hi dear community 

 

i have a system runningv on banana pi  and i want to update this 

 

see what is currently running 

 

martin@bananapi:~$ l^C
martin@bananapi:~$ lsb_release -a
No LSB modules are available.
Distributor ID:	Ubuntu
Description:	Ubuntu 18.04.1 LTS
Release:	18.04
Codename:	bionic
martin@bananapi:~$ 

 

 

look forward to hear from you 

 

by the way - how to find out which banana pi am on !?

 

I updated from Debian Strech to Buster following the instruction from this post, also in a Banana Pi. I suppose you can move from 18.04 to 20.04 with caveats in the way.

I perform an image backup from the microSD before doing anything.

hello dear Manuti


was  reading out board with the usage of devicetree


 a kernel using this (most arm/arm64)

cat /sys/firmware/devicetree/base/compatible

in my case it shows

 

lemaker,bananapiallwinner,sun7i-a20martin@bananapi:~$ 

 

 

well  what to do if i want to do a fresh os  based on Armbian ?!

I don't understand your question.

 

But you can change the kernel using `armbian-config` tool and after that change repos from Bionic to Focal.

With something like this (CAVEATS THAT IS NOT TESTED BY ME) :

 

cp /etc/apt/sources.list /etc/apt/sources.list.backup

sed -i 's|bionic|focal|g' /etc/apt/sources.list

apt update && apt -y upgrade && apt -y dist-upgrade
