[QGIS-it-user] Installazione QGIS Server su Ubuntu 16 xenial

[Federico Gianoli]

Carissimi,
sto riscontrando diversi problemi ad installare QGIS Server 3.4 su un
server con ubuntu 16 xenial.

Ho aggiunto i seguenti repository a /etc/apt/sources.list

deb http://qgis.org/ubuntugis-ltr xenial main
deb-src http://qgis.org/ubuntugis-ltr xenial main

Con questi aggiunti, col comando apt-cache policy qgis-server mi individua
correttamente la versione 3.4.5+24xenial-ubuntugis
ma quando gli dico di installare mi lascia questi errori

# apt-get -y install qgis-server python-qgis

Ho provato ad installare manualmente ma non le trova, gli stessi errori li
ho anche se provo ad installare qgis.
Qualcuno ha sperimentato gli stessi errori?

Ho fatto la stessa installazione anche su un server ubuntu 18 bionic ed è
filata liscissima, purtoppo non posso fare l'upgrade di ubuntu 16.

Grazie mille

Federico
