私は Linux ベースの OS は初めてです (そして Snap7 も初めてです)。http://python-snap7.readthedocs.io/en/latest/installation.htmlの指示に従って、Ubuntu マシンに Snap7 ライブラリをインストールしようとしています。ただし、3番目のステップで次のエラーが発生します

E: Unable to locate package libsnap71
E: Unable to locate package libsnap7-dev

手動でインストールする方法が正確にわからず、このインストールの問題を修正する方法がわからないので、素晴らしいアドバイスがあれば:)

以下は、「リポジトリの追加」コマンドを実行した後のログのコピーです。

If you are using Ubuntu you can use the Ubuntu packages from our launchpad PPA.
To install:

$ sudo add-apt-repository ppa:gijzelaar/snap7
$ sudo apt-get update
$ sudo apt-get install libsnap71 libsnap7-dev

3 つのコマンドをすべて順番に実行すれば問題ありません。ただし、ソフトウェアはシステムよりも古いため、最初の手順の後に作成されたファイルを編集/etc/apt/sources.dし、. ppa には、古いリリース用のビルドしかありません。xenialyakettytrusty
