Hi everyone,

I’m running CyberPanel on Ubuntu 22 and recently started getting a 503 Error when accessing the panel.

The error logs show that the WSGI child process is constantly crashing right after it starts:

csharp

CopyEdit

[INFO] Process with PID: xxxx is dead

In /home/cyberpanel/error-logs.txt I’m also seeing this repeated error:

csharp

CopyEdit

invalid literal for int() with base 10: b'0a' [executioner]

I suspect there’s a bug or corruption in the Python environment or CyberPanel itself.

I tried to run a repair/upgrade, but all official scripts seem to return 404 Not Found, for example:

  • https://cyberpanel.net/CyberPanelUpgradeScript.sh
  • GitHub links like https://raw.githubusercontent.com/usmannasir/cyberpanel/...

:red_question_mark: Is there a working upgrade or repair script available?
:red_question_mark: Or a way to fix this crash without reinstalling CyberPanel from scratch?

Thanks in advance for any help!

Try this

sh <(curl https://raw.githubusercontent.com/usmannasir/cyberpanel/stable/preUpgrade.sh || wget -O - https://raw.githubusercontent.com/usmannasir/cyberpanel/stable/preUpgrade.sh)

Sometimes, errors occur due to missing or removed packages unintentionally. A simple update can usually resolve this.
