"gpg: signing failed: Inappropriate ioctl for device" on MacOS with Maven

Question

I have installed GPG via Homebrew with brew install gpg. It is installed in version 2.2.17.

In my Maven POM I have this snippet:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-gpg-plugin</artifactId>
    <version>1.6</version>
    <executions>
        <execution>
            <id>sign-artifacts</id>
            <phase>verify</phase>
            <goals>
                <goal>sign</goal>
            </goals>
        </execution>
    </executions>
</plugin>

However when running mvn clean verify I get this error:

gpg: Beglaubigung fehlgeschlagen: Inappropriate ioctl for device
gpg: signing failed: Inappropriate ioctl for device

How can I fix this error?

Try running maven with the `-X` argument to find the gpg command line that's actually executed. — JimmyB, Aug 21 '19 at 12:31
@JimmyB Unfortunately there ain't any gpg commands print when using `-X`. — Harold L. Brown, Aug 21 '19 at 12:37

I have added

GPG_TTY=$(tty)
export GPG_TTY

to my ~/.bash_profile file. Now it is working.

This fix worked on my linux machine too. I had gotten the error when piping gpg into ssh. – ki9 Dec 13 '20 at 19:13

or `export GPG_TTY=$(tty)` – Amerousful Jan 26 '21 at 11:50

@Amerousful the given two-line solution is preferred because it doesn't hide the exit code. (Try `export test=$(exit 1); echo $?`) – OJFord Oct 20 '21 at 12:08
Also worked on Ubuntu running in WSL – dcg Aug 04 '23 at 23:21

On macOS you may want to use pinentry-mac to have GUI window to enter pin and optionally store pin in keychain.

You can install it though Homebrew:

brew install pinentry-mac

And enable it with the following line in your ~/.gnupg/gpg-agent.conf config (create it if it doesn't exists):

pinentry-program /usr/local/bin/pinentry-mac

It works once `killall gpg-agent` has been ran after applying your proposal. – meduz' Apr 25 '20 at 23:05

Thanks so much! This is probably the better way, not sure why this doesn't have more upvotes. – Luca Steeb Jun 19 '20 at 06:57
For me the path was `pinentry-program /opt/homebrew/bin/pinentry-mac` – Mahendra Liya Jul 22 '23 at 14:58

Try this

gpg --use-agent --armor --detach-sign --output $(mktemp) pom.xml

GPG stopped working for me randomly. This worked like a charm and I still have no idea why. Its like the agent had to be kicked or something. – Adam Gent Mar 16 '23 at 21:20

For me, this happened because the terminal window wasn't big enough to fit the passphrase TUI. Once I opened a bigger terminal tab and then I rerun the gpg command, I was able to see the passphrase terminal user interface.

If anybody gets this error message when typing gpg commands in bash, try adding --no-tty. That fixed it for me.

This doesn't work, getting this error again and again. I seriously start to feel nobody knows and just toss random solutions around. What to do then? – Eric Buist Jun 02 '23 at 17:22
@EricBuist. A lot of IT is like that. You google for ideas and try stuff until something works. – RedDragonWebDesign Jun 04 '23 at 20:52
