PackageKit 数据库磁盘映像格式不正确

每次使用 apt 时，我都会收到“超时错误”。查看/var/log/syslog，我看到：

dbus[619]: [system] Activating via systemd: service name='org.freedesktop.PackageKit' unit='packagekit.service'
systemd[1]: Starting PackageKit Daemon...

有人遇到过这个问题吗？有没有什么方法可以修复数据库？或者我只能重新安装 packagekit 吗？

答案1

下列做过工作：

sudo apt-get remove packagekit
sudo apt-get purge packagekit
sudo apt-get install ubuntu-software

或者，您也可以使用以下命令：

sudo apt-get remove --purge packagekit
sudo apt-get install ubuntu-software

我曾希望找到更好的解决方案。我确实找到了带有选项的命令pkcon，repair但依赖于packagekitd正在运行才能与数据库交互。

我在网上找不到任何关于数据库存储位置或如何处理该问题的参考资料。与 PackageKit 相关的大多数问题都与 Fedora、RedHat 或 CentOS 有关，因此帮助不大。

答案2

数据库文件如下。删除它并重新启动 packagekit 服务

/var/lib/PackageKit/transactions.db
