qgis container not working out of the box?

[Robinlovelace]

I've tried a session starting with our qgis container and get an error:

docker run -it ghcr.io/geocompx/docker:qgis /bin/bash
R
library(qgisprocess)

>>> PROBLEM encountered: couldn't build and save package cache! 

Any ideas @jannes-m ?

>>> PROBLEM encountered: couldn't build and save package cache! <<<
The 'qgis_process' command-line utility was either not found or
did not fulfil the needs to build the package cache.
Please run `qgis_configure()` to fix this and rebuild the cache.
See its documentation if you need to preset the path of qgis_process.
If the problem persists, make sure that you correctly installed QGIS
for your operating system using the instructions at
<https://download.qgis.org>.

Yeah, I have seen this before. You can run the qgis_process command on the CLI and you will see that there is some output (remember to set one env variable before running it, I don't recall its name from the top of my head) , some uninformative and irrelevant error messages, that makes qgisprocess stop when parsing that output.

[jannes-m]

I will report this back to Floris and then we'll see if and how we can adjust qgis_configure() accordingly. Currently, we are on our way to Croatia but I will find some time in the coming days in the evening to explore this issue further.

Thanks and enjoy the holidays Jannes!
