誤って削除したcppといくつかの重要なソフトウェア
最新バージョンのgcc（gcc-7）をインストールしようとしました。コマンドを実行すると
Sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-7 60 --slave /usr/bin/g++ g++ /usr/bin/g++-7
これは私がしました：-
$ Sudo update-alternatives --install "/usr/bin/cpp" "cpp" "/usr/bin/cpp-7" 1
update-alternatives: renaming cpp link from /lib/cpp to /usr/bin/cpp
$ Sudo update-alternatives --config cppupdate-alternatives: error: cannot stat file '/usr/bin/cpp': Too many levels of symbolic links
だから私はCPPをrevmoev

pls私は助けが必要です！
https://packages.ubuntu.com/xenial/AMD64/cpp/download からcppをダウンロードし、次のようにインストールしました：-
Sudo dpkg -i cpp_5.3.1-1ubuntu1_AMD64.deb
そして、問題を解決する残りのパッケージをインストールしました
