Partly. The iTunes program is Windows and Mac only, but Apple Music runs fully in a browser on Linux, so your subscription, library and playlists all still work. Syncing an iPhone does not.
iTunes by Apple · Music & audio · Only some of it works
Apple offers iTunes downloads for Windows and for older Macs, and says nothing about Linux. On
newer Macs iTunes has already been split into separate Music, TV, Podcasts and Books apps, so the
program itself is being retired anyway.
The part most people actually want does work. The Apple Music web player at music.apple.com opens
in Firefox or Chrome on Linux, signs in with your Apple Account, and gives you your library,
playlists, radio stations and downloads-for-streaming. You can pin it to your taskbar so it opens
like an app. Apple TV content also plays in a browser.
Two things do not work. Backing up and syncing an iPhone or iPad over a cable is an iTunes and
Finder job with no Linux equivalent, so keep a Windows or Mac machine for that or move to iCloud
backups over wifi. Second, music files you bought from the iTunes Store years ago and never
redownloaded live in your iTunes Media folder on the old computer, so copy that folder across
before you wipe Windows.
Once copied, those files play fine. Anything bought since 2009 has no copy protection on it.
Strawberry and Rhythmbox both read the folder structure, though neither imports your iTunes
playlists automatically, so export the playlists you care about while you still can.
