deCONZ stopped working after 6.27.2 update

Hi folks,
I have a RPi 3A+ that I use with dietpi to mainly run my smart home devices, using homebridge.
Everything has worked great so far, but after the 6.27.2 update my ConBeeII USB dongle has stopped working.
I tried to update its firmware, but when I run the

sudo GCFFlasher_internal -d /dev/ttyACM0 -f deCONZ_ConBeeII_0x26490700.bin.GCF

I end up getting

/usr/bin/GCFFlasher_internal.bin: /lib/arm-linux-gnueabihf/ version `GLIBC_2.28' not found (required by /usr/lib/

can you help me fixing this?
