我剛剛在這台機器上安裝了 Linux mint，並且無線連接無法開箱即用。您可以在下面找到更多資訊：

編輯2：我嘗試按照stackoverflow中的這些步驟進行操作。
sudo apt install build-essential git git clone https://github.com/rtlwifi-linux/rtlwifi-next cd rtlwifi-next make sudo make install sudo modprobe rtl8822be但我得到了這個錯誤：
抄送
$$ M $$ /home/MYUSER/Downloads/rtlwifi-next/base.o /home/MYUSER/Downloads/rtlwifi-next/base.c：在函式’_rtl_init_deferred_work’中：/home/MYUSER/Downloads/rtlwifi-next/base.c： 460:2：錯誤：函式“setup_timer”的隱式聲明；你的意思是“sk_stop_timer”嗎？ $$ -Werror=implicit-function-declaration $$
setup_timer(&rtlpriv->works.watchdog_timer, ^~~~~~~~~~~
sk_stop_timer
編輯 3：在我發布答案後，我啟用了安全啟動，我的 wifi 停止工作。因此，我的 wifi 僅在我的安全啟動被禁用時工作。
作為替代答案，您可以使用 MOK 密鑰簽署驅動程序
完整的文章在這裡
這樣您就可以保持啟用安全啟動！
從下載 repo 到完成，編寫這一切的基礎如下所示：
（注意，我簽署了更多的模組，然後我可能需要。我不確定除了 rtl8822be 是我的驅動程序之外的哪些模組，所以為了以防萬一，我在前面沒有 rtl 的情況下簽署了所有模組。）
#Generate a new MOK key sudo update-secureboot-policy --new-key #Enroll key into firmware sudo update-secureboot-policy --enroll-key閱讀註冊密鑰中的說明。 重新啟動電腦並關注他們。
下一部分與之前相同：
sudo apt install build-essential git git clone -b extended https://github.com/lwfinger/rtlwifi_new.git cd rtlwifi_new make有趣的部分來了：
sudo kmodsign sha512 \ /var/lib/shim-signed/mok/MOK.priv \ /var/lib/shim-signed/mok/MOK.der \ rtl_pci.ko sudo kmodsign sha512 \ /var/lib/shim-signed/mok/MOK.priv \ /var/lib/shim-signed/mok/MOK.der \ rtlwifi.ko sudo kmodsign sha512 \ /var/lib/shim-signed/mok/MOK.priv \ /var/lib/shim-signed/mok/MOK.der \ rtl8822be/rtl8822be.ko之後我們以同樣的方式完成
sudo make install sudo modprobe rtl8822be然後瞧，wifi正在工作。
