apt-get update Ubuntu 20.04 VM with Multipass 时哈希和不匹配
Hash sum mismatch when apt-get update Ubuntu 20.04 VM with Multipass
我的问题如下：
我启动了一个新的多通道 VM，它是 Ubuntu 20.04 版本（我没有指定它，只是启动）。
我的新 VM 中的第一个命令是：
sudo apt-get update
我已经有一些错误：
Err:6 http://security.ubuntu.com/ubuntu focal-security/main amd64 Packages

我尝试了一些我在网上找到的解决方案，但 none 有效。
解决方案 1：
sudo rm -rf /var/lib/apt/lists/*
sudo apt-get update -o Acquire::CompressionTypes::Order::=gz
sudo apt-get update && sudo apt-get upgrade
解决方案 2
sudo rm -rvf /var/lib/apt/lists/*
echo "APT::Cache-Limit "100000000";" >> /etc/apt/apt.conf.d/70debconf
解决方案 3
sudo rm -rvf /var/lib/apt/lists/*
&& sudo mv /var/lib/dpkg/status /var/lib/dpkg/status-bad
&& sudo cp /var/lib/dpkg/status-old /var/lib/dpkg/status
&& sudo apt-get update
解决方案 4
sudo apt-get autoclean && sudo apt-get autoremove -y && sudo apt-get update
解决方案 5
sudo rm -rf /var/lib/apt/lists
sudo apt-get clean
sudo apt-get update
我还尝试添加 Ubuntu 密钥服务器：
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 16126D3A3E5C1192
这是我的 source.list

如有任何建议，我将不胜感激！

ps：在我的 WSL2 上一切正常。
在我遇到同样问题的情况下，以下解决方案有效：
sudo su -
mkdir /etc/gcrypt
echo all >> /etc/gcrypt/hwf.deny
apt-get update
我的环境
Windows10.0.19041.508
流浪者 2.2.10
VirtualBox 6.1.14r140239
ubuntu/focal64 Vagrant Box
我在这里找到了答案和解释：
askubuntu.com/questions/1235914/hash-sum-mismatch-error-due-to-identical-sha1-and-md5-but-different-sha256
我尝试在 VM 中安装 Docker (get-docker.sh) 并得到非常相似的错误：“Failed to fetch https://download.docker.com ...哈希和不匹配”。所以我认为这类问题与虚拟机无关，而是与 Windows 10 主机有关。
我将 Hyper-V 启动类型更改为 off 并重新启动了系统：
bcdedit /set hypervisorlaunchtype off
我不太明白为什么，但两个问题都消失了。
这对我有用：
我去了系统更新程序并将 update from local server 更改为 update from main server，然后我 运行 sudo apt update 并且成功了。我希望它也适合你
这对我有用：
sudo apt-get clean
sudo rm -r /var/lib/apt/lists/*
我的问题如下：
我启动了一个新的多通道 VM，它是 Ubuntu 20.04 版本（我没有指定它，只是启动）。 我的新 VM 中的第一个命令是：
sudo apt-get update
我已经有一些错误：

我尝试了一些我在网上找到的解决方案，但 none 有效。
解决方案 1：
sudo rm -rf /var/lib/apt/lists/*
sudo apt-get update -o Acquire::CompressionTypes::Order::=gz
sudo apt-get update && sudo apt-get upgrade
解决方案 2
sudo rm -rvf /var/lib/apt/lists/*
echo "APT::Cache-Limit "100000000";" >> /etc/apt/apt.conf.d/70debconf
解决方案 3
sudo rm -rvf /var/lib/apt/lists/*
&& sudo mv /var/lib/dpkg/status /var/lib/dpkg/status-bad
&& sudo cp /var/lib/dpkg/status-old /var/lib/dpkg/status
&& sudo apt-get update
解决方案 4
sudo apt-get autoclean && sudo apt-get autoremove -y && sudo apt-get update
解决方案 5
sudo rm -rf /var/lib/apt/lists
sudo apt-get clean
sudo apt-get update
我还尝试添加 Ubuntu 密钥服务器：
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 16126D3A3E5C1192
这是我的 source.list

如有任何建议，我将不胜感激！ 谢谢
ps：在我的 WSL2 上一切正常。
在我遇到同样问题的情况下，以下解决方案有效：
sudo su -
mkdir /etc/gcrypt
echo all >> /etc/gcrypt/hwf.deny
apt-get update
我的环境
Windows10.0.19041.508
流浪者 2.2.10
VirtualBox 6.1.14r140239
ubuntu/focal64 Vagrant Box
我在这里找到了答案和解释：
askubuntu.com/questions/1235914/hash-sum-mismatch-error-due-to-identical-sha1-and-md5-but-different-sha256
我尝试在 VM 中安装 Docker (get-docker.sh) 并得到非常相似的错误：“Failed to fetch https://download.docker.com ...哈希和不匹配”。所以我认为这类问题与虚拟机无关，而是与 Windows 10 主机有关。
我将 Hyper-V 启动类型更改为 off 并重新启动了系统：
bcdedit /set hypervisorlaunchtype off
我不太明白为什么，但两个问题都消失了。
这对我有用：
我去了系统更新程序并将 update from local server 更改为 update from main server，然后我 运行 sudo apt update 并且成功了。我希望它也适合你
这对我有用：
sudo apt-get clean
sudo rm -r /var/lib/apt/lists/*
