这格伦贝尔 PPA没有显示任何 bionic 软件包。当您查看此 ppa 的启动板页面时,在“已发布软件包概述”下有一个过滤器,您可以在其中选择 Ubuntu 版本,但 bionic 并未列出。
您可以通过运行以下命令来删除此 ppa:
sudo rm /etc/apt/sources.list.d/grumbel*
另外,我不知道您如何安装 qgis.org 存储库,因此您必须执行以下操作之一。
首先,如果您有此存储库的文件/etc/apt/sources.list.d
,请编辑该文件并将“ubuntu”更改为“debian”,保存该文件然后运行:sudo apt update
。
但是,如果您编辑了/etc/apt/sources.list
文件以添加此存储库,请编辑此文件并在 qgis.org 存储库行上,将“ubuntu”更改为“debian”。然后运行:sudo apt update
或者,您可以删除软件和更新中的有问题的 ppa。
