5 years ago What is the output of pacman -Ql gdbm | grep libgdbm.so?
I believe the gdbm package is on libgdbm.so.6, which means you will have to recompile the package roscore is under which is ros-melodic-roslaunch (can be found by pacman -Qo /opt/ros/melodic/bin/roscore). This may also mean you might have to reinstall a bunch of ros packages.
Try reinstalling and see where that gets you.
Also if you want to speed up your installation take a look at the official installation guide for ROS Melodic on ArchLinux here: https://wiki.ros.org/melodic/Installation/ArchLinux. You can add a user repository called arch4edu to speed your installation.
Let us know if the reinstallation fixes your issue.
