The package 2-3-2..in 18.04 for UBUNTU is simply unusable. I have used LYX for
many years with success and without any problems - finding it easy & most
pleasant to use. I have dozens of LYX files, Two i use a lot I have problems
with (maybe with others too!). Other users had this problem too and I was
recommended to install an earlier version. I chose the suggested 'artful'
version. 2.3.1-2 and installed it successfully. This has partially worked. It
displays now most of my .lyx files properly (but not all) It seems i can modify
those that display but i cannot output them in anyway! neither to printer nor
PDF format (which i prefer) for example It told me i would need book.cls and
scrbook.cls - i found these are apparently covered by cntperchap.zip, which i
have downloaded, but i have no idea how to install it - your doc is far too
complicated for me - more interested in what its all about rather than
installation!. It also told me i would need fancyhdr.sty & enumitem.sty which i
cannot find so far. Please. Can someone tell me (a layman) simply how to find
& install these missing items. Alternatively If i have installed the wrong LYX
version or please tell me? Alternatively if UBUNTU is the problem - (which i
am finding difficult to use with their now very limited availability of
packages for installation) - now no longer suitable? I had tried UBUNTU but was
forced to revert to KUBUNTU (which i achieved with dogged determination and
days of effort) but i'm still having problems installing what i need. i'm
guessing that i cannot be the only one in these difficulties. Best Regards,
David Hewlett. .
