Unfreeze firmware via armbian-config.

1. Forums language is english. You agreed on that by registration: https://forum.armbian.com/terms
2. https://www.google.com/search?q=raspberry+pi+4+vs+5

They are not compatible and Armbian does not support the Zero3. However support can be added if someone steps up for this task.
Any Armbian images you may find for the Zero3 in the web are not ours.

Then you came to the wrong place. We do not provide support for 3rd party OS.

1. If nobody takes the task to build the necessary packages for Debian this will not get solved anytime soon.
2. Yes because  the ppas are made for Jammy
3. Perhaps but don't know.

Looks like Debian stock kernel which obviously won't work with this board. Try installing wireguard with "--no-install-recommends" switch

There are no packages for 23.05 release at all due to major stability issues.
 I think there aren't older ones either because R6S has been added after 23.02 release.
 
Anyway as you already guessed you can use the build framework to create a package bundle for your board and do whatever you want with them.
Or simply wait a few days until 23.08 release which will have both images and apt repo up to date
 
 

Two options:
- downgrade to 23.02 kernel and grab header from repo
- use the build framework to build a set of firmware packages by yourself which then can be installed via dpkg

Login credentials for genuine Armbian images are always root / 1234
For 3rd party images we cannot help.

Also possible but not recommended. https://docs.armbian.com/User-Guide_Getting-Started/#how-to-upgrade-distribution-like-focal-to-jammy-or-bullseye-to-bookworm
Keep in mind that Bullseye will continue receive userspace upgrades until "roughly July 2024 to June 2026": https://wiki.debian.org/LTS

Correct. Ubuntu and Debian userspaces are incompatible.

code { font-family: Consolas,"courier new"; color: crimson; background-color: rgba(0, 0, 0, 0.2); padding: 2px; font-size: 105%; } dpkg-reconfigure locales to make sure en_US UTF8 is available and set default
code { font-family: Consolas,"courier new"; color: crimson; background-color: rgba(0, 0, 0, 0.2); padding: 2px; font-size: 105%; } dpkg-reconfigure keyboard-configuration should do the rest

Standard comes with all standard tool to be ready to do most common tasks oob.
Minimal comes, as the name implies, with a bare minimum of packages to get a somehow running system.
You can check the build repository on github for package lists.

Armbian does not provide updates for userspace packages. Firmware (u-boot, kernel) however may (or may not) receive further updates until something breaks (and nobody volunteers to fix).

Bullseye images have been replaced in favor of upcoming Bookworm.
All links here working perfectly: https://www.armbian.com/orangepi-r1plus-lts/
You can build your own image with Bullseye userspace if you want: https://docs.armbian.com/Developer-Guide_Build-Preparation/

A backup is the correct option
 

Hm did you run apt update beforehand?
Download works for me
 
apt-get download linux-headers-current-sunxi Get:1 http://fi.mirror.armbian.de/apt buster/main armhf linux-headers-current-sunxi armhf 23.02.2 [12.0 MB] Fetched 12.0 MB in 4s (3,045 kB/s)  

Two ways:
Get a UART serial adapter and use debug console to get in
get an eMMC-USB adapter to mount it on a different computer and restore functionality.
 
Also worth a try: write a fresh image to an sdcard, plug it in and boot. Ideally it should boot from SD, then mount eMMC and do adjustments.

If not there they are gone.

We only provide a small quantity of image combinations that are possible because building and providing them all would be just insane.
 
Check here for building your own customized image: https://github.com/armbian/build

You cannot install amd64 binaries on arm hardware.

As always the solution pops up once I start complaining
 
Seems like my 64G microSD is cursed. It works well on common usage but it refuses to work properly on SBCs. Not wrote the same image to a 32G SD of same quality and brand and it works...
