gpg prompts for passphrase after upgrade to SLES 15 which includes gpg2 package 2.2.5
This document (000020595) is provided subject to the disclaimer at the end of this document.
gpg --yes --batch --passphrase "xxxxx" --output unencrypt.txt --decrypt source.txt.asc
However, after upgrade to SLES 15 which includes gpg2 package version 2.2.5-x, the above command still prompts for a passphrase (if one is not already held in cache).
gpg --yes --pinentry-mode loopback --passphrase "xxxxx" --output unencrypt.txt --decrypt source.txt.asc
--passphrase option, the following statement is now present:
"Since Version 2.1 the --pinentry-mode also needs to be set to loopback."
One confirmed way to do this:
In the home directory of the user who will be executing gpg, edit (or create) the file:
Within that file, set the option: default-cache-ttl 0
Save that. Then find the gpg-agent for that user with:
ps aux | grep gpg-agent | grep <username>
sles15sp2:~ # ps aux | grep gpg-agent | grep root
root 8748 0.0 0.1 166368 1292 ? Ss 17:38 0:00 gpg-agent --homedir /root/.gnupg --use-standard-socket --daemon
root 8819 100 0.0 7424 860 pts/1 S+ 17:49 0:00 grep --color=auto gpg-agent
In the above example, the PID of the agent is 8748.
Kill the process with it's PID. In this example, the command would be:
Then make new attempts at using gpg from the command line. This should automatically cause gpg-agent to launch again, and will now use the new cache time (0 = no cache). With the cache off, testing gpg and interpreting the results should be more reliable.
