Hi Tom,
The apt install -f doesn't mean force it means fix broken....if possible.
Doesn't always work, but worth a try.
*-f*, *--fix-broken*
Fix; attempt to correct a system with broken dependencies in place.
This option, when
used with install/remove, can omit any packages to permit APT to
deduce a likely
solution. If packages are specified, these have to completely
correct the problem. The
option is sometimes necessary when running APT for the first time;
APT itself does not
allow broken package dependencies to exist on a system. It is
possible that a system's
dependency structure can be so corrupt as to require manual
intervention (which
usually means using *dpkg* *--remove* to eliminate some of the
offending packages). Use of
this option together with *-m* may produce an error in some
situations. Configuration
Item: APT::Get::Fix-Broken.
