I've done a really dumb thing: I installed Ubuntu 8.04 on a desktop & told the installer it was an AMD64 machine. The install went fine & most things work. Some don't & that's 'cos it's actually an Intel P4 :{
Is there a simple way to change th architecture, other than a full clean install?
Oh, and in the meantime, I ran the updater & it's now running 9.04.
If get the 9.04 installer & run that on the existing system, will that sort things without losing any changes I've made/software I've installed & customised?
The main problem is that Skype will not install as it, unsurprisingly, complains about "wrong architecture". Also, I can't install some of the stuff needed to display videos in Firefox for the same reason.
Any ideas gratefully received.
