While there are comparable questions out there, I have not found a solution for this specific circumstance. And I admit that this particular question may be appropriate to only me; however, the question still stands in the general sense. Given a binary only, how do you determine which libraries it needs to run? The commands below are executing on:
chrisheady@linux:~/Dropbox$ uname -a
Linux linux 4.15.0-43-generic #46-Ubuntu SMP Thu Dec 6 14:45:28 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
The file in question is "lmgrd." When I try to run the executable this is what I get:
chrisheady@linux:~/Dropbox$ ./lmgrd
bash: ./lmgrd: No such file or directory
I have tried to debug using a few easy Linux commands, such as:
chrisheady@linux:~/Dropbox$ ls -la lmgrd
-rwxrwxrwx 1 chrisheady chrisheady 1562496 Mar 1 2018 lmgrd
chrisheady@linux:~/Dropbox$ file lmgrd

I attempted ln -s /lib64/ld-linux-x86-64.so.2 /lib64/ld-lsb-x86-64.so.3 followed by ldconfig -n /lib64 but when I execute lmgrd, I still get the same error.
~/Dropbox- are you actually working in a Dropbox folder? if so I wonder if the issue might not be related to library linkage at all?ldd lmgrd, which you suggested in your question, answers the question you've asked.lddlists the libraries required to run the application.ldconfig. But you do realise you've linked two different libraries together, don't you (ld-linuxvsld-lsb).ldconfig -n /lib64then tryinglmgrdagain, fails with the same error.
