I had QGIS version 2.18.14 installed on my ubuntu. Today I wanted to make an update, but some problems came up. So I deleted QGIS and wanted to reinstall it. But everytime I try to reinstall it, this comes up:
The following packages have unmet dependencies:
python-qgis : Depends: libqgis-analysis2.18.15 but it is not going to be installed
Depends: libqgis-server2.18.15 but it is not going to be installed
Recommends: liblwgeom-dev but it is not going to be installed
qgis : Depends: gdal-abi-2-2-2 but it is not installable
Depends: libqgis-analysis2.18.15 but it is not going to be installed
Depends: libqgis-app2.18.15 but it is not going to be installed
Recommends: qgis-plugin-globe but it is not going to be installed
Recommends: qgis-plugin-grass but it is not going to be installed
Recommends: qgis-provider-grass but it is not going to be installed

How can I fix this problem?
