Error upgrading ansible from existing Ubuntu to PPA

[markfqs]

When upstream ansible Ubuntu package is installed, upgrading to ansible from PPA is not directly possible:

dpkg: error processing archive /var/cache/apt/archives/ansible-core_2.16.5-1ppa~jammy_all.deb (--unpack):
 trying to overwrite '/usr/bin/ansible', which is also in package ansible 2.10.7+merged+base+2.10.8+dfsg-1
dpkg-deb: error: paste subprocess was killed by signal (Broken pipe)

Workarround

The obvious workarround is to previosuly uninstall the Ubuntu ansible package version installed.

Proposed fix

Usually packages take care of 'obselting' previous versions or at tag them as mutually exclusive/incompatible so package manager takes care of that during install to avoid conflicts.
