Prerequisites
Verify Current Installation

Downgrade Procedure
Step 1: Stop Plex Service
sudo systemctl stop plexmediaserver
Step 2: Download Target Version
Download the specific 1.41.6 release package:
wget https://artifacts.plex.tv/plex-media-server-stable/1.41.6.9685-d301f511a/debian/plexmediaserver_1.41.6.9685-d301f511a_amd64.deb
Note: This download link was sourced from the Plex community forums thread addressing core component errors.
Step 3: Install Downgraded Version
Use dpkg to install the older version:
sudo dpkg -i plexmediaserver_1.41.6.9685-d301f511a_amd64.deb
Expected output should show:
dpkg: warning: downgrading plexmediaserver from 1.42.1.10054-f333bdaa8 to 1.41.6.9685-d301f511a
...
PlexMediaServer install: PlexMediaServer-1.41.6.9685-d301f511a - Installation successful.
Step 4: Start Plex Service
Restart the Plex service with the downgraded version:
sudo systemctl start plexmediaserver
Verification
Check Service Status
Verify the service is running correctly:
sudo systemctl status plexmediaserver
Look for:
- ✅ Active: active (running)
- ✅ Version string showing 1.41.6.9685-d301f511a
- ✅ Multiple plugin processes loaded successfully
Verify Version
Confirm the downgrade was successful:
# Check service output for version string
sudo systemctl status plexmediaserver | grep "server-version"
Should show: --server-version 1.41.6.9685-d301f511a
Test Web Interface
Access your Plex web interface to confirm functionality:
http://your-server-ip:32400/web
Prevention (Optional)
Hold Package Version
To prevent automatic updates back to the problematic version:
sudo apt-mark hold plexmediaserver
Remove Hold (When Ready to Update)
When you want to allow updates again:
sudo apt-mark unhold plexmediaserver
Troubleshooting
If Service Fails to Start
- Check system logs:
sudo journalctl -u plexmediaserver -f
- Verify file permissions:
sudo chown -R plex:plex /var/lib/plexmediaserver/

If the artifacts.plex.tv download fails:
- Check community forums for alternative download links
- Verify the exact version string needed for your situation
- Ensure wget/curl can access external HTTPS URLs
