Docker 安裝錯誤：找不到 Pop/groovy 的分發模板

我正在嘗試在我的 Pop_OS 上安裝 Docker！

gustavoeklund in ~ ❯ lsb_release -a
No LSB modules are available.
Distributor ID: Pop
Description:    Pop!_OS 20.10
Release:    20.10
Codename:   groovy

當我執行以下命令時：

gustavoeklund in ~ ❯ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).
OK
gustavoeklund in ~ ❯ sudo add-apt-repository \
  "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
  $(lsb_release -cs) \
  stable"

我收到以下錯誤：

Traceback (most recent call last):
 File "/usr/bin/add-apt-repository", line 330, in <module>
   addaptrepo = AddAptRepository()
 File "/usr/bin/add-apt-repository", line 35, in __init__
   self.distro.get_sources(self.sourceslist)
 File "/usr/lib/python3/dist-packages/aptsources/distro.py", line 91, in get_sources
   raise NoDistroTemplateException(
aptsources.distro.NoDistroTemplateException: Error: could not find a distribution template for Pop/groovy

手動添加源（不帶add-apt-repository）：

echo "deb [arch=amd64] https://download.docker.com/linux/ubuntu groovy stable" |sudo tee /etc/apt/sources.list.d/docker-ce.list
sudo apt update
sudo apt install docker-ce
