PackageKit数据库磁盘图像畸形

Question

每次使用apt时，我都会得到“超时到达的错误”。看看/var/log/syslog，我看到了：

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

以前有人遇到过这个问题吗？有办法修复数据库吗？或者我可以重新安装打包包吗？

Answer 1

以下工作取得了成效：

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

另外，您应该能够使用以下选项：

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

我本希望能找到更好的解决办法。我确实找到了带有pkcon选项的repair命令，但是它依赖于运行packagekitd来与数据库交互。

我无法在网上找到任何关于数据库存储位置的引用，也无法找到如何以其他方式处理这个问题的参考。与PackageKit相关的大多数问题都是关于Fedora、RedHat或CentOS的，所以没有那么有帮助。

数据库文件如下所示。删除它并重新启动packagekit服务。

/var/lib/PackageKit/transactions.db
