Micro:bit set up

[Valtam]

Regarding ppa:pmiller-opensource/ppa, there is no Xenial (3.x Series) repo so thats why you're getting an error there on that particular repo.

Mu - that file is 64bit, you need to be on 64bit LL for it to work.

Code:

jerry@z800:~$ file mu-0.9.13.linux.bin
mu-0.9.13.linux.bin: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=dcb7928ff5bfd3f1de0f2f774950cd22212132c1, stripped

dialout group - you need to add your user to this in Lite User Manager, then logout/in.
