Dear Maintainer, I saw the "--cli-version" option in NEWS.Debian.gz. So I tried it: # apt --cli-version update /usr/include/c++/15/optional:1186: constexpr _Tp& std::optional<_Tp>::operator*() & [with _Tp = long unsigned int]: Assertion 'this->_M_is_engaged()' failed. Aborted apt --cli-version update I'm not sure if I invoked it correctly, as there was no explanation in apt(8).
Well you gave --cli-version the argument update which is not a valid version pattern. Sadly apt(8) doesn't seem to render the common options shared by all programs
