I just launched QGIS3 (2.99) after an sudo apt-get upgrade in Ubuntu 16.04. But I get an error on startup that says:

* Unable To Get Local Issuer Certificate: The issuer certificate of a locally looked up certificate could not be found

Screenshot below:

enter image description here

Is it OK to ignore it or is there something on my Lubuntu that needs to be fixed?

According to the QGIS 3 issues response 17546 (comments)

don't worry about the certificate error on the development version of qgis, press "ignore".

  • This is currently happening to me on the release version...albeit only when downloading through OSGeo4W.
