[Bug 1800330] Re: Doesn't know about acpica-tools (acpidump, acpixtract)

[Brian Murray]

The acpica-tools package can make a change which will allow command-not-
found to recognize acpidump and acpixtract as a command. From command-
not-found-extractor's README.md:

### Cnf-Extra-Commands

A list of comma separated commands to be added. This is useful when
update-alternatives is used but the expression is too complicated
for the extractor to parse it. The extra commands will be just
added to the "commands:" tag in the Commands file.


** Package changed: command-not-found (Ubuntu) => acpica-unix (Ubuntu)
