'apt install' 无法安装有效的软件包

  • 772

我把 vscode 下载到了下载

me@host:~$ ls Downloads/code_1.31.1-1549938243_amd64.deb 
Downloads/code_1.31.1-1549938243_amd64.deb

用apt安装，提示找不到

me@host:~$ sudo apt install Downloads/code_1.31.1-1549938243_amd64.deb

该软件包状况良好，因为我最终使用 gnome gui 安装了它。

我使用 ap install 有什么问题？

apt

    从man apt，在关于 的段落中install：

    A specific version of a package can be selected for installation by following the
package name with an equals (=) and the version of the package to select.
Alternatively the version from a specific release can be selected by following the
package name with a forward slash (/) and codename (jessie, stretch, sid ...) or suite
name (stable, testing, unstable).

    所以被apt视为Downloads包名，因为它是一个非常好的包名，其余的则作为目标。为了使 apt 将其视为路径，路径必须以不能是包名称的内容开头，例如.or /：

    $ sudo apt install Downloads/bash*.deb
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package Downloads

    领先.：

    $ sudo apt install ./Downloads/bash*.deb
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Note, selecting 'bash' instead of './Downloads/bash_4.4.18-1ubuntu1~16.04.york0_amd64.deb'
bash is already the newest version (4.4.18-1ubuntu1~16.04.york0).
0 to upgrade, 0 to newly install, 0 to remove and 4 not to upgrade.
