sudo apt --fix-broken install時のエラー

apt upgrade実行時にエラーでハマったときのメモ。

問題

$ sudo apt upgrade
Reading package lists... Done

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 libhdf5-openmpi-dev : Depends: libopenmpi-dev but it is not installed
 mpi-default-bin : Depends: openmpi-bin but it is not installed
 mpi-default-dev : Depends: libopenmpi-dev but it is not installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

言われたとおりapt --fix-broken installを実行してみる。

解決策

上記のエラーの最後に書いてある.debファイルをエラーを強制的に無視してインストール。

$ sudo dpkg --force-all -i /var/cache/apt/archives/libopenmpi-dev_2.1.1-8_amd64.deb
$ sudo dpkg --force-all -i /var/cache/apt/archives/openmpi-bin_2.1.1-8_amd64.deb
