我尝试使用以下命令卸载 phpmyadmin：
sudo apt-get purge phpmyadmin
但每次都会出现这个错误：
dpkg: error while cleaning up:
subprocess installed post-installation script returned error exit status 127
Errors were encountered while processing:
phpmyadmin
E: Sub-process /usr/bin/dpkg returned an error code (1)
我也尝试了互联网上的其他解决方案，例如：
sudo apt-get --force-yes remove phpmyadmin
仍然出现同样的错误。
谢谢你的回答
