Upgrade Ubuntu 6.06 LTS to Ubuntu 8.04 LTS
Install all 6.06 updates and reboot:
aptitude update aptitude dist-upgrade reboot
Install the update manager:
aptitude install update-manager-core python-apt python-gnupginterface python2.4-apt
Then initiate the upgrade. It is suggested to run this from a console, not via SSH:
- I took the default answers most of the time.
- Whole process took a few hours to download and install stuff. Would have to periodically check progress and answer prompts, so it was not completely automated, and this made the upgrade slower.
- Then rebooted when prompted at the end.
- Booted the new kernel, and the system was now Ubuntu 8.04 LTS.
- Then did again:
aptitude update aptitude upgrade
... this removed a few no longer needed packages left over from 6.06.
Tweaks for clean bootup
Then checked the boot messages, and removed some packages that were not starting correctly and were no longer needed, or tweaked their config files to remove errors. Your tweaks required may differ:
aptitude remove nstx nano /etc/smartd.conf
... and commented out the "DEVICESCAN" Line
- Added 2 powertop bootup lines to end of /etc/rc.local to reduce power usage:
# Power savings, as per powertop suggestions: echo 1 > /sys/module/snd_ac97_codec/parameters/power_save echo 1500 > /proc/sys/vm/dirty_writeback_centisecs
... and confirmed that the bootup was clean and everything required was starting correctly, and that was it!
