General ⇒ Problem with fresh install, several packages unavailable etc

[Thorolw]

I've been using LyX for three months to take notes in lectures, so I'm pretty much self taught and don't really understand the ins and outs of the program completely.

I got a new computer a few days ago and the fresh install won't recognize my old files very well. It kinda works, but I'm getting some errors with it not recognizing document classes, when I check the drop down menu for document class everything is unavailable. I'm also not able to preview the rendered pdfs and many of my commands display differently than they used to, \cdot is rendered as \times for example, and this is only what i found today.

How would i go about copying all the files from my old computer to get an identical setup.

I'm on Linux Mint 17.1 running LyX 2.0.6, same as the old computer.

Welcome to the forum!

LyX is just the frontend. You need to install TeX.

First, an update of package information would be good:

sudo apt-get update

Then, install TeX Live full, if you have more than 3 GB available. So you don't need to worry about missing packages later:

sudo apt-get install texlive-full

Make that in the terminal. This I know from Ubuntu, Mint is derived from it, so it should work the same. Mint may provide another package manager, where you could find texlive-full in the GUI.
