package libsane1 1.0.27-1~experimental2ubuntu2.1 failed to install/upgrade: trying to overwrite shared '/lib/udev/hwdb.d/20-sane.hwdb', which is different from other instances of package libsane1:i386

[Ricky Seltzer]

Just came out of several hours of hibernation and load average was a high 10. It's never that high when I use this fast machine. Htop says big CPU user was Thunderbird.

Before I put the system in hibernation I was trying out Firefox quantum. It seemed nice.
I closed Firefox before going into hibernation.

While typing this apport popped up with a gnome-shell error.

I haven't used the scanner in weeks. And I've rebooted since then.
Using kernel 14.1

Description: Ubuntu 17.10
Release: 17.10

---
Didn't expect a bug report.
It popped up while the system was coming out of hibernation.
