Bug#1001658: singular: cannot upgrade to 1:4.2.1-p2+ds-3

[Patrice Duroux]

Package: singular
Version: 1:4.1.1-p2+ds-4+b3
Severity: wishlist

Dear Maintainer,

Here is what I am getting:

$ sudo LANG=C apt upgrade
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Calculating upgrade... Done
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:
 libsingular4m1 : Breaks: libsingular
E: Broken packages

I do not know also why apt transaction is aborted while there are some
other package to upgrade. Is this also a trouble in apt?

Thanks,
Patrice
