Error in transactional-update dup

On MicroOS, when I run sudo transactional-update dup, I get this error at the beginning:

Subprocess failed. Error: Failed to import public key [45A1D0671ABD1AFB-66d76fb0] [PackMan Project (signing key) <packman@links2linux.de>] [expires: 2026-09-03]
History:
 - Command exited with status 1.
 - error: /var/tmp/zypp.ytqhGd/pubkey-45A1D0671ABD1AFB-OVyMph: key 1 import failed.
 - error: can't create transaction lock on /usr/lib/sysimage/rpm/.rpm.lock (Read-only file system)

Why does it happen? How can I avoid or fix it?

@alexzak You need to run interactively to accept the new key… transactional-update -i dup

I see. I didn’t realize that it required interactive input.

@alexzak It does at times, for the likes of new keys, some package conflict etc…
