我刚刚从 21.04 更新到 22.04。
启动后，我多次收到有关更新的请求。我点击“安装”，它开始运行。然后显示“无法安装，请检查互联网连接”。
今天我想起要尝试自己进行更新。
事情是这样的：
me@me-desktop:~$ sudo apt update
[sudo] password for me:
Reading package lists... Done
E: Could not get lock /var/lib/apt/lists/lock. It is held by process 2757 (packagekitd)
N: Be aware that removing the lock file is not a solution and may break your system.
E: Unable to lock directory /var/lib/apt/lists/
me@me-desktop:~$
我该如何解决这个问题？
