Not exactly, but did you add the ubuntu-gis non-ltr ppa?

Below is my qgis.list with all entries to quickly change between LTR and
3.4 versions by switching
deb https://qgis.org/ubuntugis xenial main
vs.
deb https://qgis.org/ubuntugis-ltr xenial main

You need also to change xenial to bionic everywhere.

After changing the following should remove the deps properly and
reinstall the new version:

apt update
apt remove qgis-common python-qgis qgis-providers-common
python-qgis-common qgis-provid
er-grass
apt autoremove
apt install qgis python-qgis qgis-provider-grass qgis-providers
