尝试通过以下链接安装詹金斯，但最终遇到以下问题
https://www.liquidweb.com/kb/installing-jenkins-on-ubuntu-16-04/
subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
jenkins
E: Sub-process /usr/bin/dpkg returned an error code
再次重新安装dpkg并尝试安装jenkins，但最终遇到相同的问题
Could someone please guide me to resolve this issue?
