Dear Maintainer,
When running sage, there is an ImportError related to libsingular-
Singular-4.3.1.so (full trace below). From what I can see, python3-sage depends
on libsingular4m3n0:
$ apt depends python3-sage | grep libsingular
Depends: libsingular4m3n0 (>= 1:4.3.1-p3+ds)
Depends: libsingular4-dev (>= 1:4.2.1-p2+ds-3)
but the library provided by package libsingular4m3n0 is libsingular-
Singular-4.3.2.so instead (that is, 4.3.2 instead of 4.3.1):
$ dpkg -L libsingular4m3n0 | grep .so
/usr/lib/x86_64-linux-gnu/libsingular-Singular-4.3.2.so
/usr/lib/x86_64-linux-gnu/libsingular-factory-4.3.2.so
/usr/lib/x86_64-linux-gnu/libsingular-omalloc-4.3.2+0.9.6.so
/usr/lib/x86_64-linux-gnu/libsingular-polys-4.3.2.so
/usr/lib/x86_64-linux-gnu/libsingular-resources-4.3.2.so
And here is the full trace:

Dear Maintainer,
When I run sagemath here, I get:

ImportError: libsingular-Singular-4.3.1.so: cannot open shared object file: No such file or directory
I just reported a bug on libsingular, but now it is clear that sage calls a version of it (4.3.1) that is no longer available after the upgrade (4.3.2 is the one installed). Is it only a matter of update the version of this dependency?
Best, Alexandre.
Dear Maintainer, sagemath can't be run here. After many messages, the last one is: ImportError: libsingular-Singular-4.3.1.so: cannot open shared object file: No such file or directory Maybe it can be fixed by invoking the currently installed version of libsingular. Or is it more complicated than that? Best, Alexandre
Hello, I would like to confirm this bug and add that on a Sid system, sagemath seems to block upgrades. And the following command might give a clue as to why (I have no held packages):--- # apt-get install sagemath Reading package lists... Done Building dependency tree... Done Reading state information... Done sagemath is already the newest version (9.5-6). Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: libsingular4m4n0 : Conflicts: libsingular4m3n0 (> 4.4.0) E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages. --- Respectfully, G.raud
