Bug#854881: libstdc++6: please add Breaks: libopenmpi1.6
Package: libstdc++6
Version: 6.3.0-6
Severity: important
Hi,
while analyzing piuparts upgrade logs for jessie->stretch, I came across
several cases where the openmpi stack was kept at the jessie version
(libopenmpi1.6 and friends) instead of being upgraded to libopenmpi2
etc. (See also #851681: apt: fails to find a clean jessie->stretch
upgrade path involving the openmpi stack).
Since I haven't heard from the apt people and I fail to see the actual
reason of this upgrade failure myself, I started looking for a
workaround. Adding a Breaks: libopenmpi1.6 to the high-priority package
libstdc++6 should prevent apt from keeping the old version installed
and therefore ensure upgrading to openmpi 2.0
Please consider this change for your next upload targetting stretch.
Thanks
Andreas
