カーネルモジュールの署名後のパッケージエラー

修正する

パッケージをアップグレードまたはインストールしようとするたびに、次のエラーが発生します。

 libc6-dbg : Depends: libc6 (= 2.31-0ubuntu9.1) but 2.31-0ubuntu9 is to be installed
 libc6-dev : Depends: libc6 (= 2.31-0ubuntu9.1) but 2.31-0ubuntu9 is to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

-fを使用してアップグレードしようとすると、次のエラーが発生します。

Errors were encountered while processing:
 /var/cache/apt/archives/libc6_2.31-0ubuntu9.1_amd64.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

-f がないと別のエラーが発生します。

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 libc6-dbg : Depends: libc6 (= 2.31-0ubuntu9.1) but 2.31-0ubuntu9 is installed
 libc6-dev : Depends: libc6 (= 2.31-0ubuntu9.1) but 2.31-0ubuntu9 is installed

**END UPDATE**

I

Ubuntu 20.04.1 LTSの実行とVirtualboxバージョン6.1.14 r140239（Qt5.12.8）のインストール

仮想マシンを作成しようとしていますが、次のエラーが発生します。

Kernel driver not installed (rc=-1908)

The VirtualBox Linux kernel driver is either not loaded or not set up correctly. Please try setting it up again by executing

'/sbin/vboxconfig'

as root.

If your system has EFI Secure Boot enabled you may also need to sign the kernel modules (vboxdrv, vboxnetflt, vboxnetadp, vboxpci) before you can load them. Please see your Linux system's documentation for more information.

where: suplibOsInit what: 3 VERR_VM_DRIVER_NOT_INSTALLED (-1908) - The support driver is not installed. On linux, open returned ENOENT. 

だから私も従うこれスレッドはカーネルモジュールに署名しようとします。

キーが生成されましたが、モジュールに署名できません。 （具体的なエラーは覚えていません）

ただし、パッケージにいくつかのエラーが発生したため、解決できません。
