我在Ubuntu 18.04上执行命令'sudo apt update'，并出现相同的错误。 使用这些实验性软件包，滚动发布版本可能仍然会失败，因为它取决于计算机的当前配置。
转到：“软件和更新”>“其他软件”，并禁用添加到列表ppa存储库的符号。
然后运行以下命令并重新启动计算机：
sudo rm -vf /var/lib/apt/lists/*
sudo apt clean
sudo apt update ; reboot

对于可能仍然会遇到相同问题的任何人，上述解决方案均不适用于我。就我而言，根目录分区已满（已用完100％），我用
df -h
cd /
du -sch * --exclude=home
检查正在使用什么磁盘空间。就我而言，在根目录中有一个mysql数据文件夹的备份，占了9.1GB空间的约3.7GB。 我所做的就是删除mysql文件夹。但是请注意删除的内容。
