1. Update repo list of packages via apt-get update

2. If there is still error try to install a package with aptitude. Aptitude can help to solve broken dependencies easily.

Thanks, see Post #6.

Odd. I found this one:
http://cdn-fastly.deb.debian.org/debian … _amd64.deb

Did you update the package list?

apt-get update

Duh, thanks for the Heads Up!

I forgot about trying that. It had been a while since I last checked for upgrades. I just selected the Installed (upgradeable) Status and Marked the associated packages before clicking on the Apply button.

After clicking on the Reload button and a couple of goes at reinstalling the package with the Broken Dependencies and another Reload, I think, the problem was fixed.

It would be good if there was a Setting in Preferences for Synaptic to activate the Reload function when it starts.

Alternatively, what's the output of the commands

uname -a
dpkg --get-selections | grep linux-image

"uname -a" results in the following.

"dpkg --get-selections | grep linux-image" results in the following.

I marked All Upgrades this morning and clicked the Apply button.

There was errors regarding the Linux Image which I thought I had copied but after closing Synaptic there was nothing to paste into a Text Editor.

I tried again and was able to copy the following error.

W: Failed to fetch http://deb.debian.org/debian-security/p … _amd64.deb

The following package is listed as having a Broken Dependency.

linux-image-amd64

It only has 1 dependency listed which is the following.

linux-image-4.9.0-9-amd64

The Enabled Repositories are the following.
