I am on Linux Mint 17, using the lyx-devel/release ppa. When I tried to install the regular system updates today using the update manager, it failed with the message,
E:/var/cache/apt/archives/lyx_2.2.0-1~trusty~ppa3_amd64.deb: trying to overwrite '/usr/share/icons/hicolor/scalable/apps/lyx.svg', which is also in package lyx-common 2.1.4-1~trusty~ppa1 I'm not sure I understand what exactly the problem is or was, but I resolved the problem by running. sudo apt-get remove lyx sudo apt-get upgrade sudo apt-get autoremove sudo apt-get update sudo apt-get install lyx I hope this helps in case anyone else runs into this same issue, and I also hope that perhaps we can understand better what went wrong to avoid it in the future.
