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

Answer 1

dpkg似乎有问题。如果dpkg有执行位，你可以尝试探索：

ls -l /usr/bin/dpkg

必须是这样的：

-rwxr-xr-x 1 root root 249328 2011-10-06 10:04 /usr/bin/dpkg

如果没有此权限，请尝试：

chmod 655 /usr/bin/dpkg

如果dpkg没有丢失的库，你可以看到。试试这个命令：

ldd /usr/bin/dpkg

你必须看到这样的想法：

ldd /usr/bin/dpkg
    linux-vdso.so.1 =>  (0x00007fff179ff000)
    libselinux.so.1 => /lib/x86_64-linux-gnu/libselinux.so.1 (0x00007ff8f8439000)
    libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007ff8f809a000)
    libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007ff8f7e95000)
    /lib64/ld-linux-x86-64.so.2 (0x00007ff8f8671000)

如果你有另一个相同的系统，你可以尝试从这个好的系统中复制/ usr / bin / dpkg ......

或者您可以尝试检查，如果您在文件系统上有dpkg * .deb，请尝试以下操作：

cp /var/cache/apt/archives/dpkg*deb /tmp
cd /tmp
ar x dpkg*deb data.tar.gz
tar xzf data.tar.gz
cp ./usr/bin/dpkg /usr/bin/

如果您没有dpkg * deb文件ind / var / cache / apt / archives，则需要从存储库中获取它...
