I’ve been testing this on a Pi4, with 2 operating systems. RaspberrypiOS 64bit (manually built) and Arch linux using the AUR repository script.
in both cases vaults can be created and unlocked using webdav, but “revealing the vault” in FUSE gives an input/output error.
I have tried with the default unlock path, and also by making an empty folder in home, then specifying the unlock location. no files are shown in the folder when browsing to it manually in a file manager.
Using “ls” on the parent dir, the locked and unlocked folders shows as
drwxr-xr-x 3 pi pi 4096 Feb 3 21:48 asdf
d??? ? ? ? ? ? asdfunlocked
NOTE
I’ve also had FUSE issues with cryptomator-cli on armhf and arm64 ,but they work fine on x64. - Wondering if there is an issue with the fuse adapter working on ARM?
