尝试使用sudo apt-get upgrade在Raspberry Pi 2上升级Raspbian（8.0杰西）时，出现以下错误：
dpkg-deb (subprocess): decompressing archive member: lzma error: compressed data is corrupt

有人有什么想法吗？
我已经完成了sudo apt-get update和sudo apt-get clean。

deb 文件本身已损坏。 您可以删除它，然后再次运行更新/升级。它将下载新版本。
像这样：
cd /var/cache/apt/archives
sudo rm perl_5.20.2-3+deb8u12_armhf.deb
sudo apt-get update
sudo apt-get upgrade -y
