I already had armbian buster installed on my nanopi neo core, i recently tried to update and upgrade but here is what m getting: 

 

root@nanopineo:~# apt update
Get:1 http://security.debian.org buster/updates InRelease [65.4 kB]
Get:2 http://httpredir.debian.org/debian buster InRelease [122 kB]
Get:3 http://httpredir.debian.org/debian buster-updates InRelease [51.9 kB]
Hit:5 http://httpredir.debian.org/debian buster-backports InRelease
E: Repository 'http://security.debian.org buster/updates InRelease' changed its 'Suite' value from 'stable' to 'oldstable'
N: This must be accepted explicitly before updates for this repository can be applied. See apt-secure(8) manpage for details.
Do you want to accept these changes and continue updating from this repository? [y/N]

 

the armbian buster image is about 2 years old, 4.19

so should i go for the newer images such as focal? or what should i do?

 

anw when i press Y, then i upgrade. if i rebooted the image then the nanopi is dead. i can not access it anymore as if it is not even booting (i can tell from the BLUE LED which no more blinks)

 

Hook up a serial console to get an idea what is happening inside after upgrade.

focal

Userspace and kernel package are independent. All flavors (Focal, Buster, Bullseye, Hirsute...) of each board share the very same kernel package.

If you do not have a serial console and want to continue using this board you can do that or use armbian-config to freeze firmware packages. This will update userspace (so Buster) packages only.

Moved to Common issues / peer to peer technical support

I tried things from the beginning now it is not even updating!!!!

Fix your DNS settings. As you can see names are not resolving.
