Gpg encryption in usermin

linuxhus1 · March 25, 2026, 12:47pm

it works, i can now send adn encrypt messages also sign messages, i will try this with a other email to

linuxhus1 · March 25, 2026, 12:55pm

but the signing of a new key takes still long time, i have to stop the process, the wired is i have stoppet the process after 1hour loading screen in usermin mail, and the signing works

edit: signing still not works, i have stopped the loading screen, but send a email and sign them is not working

Try this patch as well:

sudo sed -i.bak '/^sub sign_data$/,/^sub verify_data$/ s|--batch --passphrase-file |--batch --pinentry-mode loopback --passphrase-file |' /usr/share/usermin/gnupg/gnupg-lib.pl

Is there anything useful logged in the /var/usermin/miniserv.error log file?

Are there any errors in the browser console?

linuxhus1 · March 25, 2026, 7:04pm

This is a strange error. Do you get the same error when you switch to the Framed Theme?

linuxhus1 · March 28, 2026, 8:41am

i have changed the theme and have this:

also changed the theme in usermin, i have try to sign a key:

[28/Mar/2026:09:43:03 +0100] [192.] /service-worker.js : File not found

Ilia · March 28, 2026, 9:11am

Let’s focus on the issue. Those error messages are not related.

Does email signing and decryption work for you now?

linuxhus1 · March 28, 2026, 10:48am

when i sign a key with the framed theme i have a white page with the navigation on the left side, when i sign a key in the authentic theme i have a endles red loading, goes from left to right …

can i see in the webgui when a key is signed?

Thanks for the feedback! Please apply another patch:

I cannot reproduce this issue. I suggest waiting until new Webmin and Usermin releases become available in the repositories, then try again.

If the problem persists, please provide a screencast of the entire Usermin page so I can better understand how it’s not working for you.

linuxhus1 · March 30, 2026, 7:40am

i will send a screencast, and will send the link in the ticketpost

Ilia · March 30, 2026, 1:52pm

Thanks, you can do it now. If it’s a real bug, we’ll fix it before the upcoming Usermin release.

linuxhus1 · March 30, 2026, 3:10pm

i have send the screencast on the post for staff only
