Bug description:
[Impact]
* Breakage of tools expecting the version number or the number to
substantially match the Debian package version.
* May confuse users expecting the version to substantially match the Debian
package version.
* Restores behavior to that provided in Groovy/Hirsute+ and Bionic and prior
releases.
- Focal is the only release affected.
* Backported Debian fix to restore ".tarball-version" file to provide
version information during build.
- Also included the autopkgtests for versioning from the same Debian fix.
[Test Plan]
1) Create a Focal (or derived from Focal) system.
2) Execute "ps --version" or any of the binaries provided by the package
with their respective version flags.
3) Instead of desired output of the version, the output is:
the invoked binary name followed by "from procps-ng UNKNOWN"
Example: "ps from procps-ng UNKNOWN"
[Where problems could occur]
* This fix could cause issues if applications have come to depend on the
incorrect behavior. IE, an application that uses a version string of "UNKNOWN"
as part of a heuristic for identifying a Focal system.
* If the version of procps-ng is incremented, this patch would need to be
updated or removed if it is no longer relevant. Otherwise, an incorrect version
would be reported by the binaries.
[Other Info]
* This change is in Groovy+ and Debian packaging with the same version of
procps-ng.
- Introduced in procps (2:3.3.16-5) unstable in Debian.
[Original Description]
From Linux Lint 20.1, so Focal Fossa 20.04.1
Package procps 2:3.3.16-1ubuntu2
$ LANG=C ps --version
ps from procps-ng UNKNOWN
I don't know if it comes from Ubuntu or upstream.
