Problems installing postgis and postgresql-16-postgis-3

I have certain problems installing postgis and postgresql-16-postgis-3:

$ sudo apt-get install postgresql-16-postgis-3

Some packages could not be installed. This may mean that you have

The following information may help to resolve the situation:

The following packages have unmet dependencies:
postgresql-16-postgis-3 : Depends: libgdal26 (>= 2.4.0) but it is not
installable
Depends: libjson-c4 (>= 0.13.1) but it is not
installable
Depends: libproj15 (>= 6.1.0) but it is not
installable
E: Unable to correct problems, you have held broken packages.

When I search this package on Ubuntu packages:

so I don't have the option to install a lower version of gdal, but in this
case I need to have the 16th version of postgres.. What could I do?
