[Qgis-user] Couldn't load SIP module

[Pedro Ferreira]

Hi
Had a problem similar last week after upgrading from QGIS 3.14 to 3.16 on my
Linux Mint 19.3 machine. The problem I had was If I needed to opening
properties dialogue for raster, QGIS ended up crashing. After a couple of
tries removing and reinstalling I've ended up with the SIP error. After
reeding this post https://github.com/qgis/QGIS/issues/39628 I've found out
that it could be a Py-Qt5 problem. I've done this:

1. Purged QT5 along with QGIS;
2. In terminal
sudo apt install gnupg and software-properties-common
sudo apt install qgis qgis-plugin-grass
sudo add-apt-repository ppa:beineri/opt-qt-5.14.2-bionic
sudo apt update
sudo apt install qt514-meta-full 
source /opt/qt514/bin/qt514-env.sh
qgis

Hope it helps you.
Pedro
