障害

aptでsumoをインストールしようとする。すると、こんなエラーメッセージが出てしまう。

$ sudo apt install sumo

しかし、gdal-abi-2-2-3というパッケージはaptに存在していない。さて、どうしようか？

正解: fakeパッケージ

いろいろと方法を試してみた。正解だったのは、fakeパッケージを作成して、真のパッケージへの参照情報を紹介することだった。

次の手順を実行してみる。

vim gdal_abi.txt
sudo apt install equivs
sudo equivs-build gdal_abi.txt 
sudo dpkg -i gdal-abi-2-2-3_2.2.3_all.deb 
sudo dpkg -i gdal_abi.txt
sudo apt install sumo

vim gdal_abi.txt

sudo apt install equivs

sudo equivs-build gdal_abi.txt

sudo dpkg -i gdal-abi-2-2-3_2.2.3_all.deb

sudo dpkg -i gdal_abi.txt

sudo apt install sumo

gdal_abi.txtの中身はこの通り

Section: misc

Standards-Version: 3.9.2
    
Package: gdal-abi-2-2-3
Version: 2.2.3
Depends: libgdal20

SUMOのバージョン確認をしてみる。インストールは成功した様子だ。
