Somewhere in the 2.3 to 2.5 time frame the step timing numbers changed from base thread periods to nS
This may account for the Gecko timing difficulties

UPDATE: followed the instructions to upgrade 2.4 to 2.5. Ran into a problem.

It's telling me that 2.5 has some Ubuntu dependencies that are not installed -- libtk-img, python, stuff like that -- probably because I skipped the Ubuntu upgrades to save time !!!! :P

Sooooo .... I'm going to do those Ubuntu upgrades using the "old-releases" sources, and then give 2.5 another go.

UPDATE: I successfully upgraded 8.04 to 2.5.4. Here's the important points in case someone else with the same problem stumbles upon this thread:

-- the main Hardy repositories are dead, but the "old-releases" repositories still work as explained by Eric66.

-- it's possible to upgrade 8.04/2.3 to 2.4 without upgrading Hardy's Ubuntu files, but 2.5 won't install without first doing the Hardy Ubuntu upgrades.

-- once you get the Ubuntu upgrade sorted out, 2.5 installs normally. :cheer:
