doesn’t matter if this has more than 4GB of RAM or more hdd space. All backup data will send to my main RPi (8GB), which already functions as a backup target for all other laptops and pc’s at home. This is a Linux only household here. PC’s and Laptops run on Arch or CachyOS and servers on Debian. Phones on GrapheneOS. Backup is easy via rsync and SFTP.

Only these HA thing is new for me. But I don’t want to double use the underlying Debian for anything else as HA.
