Public bug reported:
On Ubuntu 19.10 the file /usr/share/pkgconfig/bash-completion.pc has
hard-coded values for completionsdir and helpersdir:
# cat /usr/share/pkgconfig/bash-completion.pc
prefix=/usr
compatdir=/etc/bash_completion.d
completionsdir=/usr/share/bash-completion/completions
helpersdir=/usr/share/bash-completion/helpers
whereas in Ubuntu 19.04 it looks like this:
# cat /usr/share/pkgconfig/bash-completion.pc
prefix=/usr
compatdir=/etc/bash_completion.d
completionsdir=${prefix}/share/bash-completion/completions
helpersdir=${prefix}/share/bash-completion/helpers
the problem with the first one is that one cannot override the prefix
variable:
Ubuntu 19.10:
# pkg-config --variable=completionsdir --define-variable=prefix=/other_dir
bash-completion
/usr/share/bash-completion/completions
Ubuntu 19.04:
# pkg-config --variable=completionsdir --define-variable=prefix=/other_dir
bash-completion
/other_dir/share/bash-completion/completions
This is a problem for software that tries to install as a non-root user
software in non-system directories.
The problem is known upstream and has been fixed:
https://github.com/scop/bash-completion/commit/8c5302581ad20954cfa164dcae26f1ed6277dd90#diff-42e567633e7af054a0d01d8f2b93ddf1
Updating the version of bash-completion to 2.10 (https://github.com/scop
/bash-completion/releases/tag/2.10) will help to fix the issue. In the
new version completionsdir is defined in terms of datadir, so a way to
verify that the bug is fixed and one gets the same thing in Ubuntu 19.06
and Ubuntu 19.10 would be:
# pkg-config --variable=completionsdir
--define-variable=datadir=/other_dir/share --define-variable=prefix=/other_dir
bash-completion
/other_dir/share/bash-completion/completions
The currently installed package in my system:
# apt-cache policy bash-completion
