无法在 20.04 LTS 上安装 libclang

Question

尝试安装 libclang-dev 后，sudo apt-get install -y libclang-dev我收到此错误：

The following packages have unmet dependencies:
 libclang-dev : Depends: libclang-10-dev (>= 10~) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

当我尝试解决方案时：

 $ wget https://apt.llvm.org/llvm.sh
 $ chmod +x llvm.sh
 $ sudo ./llvm.sh 12

出现这种情况：

The following packages have unmet dependencies:
 clang-12 : Depends: libclang-common-12-dev (= 1:12.0.1~++20210511012537+24535af52ae1-1~exp1~20210510233243.87) but it is not going to be installed
 clangd-12 : Depends: libclang-common-12-dev (= 1:12.0.1~++20210511012537+24535af52ae1-1~exp1~20210510233243.87) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

的输出 sudo apt-cache policy libc6

libc6:
  Installed: 2.31-0ubuntu9.2
  Candidate: 2.31-0ubuntu9.2

您必须使用以下命令将 libc6 库恢复到正常版本：

sudo apt-get install libc6=2.31-0ubuntu9.2 libc6:i386=2.31-0ubuntu9.2
