Synaptic problem(s)

[Richard Owlett <rowlett@access.net>]

Running Debian 12.7 with MATE
When launching Synaptic I get a message saying
  [ You have 1 broken package on your system!"
    Use the "Broken" filter to locate it.       ]
Synaptic's Help isn't helpful :{
It also reports packages to be updated.

Also started to install gnumeric and it wanted to remove some files I 
associate with printer drivers and also ghostscript.

To investigate I searched for it and Synaptic had a red filled box to 
the left of its name.

I did a power off/on restart. Still the same.

What should I do now?
I suspect using apt &/or cousins would be more informative.\
Never used them.

Help please.
