ERROR: Cannot install conan==1.48.1 because these package versions have conflicting dependencies.

The conflict is caused by:
    conan 1.48.1 depends on Jinja2<4.0.0 and >=3.0
    conan 1.48.1 depends on Jinja2<3.0.0 and >=2.9

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

ERROR: ResolutionImpossible: for help visit https://pip.pypa.io/en/latest/topics/dependency-resolution/#dealing-with-dependency-conflicts

So I am not sure how to sort out this one. I do not have Jinjia2 installed, but there’s no version that would satisfy the requirement.

The conflict is caused by:
    conan 1.48.1 depends on Jinja2<4.0.0 and >=3.0
    conan 1.48.1 depends on Jinja2<3.0.0 and >=2.9

I tried to install from the DEB but it installs version 1.45, which is too old for me.

Well, I cannot explain it either but I confirm that also the link at https://conan.io/downloads.html provides now the 1.48.1 version. All good, thanks again for the help.

In case you need to explore more the issue I experienced installing it via Python please feel free to drop me a line.

I could get away with conan 1.47.0. This seems to be related to the version of openssl that has been recently upgraded due to a vulnerabilty.

$home/.conan/data/openssl/1.1.1n/_/_/export/conanfile.py': Current Conan version (1.45.0) does not satisfy the defined one (>=1.47.0).
