I have tried 3 different laptops with 3 different distro's. Ubuntu 16.04.1, Ubuntu 16.04.3 and Linux Mint 17. Also I've tried about 8 different kernels.
For that reason, a bug report with apport-collect, containing all my hardware serials and stored wifi connections, seems irrelevant. I'm marking this bug confirmed, as instructed by the Kernel Bot. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed ** Description changed: - I have two systems that have a Dropbox folder synced.
