Upgrading Ubilinux Debian Wheezy to Jessie

Ubilinux Install and Upgrade Immediately to Jessie

Ubilinux from Emutexlabs isn't really Ubuntu -- It is Debian Wheezy Version 7.x
Start from Ubilinux fresh. Don't install ANY packages yet -- "Mai Kay Kiang" [singlish].

passwd root
(Get wifi working reliably)

Fix: In /etc/avahi/avahi-daemon.conf, add
allow-interfaces=wlan0,eth0

apt-get update
apt-get upgrade
apt-get dist-upgrade
cp /etc/apt/sources.list /etc/apt/sources.list.wheezy
sed -i 's/wheezy/jessie/g' /etc/apt/sources.list
check and comment out in /etc/apt/sources.list
#deb http://ubilinux.org/edison jessie main
apt-get update
apt-get upgrade
apt-get dist-upgrade
reboot
.

Fix: After updating from Wheezy to Jessie, some bootloader u-boot artefacts may exist.

"Expanding" the filesystem

BAD things happen when apt-get command is executed and space on rootfs runs out. So some tweaking of partition management is required. Some directories of rootfs can be moved to /home partition, maximising space for the former.

  • /usr/share
  • /var/cache
  • move /usr/share to /home/share, and relink (to free up partition 1).
  # cd /usr  
  # cp -rp share /home  
  # mv share share.orig  
  # ln -sf /home/share  
  [reboot and check]  
  # cd /usr  
  # rm -rf share.orig [Ulp!]

For me, the Australia debian mirror site is good ( nano /etc/apt/sources.list )
deb http://ftp.au.debian.org/debian jessie main contrib non-free
#deb-src http://http.debian.net/debian jessie main contrib non-free

deb http://ftp.au.debian.org/debian jessie-updates main contrib non-free
#deb-src http://http.debian.net/debian jessie-updates main contrib non-free

deb http://security.debian.org/ jessie/updates main contrib non-free

#deb http://ubilinux.org/edison wheezy main

OS Post-Installation and customisations

dpkg-reconfigure tzdata
dpkg-reconfigure locales

  • apt-get installs [I need MD tables here, really]
    sudo
    x11-apps xjed screen
    alsa-utils mpg123 espeak libsndfile1-dev portaudio19-dev
    libv4l-dev
    i2c-tools
    git subversion build-essential cmake
    gcc-arm-none-eabi lpc21k
    .
Audio customisation

nano ~/.asoundrc

pcm.!default sysdefault:Headset

The "Headset" comes from

$ aplay -l
...snip snip...
  Subdevice #6: subdevice #6
  Subdevice #7: subdevice #7
card 1: Headset [Logitech G430 Gaming Headset], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
