Reading through this guide on resolving file conflicts most of the files are not owned by anything and the /usr/lib/libnsl* files are owned by glibc...

There is no package file for libnsl against which may be the source of errors according to the above linked piece...

$this->bbcode_second_pass_code('', '
# ls -l /var/lib/pacman/local/libnsl-*
ls: cannot access '/var/lib/pacman/local/libnsl-*': No such file or directory
')

Is this an error for such a file not to exist?

I'm tempted to try as advised and remove the files under /usr/include/rpcsvc/ as there is no packages called rpcsvc as far as I can tell.

Unsure how to resolve this correctly, on one system I've tried updating all but libnsl and then tried updating libnsl afterwards but the problem persists of libnsl finding files that already exist.

Any pointers on how to go about resolving this would be appreciated.

Thanks in advance.

Narrowed this down to libnsl being pulled in by python/python2/smbclient and decided to do as advised and move the existing files...

Upgraded fine, not rebooted yet so unsure if this approach is going to introduce problems.

Ran into the same, made it go through by force-updating libnsl first, and then upgrading the rest. Survived a reboot even :)
