Package: libpng-dev
Version: 1.6.30-2
Severity: important
User: helm...@debian.org
Usertags: rebootstrap
When installing a libpng-dev built with debhelper (<< 10.7) and a
libpng-dev built with debhelper (>= 10.7) together, dpkg errors out:
| Unpacking libpng-dev:mips (1.6.30-2) ...
| dpkg: error processing archive
/tmp/apt-dpkg-install-gmKkex/19-libpng-dev_1.6.30-2_mips.deb (--unpack):
| trying to overwrite shared '/usr/bin/libpng16-config', which is different
from other instances of package libpng-dev:mips
| dpkg-deb: error: subprocess paste was killed by signal (Broken pipe)
libpng-config.in interpolates @includedir@ which happens to be
${prefix}/include on older debhelper releases and /usr/include on newer
ones. Thus the interpolated file differs (in bytes, not in behaviour).
The relevant debhelper change is #813266.
I believe that a good solution to this problem would be adding a version
constraint on debhelper. There are two reasonable choices:
* Build-Depends: debhelper (>= 10.7~)
* Build-Depends: debhelper (<< 10.7~)
The former is useful for unstable and the latter is useful for
backports.
