It seems that LyX is missing its default classes, which results in lots of messages when starting the application.
In my case, this happens in core-updates using a virtual machine. I can't reproduce this problem in my real machine, maybe because I have some leftovers from previous installations of LyX, I don't know. ## Steps to reproduce 1. guix system vm os-config.scm (with GNOME and LyX) 2. Run the resulting virtual machine 3. Log in to the GNOME desktop 4. Press Alt + F2, type lyx2.3 and hit Enter to start LyX ## Expected result LyX starts without errors and displays the "Welcome to LyX" document. ## Unexpected result A message about a missing a textclass appears: https://multimedialib.files.wordpress.com/2020/05/guix-lyx-no-textclasses-message-2020-05-03-1.png Clicking on "Reconfigure" results in an error message about an article class not found: https://multimedialib.files.wordpress.com/2020/05/guix-lyx-document-class-not-found-error-2020-05-03.png Clicking "Ok" results in another message. This time about Cite engine not available: https://multimedialib.files.wordpress.com/2020/05/guix-lyx-cite-engine-not-available-message-2020-05-03.png Clicking "Ok" here finally takes you to the "Welcome to LyX document". https://multimedialib.files.wordpress.com/2020/05/guix-lyx-welcome-document-2020-05-03.png At this point, however, I don't want to use the application because I would expect many things to fail. I didn't check if there is any workaround (e.g. installing packages that provide the missing classes and cite engine). ## System information ``` $ lyx2.3 --version LyX 2.3.3 (2019-06-10) CMake Build $ LANG=C guix describe Generation 78 May 02 2020 18:00:20 (current) guix 7b07852 repository URL: https://git.savannah.gnu.org/git/guix.git branch: core-updates commit: 7b07852ddb334c92bcef69666f21c599f1f0fa79 sirgazil-x ef6ac93 repository URL: https://gitlab.com/sirgazil/guix-channel-x.git branch: master commit: ef6ac9331a7847fdec6f0eb199524b1b755ba0df ``` --- https://sirgazil.bitbucket.io/
