I didn’t even considered running iTunes on linux too. But after installing linux on my macbook, I realized I need to cancel some apps subscriptions only to realized you have to use either an apple device or iTunes for windows to do that. No option to manage your subscription via web at all! After unsuccessful attempt at running iTunes on linux, I ended up dusting off an old ipad mini 2 from my drawer and cancel the subscription from there (thanks god it can still connect to app store, it’s still on ios 12).
