I am running openSUSE Leap 42.1 in a Vagrant box and while I had to debug a small executable file, I came across a message prompting me to install the glibc-debuginfo-2.19-19.1.x86_64 package.
(gdb) run Starting program: /home/vagrant/hi Missing separate debuginfos, use: zypper install glibc-debuginfo-2.19-19.1.x86_64
Breakpoint 1, 0x0000000000400561 in main ()
I searched for the package and could not find it in the enabled repositories. It didn’t ring in my head that it’s a ‘debug’ related package and it could be in a repository other than the default repos enabled by YaST during install time. openSUSE has several official repositories that are listed on its wiki page.
I added the ‘debug’ repository. You may include the
-f flag to the zypper command to enable autorefresh, I did not since I prefer refresh manually.

I refreshed the repos and installed the glibc-debuginfo package. However, it installed version 2.19-17.4 while gdb prompted for 2.19-19.1. Running gdb this time continued to prompt the missing glibc-debuginfo package and would complain about checksum errors.

It happens that debug related latest packages are in the ‘debug updates’ repository which was not present, and thus the package manager didn’t find version 2.19-19.1. I added the repository for Leap 42.1 and upgraded the glibc-debuginfo package. Gdb now runs without complaining.
Thanks to Stephan Kulow for the hints.
