Package: fish-common Version: 3.1.2-3 Severity: normal The pkgconfig file fish.pc lists prefix=/usr datadir=/usr/share completionsdir=/usr/local/share/fish/vendor_completions.d functionsdir=/usr/local/share/fish/vendor_functions.d confdir=/usr/local/share/fish/vendor_conf.d I think that the /usr/local part should be replaced by /usr, otherwise packages that depend on fish.pc to get the completions directory will install into /usr/local, which is a no-go in Debian.
Futhermore, the variable $fish_completion_path still lists loads of flatpak directories, which are not available in Debian, and should preferrably be removed.
