libsane-common and sane-utils are are hold back on d-u

[vilde]

That was not the problem - libsane is fine, the backends was not - if i remember correctly

This is OT, and I will expose my little knowledge of the vocabulary and programming,  but what is backends? Is it the applications that use (in this case) libsane or what?

Hi,
backend does the work, is where the magic happens. Frontend is for the user interaction.

Normally i don't answer in threads that contain the word fix in hyphens - if one would take the time to read and understand the linked bug one would mention that apt might need a little bit help.

Code Auswählen Erweitern


apt dist-upgrade libsane+


Easy, isn't it? Reason: libsane is a bit messed up - that means half of the packages need libsane the other half need libsane1. Things are a bit worse as libsane1 provide libsane - this is exactly the reason for the need of libsane+

We will see how and when this is fixed in debian, until then i decided to roll the needed packages back to libsane as dependency. It might be that i missed one or two packages, if so, please drop a line here.

@jure, nice finding, had some problems to rebuild the package, missed dependency in d/control

Will upload a fixed version to fixes soon. Thanks.
