我只是从公司版本的Eclipse切换到库存Ubuntu版本。
sudo apt-get remove eclipse
我发现我公司的 eclipse 仍然安装着。我猜想它安装在了软件包仓库之外，所以我尝试了：
which eclipse
返回
/usr/bin/eclipse
所以我确认了。Eclipse 的快捷方式仍保留在我的应用程序菜单中，但返回“无法启动应用程序”错误。然后我尝试
sudo apt-get install eclipse
返回成功，但是
which eclipse
没有返回任何内容，并且尝试启动 eclipse 时会出现与未安装 eclipse 时相同的“无法启动应用程序”错误。
如何让 ui/包管理器同意是否/在何处安装 eclipse？如果做不到这一点，我如何确定应用程序菜单试图启动什么，以及如何确定包管理器安装了什么？
编辑：
要求更多输出：
locate eclipse | grep bin/
