As best I can tell, asyncore has been deprecated since python3.3 or maybe 3.6....I can't seem to install an older version of python on my fedora vm...

[bg002h]

for a work around on fedora:

sudo dnf install python3.7
python3.7 -m venv env
source env/bin/activate
pip3 install blocksat-cli

This environment at least lets the instructions command to blocksat-cli load

[bg002h]

this only gets one so far...it looks like fedora 39 isn't supported yet...blocksat-cli deps install can't find a repository because fedora-39-x86-64 does not exist in project blockstream/satellite

@bg002h , thanks for reporting the problem.

You are right about asyncore. The issue applies only to the S400 receiver, given that it is the only receiver type for which the CLI uses SNMP for communication. We expect to have a fix for that soon.

As for the RPM package repository, please try now. We already have the packages for Fedora 39.

For now, the Python virtualenv workaround should suffice for running PySNMP (which calls asyncore). Also, you can use any Python version up to 3.11, not necessarily Python 3.7. The asyncore module has been removed on Python 3.12, the Python version that Fedora 39 runs by default.

[blockstreamsatellite]

@bg002h FYI, we have pushed a fix for the asyncore issue you experienced, which was related to the PySNMP package. The changes are already merged into the master branch. Please feel free to try them and let us know if you still have any issues.

Note that, to try this, you need to install the CLI from the source. You can do so on a virtualenv too, as you mentioned earlier. For example:

python3 -m venv .venv
source .venv/bin/activate
make install

Then, you can access blocksat-cli from the virtualenv path:

# Add to path
export PATH=$PATH:$(pwd)/.venv/bin
# Confirm path
which blocksat-cli

things work until trying to configure the s400...
