Hello, I would be very grateful if anyone can enlighten me. I am trying to update LyX. The update requires the above libstd... file (?), but when I try to install that I get a load of warnings about it conflicting with a previous version(?)/others already installed, and that a lot of other apps depend on what is already installed. It's looking like updating LyX isn't worth the bother, or even possible without virtually updating everything else as well! Any hints, instructions please. Compared to a year ago I'm having a much better time with Linux, but I'm still pretty ignorant about this kind of thing. Regards, Alisdair.
