Hmmm, never used the pk2cmd tool - I notice there is no GUI based=20
PicKit2 software for Linux.
In any case, the pk2cmd sounds like it should be able to do what you=20
want here - not sure why the verification would not work unless you only=20
program all at once - though I think it's likely to be something you are=20
doing wrong, as I can't imagine a bug like that staying around for very=20
long..
Have you checked the pk2cmd manual (I guess you have) to see if it has=20
any relevant info?
I take it you have the PIC setup okay, with bypass caps and so on?

Sorry can't be of much more help, I only know how to do it on Windows.. :-)
I may download and have a look at the pk2cmd on here when I have a=20
moment - will get back to you if I discover anything.
If not, pretty sure someone else here will know more and will chip in soon.
