kali apt update问题

这两天使用卡里进行升级sudo apt update,错误无法升级。

人都傻了，先是换源，换了国内的各种源都没用，都是File has unexpected size，然后我直接重装系统，重装了好多次都是一样的问题。折腾两天，参考下面链接，后问题解决。Kali Network Repositories (/etc/apt/sources.list) | Kali Linux Documentation

echo "deb http://http.kali.org/kali kali-last-snapshot main contrib non-free" | sudo tee /etc/apt/sources.list

就是将kali-rolling分支修改为kali-last-snapshot分支，将/etc/apt/sources.list源更换为kali-last-snaps源，问题解决，可以更新，自己记录一下。
