Bug#964150: petsc: autopkgtest regression: mpiexec was unable to launch the specified application

[Paul Gevers]

Source: petsc
Version: 3.13.2+dfsg1-1
X-Debbugs-CC: debian-ci at lists.debian.org
Severity: serious
User: debian-ci at lists.debian.org
Usertags: regression

Dear maintainer(s),

With a recent upload of petsc the autopkgtest of petsc fails in testing
when that autopkgtest is run with the binary packages of petsc from
unstable. It passes when run with only packages from testing. In tabular
form:

                       pass            fail
petsc                  from testing    3.13.2+dfsg1-1
all others             from testing    from testing

I copied some of the output at the bottom of this report.

Currently this regression is blocking the migration to testing [1]. Can
you please investigate the situation and fix it?
