Hi guys, this is very possibly a duplicate of #1483615 the error is probably due to an issue retrieving a string, and not handled in the driver code. To confirm, please start the driver in debug mode using (as root): /lib/nut/usbhid-ups -u nut -DDD -a myups then /lib/nut/usbhid-ups -u root -DDD -a myups
if confirmed, this was fixed upstream: https://github.com/networkupstools/nut/commit/f679a2820e49cbdec4138295de5e8947ee953a8a However, as mentioned in the other ticket, the above fix has some negative impact. this may in the end be due to another ticket (tied to udev and privileges application) logged by Charles Lepple. This privileges issues could lead to the string retrieval issue, causing these bugs. All in all, adding the patch has more benefits than drawbacks -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1647088 Title: NUT not work with apc backups with usb through usbhid-ups To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nut/+bug/1647088/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
