Flatpak bitcoin-core not generating .cookie file I'm using the version of Bitcoin-Qt 0.18.1 that comes with Flatpak. I've looked in the Bitcoin datadir, which is in ~/.var/app/org.bitcoincore.bitcoin-qt/data/ and there isn't any .cookie file there. This is preventing me from running Electrum Personal Server.

My Linux distro is MX Linux.

My bitcoin.conf is empty.
I ran bitcoind from Flatpak and it outputted the .cookie file
