env: ubuntu 20.04 docker runner
qt ver: 5.15.18
linuxdeploy and linuxdeploy-plugin-qt

I’m packaging an AppImage on a machine with no internet access. When I run the following packaging command, I get an error.

Failed to run plugin: qt (exit code: 6)

When I scrolled up, I found another error message.

terminate called after throwing an instance of 'std::runtime_error'
what(): Failed to run ldd: exited with code 1

This issue is similar to #111 , but there’s no concrete solution. I can’t arbitrarily change the Qt version. I’m using the Qt 5.15 commercial edition, installed via the official installer.
