在ubuntu 16.04中snapd包管理器问题，如何解决？
After this operation, 33.0 MB disk space will be freed. Do you want to continue? [Y/n] y (Reading database ... 329734 files and directories currently installed.) Removing snapd (2.21~14.04) ...

接下来删除一个包dpkg --purge --force-all snapd 。
检查你的pkg来源是否可靠rgrep 'xenial' /etc/apt ，并删除我所对应的所有来源的inperper版本的snapd。
运行apt-get update ，并将系统升级为一致状态。
