Package: arduino Version: 2:1.0.5+dfsg2-4.1 Followup-For: Bug #894823 I just realized this is a duplicate of ##894769.
BTW it's not a user permission problem. I've used arduino before on the same PC with no problems and permissions are fine (dialout). -- System Information: Debian Release: buster/sid APT prefers unstable APT policy: (500, 'unstable'), (500, 'testing'), (500, 'stable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.15.0-2-amd64 (SMP w/4 CPU cores) Locale: LANG=it_IT.utf8, LC_CTYPE=it_IT.utf8 (charmap=UTF-8), LANGUAGE=it_IT.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages arduino depends on: ii arduino-core 2:1.0.5+dfsg2-4.1 ii default-jre [java6-runtime] 2:1.9-63 ii libjna-java 4.5.1-1 ii librxtx-java 2.2pre2+dfsg1-1 ii openjdk-8-jre [java6-runtime] 8u162-b12-1 ii openjdk-9-jre [java6-runtime] 9.0.4+12-4 Versions of packages arduino recommends: ii extra-xdg-menus 1.0-4 ii policykit-1 0.105-20 arduino suggests no packages. -- no debconf information
