I was asked by a friend to get Netflix working on his Lubuntu 20.04 Linux laptop. He was running Chromium which comes without Widevine, and the extension wasn't available in the Chrome Web Store, but it can be enabled by simply making libwidevine.so available in Chromium's library path. But how to add a file to the sandboxed lib/ directory of a Snap? You can't without rebuilding the entire Snap as your own custom product, and then it's no longer a standard package from the repo so you lose the blessings of package updates! Maybe there's a better way, but I sure could not find one. I had to ditch Chromium and unfortunately resort to Chrome directly provided by Google, with all of its privacy problems.
