我应该怎么办？
答案1
从系统中删除软件包后，您需要重新安装它。我尝试过的许多系统中，重新安装解决了错误。因此，请运行以下命令：
sudo apt-get autoremove
sudo dpkg --configure -a
sudo apt-get install -f
sudo apt remove rtl8821ce-dkms
git clone https://github.com/tomaspinho/rtl8821ce
cd rtl8821ce
chmod +x dkms-install.sh
chmod +x dkms-remove.sh
make
sudo make install
sudo ./dkms-install.sh
然后重新启动。

我正在安装 rtl8821ce-dkms_5.5.2.1-0ubuntu6_全部（不是“0ubuntu4_all”）并且有效：
wget http://archive.ubuntu.com/ubuntu/pool/universe/r/rtl8821ce/rtl8821ce-dkms_5.5.2.1-0ubuntu6_all.deb
sudo dpkg -i rtl8821ce-dkms_5.5.2.1-0ubuntu6_all.deb
