You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
snapd : Depends: cgroup-lite but it is not going to be installed
Recommends: linux-generic-lts-xenial but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

我怀疑sudo service --status-all可能会列出 snapd 实例。在这种情况下，使用 停止它sudo systemcl stop snapd。要么是这个，要么是你在 dpkg 上设置了锁。您可以使用pgrep -f 'dpkg|apt( 的后继ps afx|grep dpkg) 检查后者，然后删除卡住用 锁sudo rm /var/lib/dpkg/lock。
