[Salvatore Bonaccorso]

Package: python3-django-postorius
Version: 1.3.13-1
Severity: serious
Justification: not installable
X-Debbugs-Cc: carnil at debian.org

Hi

python3-django-postorius fails to install in unstable, due to quite
strict dependency on python3-django versions which are not anymore
satisfiable:

root at sid:~# apt-get install python3-django-postorius

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:
 python3-django-postorius : Depends: libjs-jquery (>= 3.6.0) but it is not going to be installed

   1. python3-django-postorius:amd64=1.3.13-1 is selected for install
   2. python3-django-postorius:amd64 Depends python3-django (< 3:4.3)
      but none of the choices are installable:
      [no choices]
