Not new to Latex, been using it for years and after writing my dissertation I think I know quite a bit about what's going on. Joined the forum since I realised you can always know more and learn new tricks

Anyway, I just set up Texmaker on my pc. Previously had it installed in Windows 7 and now in Ubuntu... previously it would automatically offer to download any packages I did not have. Now it just crashes...
Does anyone know how to set this? Looked through the config and user manual and didn't find anything...
Thanks
