package libxslt1-dev 1.1.26-8ubuntu1 failed to install/upgrade: './usr/bin/xslt-config' is different from the same file on the system

[George Masters]

[rational]
libxslt1-dev is architecture specific, so shouldn't be marked for multi-arch.

[test case]
Try to install both libxslt1-dev:i386 and libxslt1-dev:amd64, apt should refuse to let you do that.

In the past it'd be allowed and would fail to install.

[regression potential]
If something depends on these being co-installable, it's already broken anyway, so won't be any worse.

I was installing the Koha Integrated Library System 3.8.1 Within this package is a list of packages to install using dpkg and dselect.

The steps in the Koha documentation are:

From the Koha 3.8.1 directory:

sudo dpkg --set-selections<install_mis/ubuntu.packages

the
sudo dselect

WIthin dselect select [I]Install to tinstall the packages. It did not finish installing all the packages when this particular file failed as referenced in the summary. Had it installed the next setp would be to [Q]uit
