ubuntu - 无法安装 RStudio，无法安装 'libclang-dev'

Question

我使用 ubuntu 20.04.2。我在使用 rStudio 时遇到了一些问题，所以我完全从我的电脑上卸载了。我已经安装了 r，但现在我想安装 rStudio，但是当我尝试安装时，我发现“libclang-dev”是可卸载的。

$ sudo gdebi rstudio-1.4.1106-amd64.deb

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

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

我设法解决它。我跑sudo aptitude install clang .首先，您需要对您收到的第一个提案说不(“n”)，然后会出现一个新提案。如果您接受(“y”)第二个，则安装一些软件包:

<pre>The following NEW packages will be installed:
  clang clang-10{a} lib32gcc-s1{a} lib32stdc++6{a} libc6-i386{ab} libclang-common-10-dev{a} libclang-cpp10{a} libclang1-10{a} libffi-dev{a} libllvm10{a} libncurses-dev{a} libobjc-9-dev{a} libobjc4{a} 
  libomp-10-dev{a} libomp5-10{a} libpfm4{a} libtinfo-dev{a} libz3-4{a} libz3-dev{a} llvm-10{a} llvm-10-dev{a} llvm-10-runtime{a} llvm-10-tools{a}

The following packages have unmet dependencies:
 libc6-i386 : Depends: libc6 (= 2.31-0ubuntu9.2) but 2.31-0ubuntu9.3 is installed
The following actions will resolve these dependencies:

     Keep the following packages at their current version:
1)     clang [Not Installed]                              
2)     clang-10 [Not Installed]                           
3)     lib32gcc-s1 [Not Installed]                        
4)     lib32stdc++6 [Not Installed]                       
5)     libc6-i386 [Not Installed]                         
6)     libclang-common-10-dev [Not Installed]</pre>
