How-To Reproduce

• install 2.6.1.0.gcfe0d1a55-1
• run script VER=2.6 curl -L https://tarantool.io/cshMMp/release/2.4/installer.sh | bash was run.

Possible solution:

-o Dpkg::Options::=--force-confdef -o Dpkg::Options::=--force-confnew (from https://unix.stackexchange.com/questions/22820/how-to-make-apt-get-accept-new-config-files-in-an-unattended-install-of-debian-f)

Maybe export DEBIAN_FRONTEND=noninteractive will help.

Thanks, Alexander!

Jepsen sets DEBIAN_FRONTEND=noninteractive by default in function that installs packages on Debian (our source code uses these helpers). jepsen.tarantool installs Tarantool itself using in two ways: self building and using tarantool.io/installer.sh. Although I didn't see problem described in issue for a long time I think it is worth to set DEBIAN_FRONTEND for installer.sh too.
