Thanks @tudorbarascu, but follow qgis.org instruction key come from qgis.org site, is it correct?

While at it, I don't understand the difference beetween Dockerfile.g3wsuite-deps.dockerfile and Dockerfile.g3wsuite-deps.dockerfile and Dockerfile.g3wsuite-deps.ltr.dockerfile as they're the same, so why should both be kept?

Simple @tudorbarascu, g3w-suite-deps il for last QGIS version available, now is 3.26 instead ltr is for last fersion for QGIS LTR edition 3.22. Into Continue Integration no LTR version is used to test with new API.

Yes, that's the general instruction for linux. It seems that Tim puts all the time the new key to the keyserver.ubuntu.com as you can see from https://keyserver.ubuntu.com/pks/lookup?search=qgis.org&fingerprint=on&op=index

So for ubuntu the key steps are easier and as the docker images are for ubuntu I thought its simpler as it was before. Thank you
