I'm happy to report your guess was correct.
Through no fault of yours
$ apt-get install sagemath
on my computer failed to upgrade the
libgsl23 package to the latest version in
unstable.
Evidently not upgrading compliant dependencies to
their latest available versions is intentional.
But, I'm also happy to report, manually upgrading
it with
$ apt-get install libgsl23
seems to have fixed
> ImportError: /usr/lib/i386-linux-gnu/libgsl.so.23: undefined symbol:
> cblas_ctrmv
That's the good news.
The bad?
$ sage
crashed with a new error.
Toward the end of Sage_crash_report.txt I now see
ImportError:
/usr/lib/python3/dist-packages/sage/libs/gap/element.cpython-37m-i386-linux-gnu.so:
undefined symbol: GAP_EnterStack_
If I understand correctly, it suggests sage
didn't find the symbol
GAP_EnterStack_
which seems to be associated with the GAP computer
algebra system.
Upgrading the following gap packages to their
latest versions in unstable elicited the same
error:
gap-core
gap-smallgrp-extra
gap-design
gap-float
gap-grape
gap-guava
gap-laguna
gap-openmath
gap-radiroot
gap-scscp
gap-sonata
gap-toric
I also checked if the versions of packages owning
files listed in its stack trace were currently in
unstable.
Unless I overlooked something, they are.
If you happen to have the time, and are so
inclined, feel free to share more insight!
The latest Sage_crash_report.txt isi attached to
this email, and hopefully, bug report.
Thanks,
Kingsley
