我正在尝试从here在Linux的Windows子系统上安装sbt。以下是我的bash终端输出：
username:repo$ echo "deb https://dl.bintray.com/sbt/debian /" | sudo tee -a /etc/apt/sources.list.d/sbt.list
deb https://dl.bintray.com/sbt/debian /
username:repo$ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 2EE0EA64E40A89B84B2DF73499E82A75642AC823

gpg: connecting dirmngr at '/tmp/apt-key-gpghome.NbSR0JqpKB/S.dirmngr' failed: IPC connect call failed
gpg: keyserver receive failed: No dirmngr
我检查了是否已安装
dirmngr。 sudo apt-get update提供以下输出：Hit:1 http://archive.ubuntu.com/ubuntu bionic InRelease

我已经看过this similar question about installing
crystal，但是不知道如何将解决方案应用于这种情况。 最佳答案
这是WSL错误，请参见此workaround。
您只需要更改十六进制值。因此，对于SBT，它将是：
curl -sL "http://keyserver.ubuntu.com/pks/lookup?op=get&search=0x2EE0EA64E40A89B84B2DF73499E82A75642AC823" | sudo apt-key add
PS：请注意此命令旨在替代以下命令
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 2EE0EA64E40A89B84B2DF73499E82A75642AC823
如您所见，两个十六进制值都相同。 （除了在第一个中，您在
0x前面添加了，用于表示以下是十进制值）。因此，此解决方法可以应用于任何密钥。
