APT - Невозможно найти пакет (aspnetcore/dotnet runtime, Ubuntu)

Я пытаюсь установить пакет aspnetcore-runtime-3.1, я добавил ключ подписи пакета Microsoft с помощью

wget https://packages.microsoft.com/config/ubuntu/20.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb

Однако sudo apt install aspnetcore-runtime-3.1выдает ошибку:

Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package aspnetcore-runtime-3.1

Поиск пакета с помощью apt search показывает, что пакет существует:

$ sudo apt search aspnetcore

Я попробовал действия по устранению неполадок, перечисленные надокументы Microsoft:

sudo dpkg --purge packages-microsoft-prod && sudo dpkg -i packages-microsoft-prod.deb
sudo apt-get update
sudo apt-get install aspnetcore-runtime-3.1

и

sudo apt-get install -y gpg
wget -O - https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor -o microsoft.asc.gpg
sudo mv microsoft.asc.gpg /etc/apt/trusted.gpg.d/
wget https://packages.microsoft.com/config/ubuntu/20.04/prod.list
sudo mv prod.list /etc/apt/sources.list.d/microsoft-prod.list
sudo chown root:root /etc/apt/trusted.gpg.d/microsoft.asc.gpg
sudo chown root:root /etc/apt/sources.list.d/microsoft-prod.list
sudo apt-get update; \
  sudo apt-get install -y apt-transport-https && \
  sudo apt-get update && \
  sudo apt-get install -y aspnetcore-runtime-3.1

Оба выдают одну и ту же ошибку. Я особенно сбит с толку, поскольку пакет, очевидно, доступен, поскольку отображается в apt search?
