virtualboxゲストの追加：エラー：カーネル構成が無効です
私がしたこと：
- 最小限のdebian/testingをインストール（GUIなし、標準ユーティリティなし）
- build-essential、dkms、linux-headers-$（uname -r）をインストールします
- [デバイス]-> [ゲスト追加CDを挿入]をクリックします
- 実行された

私が得たもの：
...
Building the modules for kernel 5.4.0-4-AMD64.
Look at /var/log/vboxadd-setup.log to find out what went wrong.
modprobe vboxsf failed
...
ログには何があります：
...
test -e include/generated/autoconf.h -a -e include/config
/auto.conf || ( \
echo >&2; \
echo >&2 " ERROR: Kernel configuration is invalid."; \
echo >&2 " include/generated/autoconf.h or include/config/auto.conf are missing.";\
echo >&2 " Run 'make oldconfig && make prepare' on kernel src to fix it."; \
echo >&2 ; \
/bin/false)
...
私が調査したもの：
$modprobe vboxsf
modprobe: FATAL: Module vboxsf not found in directory /lib/modules/5.4.0-4-AMD
$lsmod | grep vboxsf
<no output>
$find /usr/src/linux-headers-5.4.0-4-AMD64/ -name autoconf.h
/usr/src/linux-headers-5.4.0-4-AMD64/include/generated/autoconf.h
ホストOSはUbuntu 18です。
編集：openboxをインストールしてXサーバーを取得すると、ログは次のようになります。

仮想ボックスゲスト追加ドライバーのgcc fallthrough属性に関連するマクロとLinuxカーネルヘッダーの間に競合があるようです。
具体的には、仮想ボックスドライバーは次のようなマクロを定義します。
_root@vdebtest:/usr/src/vboxguest-5.1.38$ grep fallthrough -R
vboxvideo/include/iprt/cdefs.h:# define RT_FALL_THROUGH() __attribute__((fallthrough))
vboxguest/include/iprt/cdefs.h:# define RT_FALL_THROUGH() __attribute__((fallthrough))
vboxsf/include/iprt/cdefs.h:# define RT_FALL_THROUGH() __attribute__((fallthrough))
_しかし include/linux/compiler_attributes.h にあるLinuxカーネルでは、次のようなものがあります。
_/*
* Add the pseudo keyword 'fallthrough' so case statement blocks
* must end with any of these keywords:
* break;
* fallthrough;
* goto <label>;
* return [expression];
*
* gcc: https://gcc.gnu.org/onlinedocs/gcc/Statement-Attributes.html#Statement-Attributes
*/
#if __has_attribute(__fallthrough__)
# define fallthrough __attribute__((__fallthrough__))
#else
# define fallthrough do {} while (0) /* fallthrough */
#endif
_さて、私があなたのビルドログを正しく理解していれば、それらの_RT_FALL_THROUGH_ sは実際には__attribute__((__attribute__((__fallthrough__))))になり、コードをめちゃくちゃにするでしょう。
_/usr/src/vboxguest-x.y.z_ディレクトリに移動して、すべての__attribute__((fallthrough))（これらは私のセットアップでは3つだけです）を__attribute__((__fallthrough__))に置き換えてみてください。 （プレーンfalthroughも機能するはずです）...
次に、それらすべてを_./build_in_tmp_で再構築します。
更新：このトピックについて少し前に不満があったようです here 。そして、これはすでにこれで修正されているようです ticket 。
