How to install the required dependencies and algorithms on a NextCloud Snap ?

[moutasem1989]

Describe the bug First install of the MediaDC requires Python dependecies that are not installed: I am running on a Snap version of NextCloud. When I run MediaDC it premotes me to Configure application dependencies on Configuration page. however, on the Configuration page, MediaDC is inable of installing the required dependencies. Nextcloud Log: Error | mediadc | [AppUpdateStep] Python dependencies updating error: {"success":false,"installed":false,"required":null,"video_required":null,"optional":null,"boost":null,"available_algorithms":null,"installed_list":null,"errors":["Cant run pip after local install."],"warnings":null}

To Reproduce Steps to reproduce the behavior:

1. get and run NextCloud from Snap
2. install and run MediaDC
3. try to add the required dependencies.

Expected behavior dependencies are installed when clicking Install.

@moutasem1989 Hi, we don't support snap, until the cloud_py_api framework is released and MediaDC migrated to use it.

[moutasem1989]

@andrey18106 is there a timeframe for that? Thank you again for the great job !

[andrey18106]

@moutasem1989 There is no timeframe, as soon as it's ready) We're working on it, but generally planning migration to using of framework for MediaDC 0.2.0-0.2.1 release.
