Hi Jenny, I do not think you need to define "SNAP_USER_DATA＂．It is already there. Please check my "hello" example code at https://github.com/liu-xiao-guo/helloworld-demo. After you install the app, you can run the command like:
liuxg@liuxg:~$ hello.env | grep SNAP SNAP_USER_COMMON=/home/liuxg/snap/hello/common SNAP_LIBRARY_PATH=/var/lib/snapd/lib/gl: SNAP_COMMON=/var/snap/hello/common SNAP_USER_DATA=/home/liuxg/snap/hello/x1 SNAP_DATA=/var/snap/hello/x1 SNAP_REVISION=x1 SNAP_NAME=hello SNAP_ARCH=amd64 SNAP_VERSION=1.0 SNAP=/snap/hello/x1 Basically, SNAP_USER_DATA is defined as "/home/liuxg/snap/Your_Package_Name/version_number" Best regards, XiaoGuo On Thu, Aug 25, 2016 at 7:03 PM, Jenny Murphy <[email protected]> wrote: > Hi, > Do I need to define the location of SNAP_USER_DATA.
