@Tutanota will tutadrive sync with my linux/kubuntu system ? I'm using filen.io now as google drive nor proton drive sync with linux - also google drive isn't encrypted so yeah - and i use a self-hosted nextcloud instance which also syncs with my PC

criteria : e2e encryption, sync with linux

google : bad & bad
proton : good & bad
filen.io : good & good

nextcloud is self-hosted and can support e2e encryption - so that's just good I suppose - good & good & good ?
