Windows Bash (WSL) - sudo: no tty present and no askpass program specified
提问by Chris Rogers
After following this tutroialI get the following error when trying to run the commands as user or even sudo:
遵循此教程后，尝试以用户甚至 sudo 身份运行命令时出现以下错误：
sudo: no tty present and no askpass program specified
sudo：不存在 tty 且未指定 askpass 程序
The comments from Lurdanin this article state that you need to run
Lurdan在本文中的评论指出您需要运行
sudo -S <YOUR_COMMAND>
chmod 0666 /dev/tty
chmoddoesn't work but sudo -Sdoes, but surely there's another fix?
chmod不起作用但sudo -S确实如此，但肯定还有其他解决方法吗？

So silly, after looking further down I see a solution from Beorat:
太傻了，再往下看后，我看到了Beorat的解决方案：
To avoid the sudo tty issue and others, run these commands just before running do-release-upgrade:
为避免 sudo tty 问题和其他问题，请在运行 do-release-upgrade 之前运行这些命令：
sudo -S apt-mark hold sudo
sudo -S apt-mark hold procps
sudo -S apt-mark hold strace
If you've already upgraded, run the above commands, then manually downgrade to the Trusty packages:
如果您已经升级，请运行上述命令，然后手动降级到 Trusty 软件包：
sudo -S wget http://mirrors.kernel.org/ubuntu/pool/main/s/sudo/sudo_1.8.9p5-1ubuntu1.1_amd64.deb
sudo -S wget http://mirrors.kernel.org/ubuntu/pool/main/p/procps/procps_3.3.9-1ubuntu2_amd64.deb
sudo -S wget http://mirrors.kernel.org/ubuntu/pool/main/s/strace/strace_4.8-1ubuntu5_amd64.deb
sudo -S dpkg -i sudo_1.8.9p5-1ubuntu1.1_amd64.deb
sudo -S dpkg -i procps_3.3.9-1ubuntu2_amd64.deb
sudo -S dpkg -i strace_4.8-1ubuntu5_amd64.deb

WSL uses the lxrun executable for management from Windows:
WSL 使用 lxrun 可执行文件从 Windows 进行管理：
lxrun -h
lxrun -h
Usage:
/install - Installs the subsystem
Optional arguments:
/y - Do not prompt user to accept
/uninstall - Uninstalls the subsystem
Optional arguments:
/full - Perform a full uninstall
/y - Do not prompt user to accept
/setdefaultuser - Configures the subsystem user that bash will be launched as. If the user does not exist it will be created.
Optional arguments:
username - Supply the username
/y - If username is supplied, do not prompt to create a password
/update - Updates the subsystem's package index
Given that, you can use lxrun /setdefaultuser root. Just thought I'd point out this side of it since it was required when I ran into the same issue as you after trying to upgrade to Xenial. I can confirm that running this command, then the wget / dpkg commands my issues were resolved.
鉴于此，您可以使用lxrun /setdefaultuser root. 只是想我会指出它的这一方面，因为当我在尝试升级到 Xenial 后遇到与您相同的问题时需要它。我可以确认运行此命令，然后 wget / dpkg 命令我的问题已解决。
The commands I used:
我使用的命令：
wget http://mirrors.kernel.org/ubuntu/pool/main/s/sudo/sudo_1.8.9p5-1ubuntu1.4_amd64.deb
wget http://mirrors.kernel.org/ubuntu/pool/main/p/procps/procps_3.3.9-1ubuntu2_amd64.deb
wget http://mirrors.kernel.org/ubuntu/pool/main/s/strace/strace_4.8-1ubuntu5_amd64.deb
dpkg -i sudo_1.8.9p5-1ubuntu1.4_amd64.deb
dpkg -i procps_3.3.9-1ubuntu2_amd64.deb
dpkg -i strace_4.8-1ubuntu5_amd64.deb
Finally, you might need to run sudo apt-get install -fin case you get The following packages have unmet dependencies [xxx] but it is not going to be installed
最后，您可能需要运行sudo apt-get install -f以防万一The following packages have unmet dependencies [xxx] but it is not going to be installed

I got rid of the error by moving /etc/hosts to /etc/hosts.bu. After closing the shell en opening again, /etc/hosts is recreated and your computer name is added. The error is gone (for me.)
我通过将 /etc/hosts 移动到 /etc/hosts.bu 来消除错误。关闭 shell 再次打开后，会重新创建 /etc/hosts 并添加您的计算机名称。错误消失了（对我来说。）
