I can't reproduce this issue on my system unless I forcibly remove the device (or suspend as commented by komputes), on the other hand, it happens as well in nautilus, which leads me to believe the issue lies in udisks rather than cryptsetup or elsewhere.
I can also see that udisks doesn't seem (to me at least) to do things right, searching through all devices' properties to look for the one that has the removed device as slave, when these properties have already been updated and removed. Since I was able to write a patch that seems to me like it's fixing the issue for both use cases (nautilus/palimpsest and suspend), I'm adding a task for udisks (and I pushed the patch upstream for review). ** Bug watch added: freedesktop.org Bugzilla #30332 http://bugs.freedesktop.org/show_bug.cgi?id=30332 ** Also affects: udisks via http://bugs.freedesktop.org/show_bug.cgi?id=30332 Importance: Unknown Status: Unknown ** Also affects: udisks (Ubuntu) Importance: Undecided Status: New -- Plugging in a LUKS device causes the following error: Error unlocking device: cryptsetup exited with exit code 239: Command failed: Device already exists https://bugs.launchpad.net/bugs/484429 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
