How it is checked
Audit method: Shell command
alt0() { command -v gsettings >/dev/null 2>&1 || { echo "step1: gsettings not installed"; return 1; }; o=$(bash -c 'gsettings writable org.gnome.desktop.media-handling autorun-never' 2>&1); printf '%s\n' "$o" | tr -s ' \t' ' ' | sed 's/^ //;s/ $//' | grep -Fxq -- false || { echo step1: missing false; return 1; }; command -v gsettings >/dev/null 2>&1 || { echo "step2: gsettings not installed"; return 1; }; o=$(bash -c 'gsettings get org.gnome.desktop.media-handling autorun-never' 2>&1); printf '%s\n' "$o" | tr -s ' \t' ' ' | sed 's/^ //;s/ $//' | grep -Fxq -- true || { echo step2: missing true; return 1; }; }; if alt0; then echo compliant; fi- Expected output

Run the following command to create the /etc/dconf/db/local.d/ and /etc/dconf/db/local.d/locks/ directories if either does not exist: # [ ! -d "/etc/dconf/db/local.d/locks/" ] && mkdir -p /etc/dconf/db/local.d/locks/ 3.
