Simple Scan doesn't work

[Charles]

The latest version of Simple Scan released for Ubuntu 18.04 LTS does not work. Version 3.28.0-0ubuntu1 is installed. When I click to launch it nothing happens.

I initially reported the bug against Simple Scan, but they said it was a problem with the Ubuntu 18.04 LTS distribution.

Status changed to 'Confirmed' because the bug affects multiple users.

Retasking to the simple-scan package in Ubuntu.

Thank you for your bug report, could you give the output of those commands?

$ which simple-scan
$ ldd -r /usr/bin/simple-scan
$ ls -r /usr/local

the 'error while loading shared libraries: libcolord.so.1' error on the upstream report suggests an issue created by a leftover local installation

Thanks for the response. "Bug" was resolved by Bartosz, reference:
https://bugs.launchpad.net/ubuntu/+source/simple-scan/+bug/1869524

now when I run $ which simple-scan
the result is:
/usr/bin/simple-scan
as expected.
When I run $ ldd -r /usr/bin/simple-scan
