It seems that for some reason lsb_release -rs is returning 8.2.2004 when it should be 8. I installed lsb_release using dnf -y install redhat-lsb-core, if that should matter.

Same goes for Debian Stretch, it tries to download https://dl.packager.io/srv/pghero/dexter/master/installer/debian/9.13.repo

Hey @denizdogan, thanks for reporting! Can you try replacing $(lsb_release -rs) with $(. /etc/os-release && echo $VERSION_ID)? If that works, will update the instructions.

@ankane It seems to work for Debian! It's hard for me to try for CentOS now that I've switched my solution to be Debian-based. :)

Great, thanks for confirming. It worked in the CentOS Docker image, so think it's safe to update.
