I can't find any installation repo for QGIS 2.x. Last week I was able to install QGIS 2 then I wanted to try QGIS 3.x. However I encountered many problem related with netCDF. Ergo, wanted to install QGIS 2.x again.
After deal with many package dependency I uninstalled any package related with "gis" using synaptic package manager. Now I want to install 2.x but I can't find ubuntugis because there is no 2.x version.
I tried qgis.org/ubuntu bionic main etc. but it installed 3.x version.
Is there anyone know?
