Comment 2 for bug 1800330

I believe this is because the package acpica-tools uses alternatives and the commands provided by the package actually have different names.

update-alternatives: using /usr/bin/acpixtract-acpica to provide /usr/bin/acpixtract (acpixtract) in auto mode
update-alternatives: using /usr/bin/acpidump-acpica to provide /usr/bin/acpidump (acpidump) in auto mode
(eoan-amd64)root@impulse:/home/bdmurray/source-trees/cpc_build_tools/human_scripts# dpkg -L acpica-tools
/.
/usr
/usr/bin
/usr/bin/acpibin
/usr/bin/acpidump-acpica
/usr/bin/acpiexec
/usr/bin/acpihelp
/usr/bin/acpinames
/usr/bin/acpisrc
/usr/bin/acpixtract-acpica
...

 $ acpidump-acpica

Command 'acpidump-acpica' not found, but can be installed with:

sudo apt install acpica-tools
