如何修正dpkg错误代码(100)

Question

即使是dpkg，我也无法安装任何软件包，我的dpkg文件和文件夹已经被删除，我收到了以下错误：

Could not exec dpkg!
E: Sub-process /usr/bin/dpkg returned an error code (100)

编辑:当我运行sudo apt-get update && sudo apt-get install --reinstall dpkg时，我得到了以下输出：

dpkg: warning: 'dpkg-deb' not found in PATH or not executable.
dpkg: error: 1 expected program not found in PATH or not executable.
Note: root's PATH should usually contain /usr/local/sbin, /usr/sbin and /sbin.
E: Sub-process /usr/bin/dpkg returned an error code (2)

您可能希望通过执行以下操作重新安装dpkg：

sudo -i
mkdir /tmp/dpkg

cd /tmp/dpkg

请注意，您可能希望查看下载链接是否仍然是最新的。

如果您正在运行ubuntu的32位版本，则为

。wget http://security.ubuntu.com/ubuntu/pool/main/d/dpkg/dpkg_1.17.5ubuntu5.2_i386.deb 64位

wget http://security.ubuntu.com/ubuntu/pool/main/d/dpkg/dpkg_1.17.5ubuntu5.7_amd64.deb

然后

ar x dpkg*.deb data.tar.gz

tar xfvz data.tar.gz ./usr/bin/dpkg

现在将二进制文件复制到/usr/bin中

sudo cp ./usr/bin/dpkg /usr/bin

终于跑了

sudo apt-get update
sudo apt-get install --reinstall dpkg
