Unsatisfied dependencies

[Phil]

I can no longer use the application dumphfdl because it can no longer 
find libliquid1 and libliquid-dev. I haven't used dumphfdl for at least 
six months and I'm unable to reinstall libliquid1 and libliquid-dev due 
to unsatisfied dependencies.

I upgraded Xubuntu today from version 25.04 to 25.10 but that hasn't 
solved the problem.

It appears to me that libfec0 is the cause but reinstalling that library 
fails as well.

An Internet search hasn't offered a solution. Can anyone suggest how I 
should proceed?

This is the error message:

Unsatisfied dependencies:
  libliquid-dev : Depends: libliquid1 (= 1.7.0-1) but it is not going to 
be installed
Error: Unable to satisfy dependencies. Reached two conflicting decisions:
    1. libfec0:amd64 is selected for install because:
       1. libliquid-dev:amd64=1.7.0-1 is selected for install
       2. libliquid-dev:amd64 Depends libliquid1 (= 1.7.0-1)
       3. libliquid1:amd64 Depends libfec0
    2. libfec0:amd64 is available in version 1.0-26-gc5d935f-1
       but none of the choices are installable:
       - libfec0:amd64=1.0-26-gc5d935f-1 is not selected for install 
because:
         1. libgcc-s1:i386 is selected for install
         2. libgcc-s1:i386 Depends libc6:i386 (>= 2.35)
         3. libc6:i386 Breaks libfec0 (< 1.0-26-gc5d935f-1+b3)
