glibc, which as a good administrator you are probably doing by occasionally running
updateon your package manager du jour. The update borks a standard compiled library that the Crashplan electron app needs, namely
libnode.so. It was a pain to work this out because the client’s logging is pretty rubbish. Luckily, the fix turns out to be pretty simple. Just install an electron app that isn’t a pile of garbage; like Github’s Atom editor, then copy its
libnode.soto your Crashplan’s directory:
sudo mv libnode.so libnode.so.bork
sudo cp /usr/share/atom/libnode.so .
