Dropbox is planning to drop support for lots of filesystems. Dropbox shows me notifications saying my filesystem is unsupported, but doesn't tell me what it thinks my filesystem is. I believe it's unencrypted ext4, which Dropbox supports, but apparently Dropbox thinks it's different.
Here are the relevant entries from running
/home/user/.dropboxloopback on /home/user/Dropbox type ext4 (rw,nosuid,nodev,noexec,relatime,data=ordered,user=user) /home/.ecryptfs/user/.Private on /home/user type ecryptfs (rw,nosuid,nodev,relatime,ecryptfs_fnek_sig=REDACTED,ecryptfs_sig=REDACTED,ecryptfs_cipher=aes,ecryptfs_key_bytes=16,ecryptfs_unlink_sigs)
My Dropbox folder is
/home/user/Dropbox. How can I find out what Dropbox thinks its filesystem is and investigate this further?
Apart from Android devices, I have only one device connected to my account.
(Aside: I'm using this approach.)
