It seems my previous message had a mistake in it:
- "Python light" size is about 7.2 MB, while "Python base" size is around 2.2 MB.
- Since on RUT955 there is only 3-4 MB of free space, can be easily installed, while installing "Python light" would require to remove a lot of existing router's functionalities.
In this case reset your device to factory default settings (just in case any important files were deleted, or if any downloaded data is still present in the router) and then try to perform same procedure, but this time use "opkg install python3-base" command.
I will update my above comment to avoid similar confusions in the future. Sorry for this misunderstanding.
