--- Comment #1 from Gustavo A. Díaz gustavo.diaz@gdnet.com.ar --- Ok, fixed. The problem was that KDE neon modify the file /etc/os-release. The install script run fine since I've modified it (instead of os-releast) from:
case "$ID" in ubuntu|linuxmint|debian)
to:
case "$ID" in ubuntu|linuxmint|debian|neon)
and then I think DRM_VERSION is empty because of modified ID in os-release.
I think there must a way to support this, since KDE Neon is Ubuntu LTS based.
