Hi, I’m moving my folding-at-home snap to core20 as a base.
However, python got deprecated and is now python2. However, if I add python2 as a stage package, then I’m not able to find its content anywhere. I considered it could have been an issue with dependencies. So I made a part just to pull them all:
python2:
plugin: nil
stage-packages:
- python2
- libpython2-stdlib
- libpython2.7-minimal
- libpython2.7-stdlib
- python2-minimal
- python2.7
- python2.7-minimal
Then I have other parts to require it with after:
# <--- Desktop frontend --->
fahcontrol:
plugin: dump
source: https://download.foldingathome.org/releases/public/release/fahcontrol/debian-stable-64bit/v7.6/latest.deb
source-type: deb
stage-packages:
- libxtst6
- libcanberra-gtk-module
- libatk-adaptor
- libgail-common
after:
- desktop-gtk2
- python2
- python-gtk2
- fahclient
Still building fails with:
Failed to generate snap metadata: The specified command 'desktop-launch python2 $SNAP/usr/bin/FAHControl' defined in the app 'FAHControl' does not exist.
Ensure that 'desktop-launch python2 $SNAP/usr/bin/FAHControl' is installed with the correct path.
As I build with --debug option I get into the snap, and indeed python2 is nowhere to be found:
