Maybe this should go to support, but this might also be an issue with

Tar version: 1.31

Adding -v to the command, the output is just:

shows that all paths begin with ./ and that all directories (including
./)
have mode drwxr-sr-x. So the set-group-id flag might be the culprit.
I've tried --no-same-permission, to no avail.
using --strip-components=1 allows the files to be extracted, but the
set-group-id flag is set on the extracted files.
If I run the command with these 2 switches: --strip-components=1
--no-same-permission and remove the -C /usr/share/man (that is extract
to the
current directory), it works, and the extracted files have the right
permissions (drwxr-xr-x) and owner root:root. But if I run the same
command
again (that is, now man[157] exists), the command aborts.
But with the /usr/share/man, the command still aborts!
The only way I've found to install the man pages (besides installing
asciidoc
and generating them) is to extract them as a user to the current
directory,
chown them to root:root, and copy them to where they belong.
specifically:
install -dvm 755 man
tar -xf ../git-manpages-2.20.1.tar.xz -C man
chown -Rv root:root man
cp -Rv man /usr/share
This is an issue with tar-1.31. I am using the current instructions
without problem with tar-1.30.

Apparently a workaround is using the -U option until the next tar release.
No it still fails with -U. Here is the fix:
diff --git a/src/extract.c b/src/extract.c
