The requirement for tty ownership for commands where pinentry is
required causes problems for shells opened with sudo or su, where
such commands generally result in a "permission denied" kind of error:
$ gpg -d /tmp/encrypted.asc
gpg: public key decryption failed: Permission denied
I can use "script" to work around this but it is a bit of a hack that
relies on the fact that "script" creates a new tty owned by the current
user:
$ script -q -c 'gpg -d /tmp/encrypted.asc'
Is there a correct way to make gpg play nicely inside su/sudo ?
PS I am using su/sudo to change to another unprivileged user, not root.
Thanks,
John
