Do you get the same error if you try to decrypt it before moving the file? I tried with the exact same arguments with gpg 2.3.1, libgcrypt 1.9.4 and everything worked well (though I didn't try moving the files to another medium). I also wonder if you're waiting until the file has been fully written (you can ensure this by running `sync` and waiting until it has returned) before trying to decrypt? - Chiraag -- ಚಿರಾಗ್ ನಟರಾಜ್ Pronouns: he/him/his
