I'm following the current crystal installation docs, my installation stops at the first moment and give the error:
gpg: connecting dirmngr at '/tmp/apt-key-gpghome.4GKHZljOFL/S.dirmngr' failed: IPC connect call failed
gpg: keyserver receive failed: No dirmngr
I've already installed dirmngr.
First of all, you need to remove crystal.list from sources directory to install from start manually.
sudo rm /etc/apt/sources.list.d/crystal.list
And then:
curl -s "https://keyserver.ubuntu.com/pks/lookup?op=get&search=0x09617FD37CC06B54" | sudo apt-key add -
echo "deb https://dist.crystal-lang.org/apt crystal main" > /etc/apt/sources.list.d/crystal.list
sudo apt-get update
sudo apt-get install crystal
