我试图安装 readline 作为 octave 4.0.0 的依赖项。
然后出现问题apt-get install并提示执行
sudo apt-get -f install.
以下是我收到的内容：
xxxx@xxxx-MS-7577:~$ sudo apt-get -f install

谢谢。如果我运行此命令，我会收到以下内容：
sudo apt-get remove libc6-amd64:i386 libc6-dev-amd64:i386

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
gcc-5-multilib : Depends: libc6-dev-i386 (>= 2.11) but it is not going to be installed
lib32readline6-dev : Depends: libc6-dev-i386 but it is not going to be installed
lib32tinfo-dev : Depends: lib32c-dev
lib64readline6:i386 : Depends: libc6-amd64:i386 (>= 2.15) but it is not going to be installed
lib64readline6-dev:i386 : Depends: libc6-dev-amd64:i386 but it is not going to be installed
lib64tinfo5:i386 : Depends: libc6-amd64:i386 (>= 2.16) but it is not going to be installed
libc6-dev-x32 : Depends: libc6-dev-i386 (= 2.21-0ubuntu4) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
现在的问题是我无法升级系统。我被这个错误锁定了。尝试执行sudo apt-get -f install是无用的，因为我进入了之前的错误状态。
答案1
摆脱libc6-dev-amd64:i386
sudo apt-get remove libc6-amd64:i386 libc6-dev-amd64:i386
它仅用于 32 位（i386）Ubuntu 安装中的 64 位（amd64）交叉编译。
