The error is caused by a 3rd party kernel module (rtl8723de) and is not a bug with the kernel or Ubuntu: ERROR (dkms apport): binary package for rtl8723de: 5.1.1.8_21285.20171026_COEX20170111-1414 not found Error! Bad return status for module build on kernel: 6.11.0-21-generic (x86_64) The kernel now contains its own module for your wireless adapter, rtw88_8723de, and you shouldn't need an external module. If your wireless is working satisfactorily, then you should remove the rtl88x2bu module.
