So right now no ways to update from Bionic?

Something went wrong 5.4.85-sunxi not deprecated, so looks weird pi@orangepipcplus:~$ apt list --installed | grep linux binutils-arm-linux-gnueabihf/bionic-security,bionic-updates,now 2.30-21ubuntu1~18.04.8 armhf [installed,automatic] console-setup-linux/bionic-updates,now 1.178ubuntu2.9 all [installed] libselinux1/bionic,now 2.7-2build2 armhf [installed] linux-base/bionic-updates,now 4.5ubuntu1.7 all [installed] linux-bionic-root-legacy-orangepipcplus/now 20.11.6 armhf [installed,local] linux-dtb-legacy-sunxi/now 20.11.6 armhf [installed,local] linux-image-legacy-sunxi/now 20.11.6 armhf [installed,local] linux-libc-dev/bionic-security,bionic-updates,now 4.15.0-204.215 armhf [installed,automatic] linux-u-boot-orangepipcplus-legacy/now 20.11.6 armhf [installed,local] util-linux/bionic-security,bionic-updates,now 2.31.1-0.4ubuntu3.7 armhf [installed] pi@orangepipcplus:~$ sudo apt install linux-dtb-current-sunxi64 linux-image-current-sunxi64 E: Unable to locate package linux-dtb-current-sunxi64 E: Unable to locate package linux-image-current-sunxi64

Few years ago I setup armbian with 5.4.85 kernel. now try to update from instructions: sudo apt update sudo apt upgrade sudo armbian-config System->Other and got "No other kernels available!" Googling this error didn't help, and worst that I can't now install kernel headers Is there some update to current kernel (5.15) from bash? or linux build in common
