Trying to setup a development environment as described in

apt-get install cifs-utils python python-pip python3 python3-pip

Hinweis: »python-is-python2« wird an Stelle von »python« gewählt.
Paket python-pip ist nicht verfügbar, wird aber von einem anderen Paket
referenziert. Das kann heißen, dass das Paket fehlt, dass es abgelöst
wurde oder nur aus einer anderen Quelle verfügbar ist.
Doch die folgenden Pakete ersetzen es:
python3-pip

E: Für Paket »python-pip« existiert kein Installationskandidat.

cd pkgscripts-ng/

git checkout DSM7.0

./EnvDeploy -v 7.0 -p avoton

Full stop.

This is an an Ubuntu 21.-10 system.

Please note that using python for anything will grant to give you errors like this.

Hey, I had a similar problem and the issue is the include/toolkit.config file. Just add a line like this:

AvailablePlatform_7_0="avoton"

I already checked on https://sourceforge.net/projects/dsgpl/files/toolkit/DSM7.0/ if this actually exists and it does.

I would make a pull request, but I barely have any time at the moment and pull requests don't seem to be accepted for the past year.
(This is not a guarantee that it will work, but it might.)
(And maybe make sure your error messages are in English. This way you will be able to find help much quicker online.)
