Answer 1

我们需要确定安装了哪些plymouth-related包。

$ dpkg -l | grep plymouth
ii  libplymouth4:amd64                    0.9.3-1ubuntu10                    amd64        graphical boot animation and logger - shared libraries
ii  plymouth                              0.9.3-1ubuntu10                    amd64        boot animation, logger and I/O multiplexer
rc  plymouth-theme-ubuntu-mate-logo       18.10.1                            all          graphical boot animation and logger - ubuntu-mate-logo theme
rc  plymouth-theme-ubuntu-mate-text       18.10.1                            all          graphical boot animation and logger - ubuntu-mate-text theme
ii  plymouth-theme-ubuntu-text            0.9.3-1ubuntu10                    amd64        boot animation, logger and I/O multiplexer - ubuntu text theme

然后重新安装：

sudo apt-get install --reinstall $(dpkg -l | grep plymouth | awk '{print $2}')

你看，问题解决了：

$ sudo apt-get install -f
