Starting with version 2.41 of libcap, the output of the getcap program changed and therefore some existing tests fail when the installed version of libcap is >= 2.41 (the latest version available at the moment is 2.44). The change was made by the following commit of libcap: commit 177cd418031b1acfcf73fe3b1af9f3279828681c Author: Andrew G. Morgan <morgan@kernel.org> Date: Tue Jul 21 22:58:05 2020 -0700 A more compact form for the text representation of capabilities. While this does not change anything about the supported range of equivalent text specifications for capabilities, as accepted by cap_from_text(), this does alter the preferred output format of cap_to_text() to be two characters shorter in most cases. That is, what used to be summarized as: "= cap_foo+..." is now converted to the equivalent text: "cap_foo=..." which is also more intuitive. So add a filter to change the old format to the new one, an helper that calls getcap with that filter, make existing tests use the new helper and update their golden output to match the new output format of getcap.
