In app shop linux mint as Electrum is only Electrum-GRS (org.groestlcoin.electrum-grs) is Your Electrum org or is scam?
That's a fork of Electrum but instead for Bitcoin, it for an Altcoin "
Groestlcoin".
It's not created by the original Electrum developers since they are only working on the official Bitcoin version: "
Electrum".
But it's not necessarily a scam, it designed for that particular Altcoin but it wont work if your use-case is to send and receive bitcoins.
