OpenSuSE Tumbleweed `zypper dist-upgrade`: `mt-st` versus `mt_st`

TL;DR: I’m not the only one being partially word-blind.

I had the below while performing a zypper distribution upgrade on "openSUSE Tumbleweed (20160726) (x86_64)".

revue:/etc # zypper dist-upgrade
...
Detected 2 file conflicts:

File /usr/bin/mt
  from install of
     mt-st-1.3-1.1.x86_64 (Main Repository (OSS))
  conflicts with file from package
     mt_st-1.3-1.2.x86_64 (@System)

File /usr/sbin/stinit
  from install of
     mt-st-1.3-1.1.x86_64 (Main Repository (OSS))
  conflicts with file from package
     mt_st-1.3-1.2.x86_64 (@System)

File conflicts happen when two packages attempt to install files with the same name but different contents. If you continue, conflicting files will be replaced losing the previous content.
Continue? [yes/no] (no): no

Problem occured during or after installation or removal of packages:
Installation aborted by user

Please see the above error message for a hint.

Did you see the cause of the error in the above message?

Neither did I.

So I went to the #opensuse-factory IRC channel with this information:

There cooloo pointed out both the cause and solution were deceptively simple:

coolo: wiert: zypper remove mt_st ; zypper dup; zypper in mt-st
coolo: the package was incorrectly renamed

My partial word-blindness didn’t spot the difference between mt_st and mt-st, but it was indeed renamed.

So here I went:

zypper remove mt_st ; zypper dist-upgrade; zypper install mt-st

Note that strictly zypper install mt-st isn’t needed on my system as it is part of  Base:System. which means that zypper dist-upgrade automatically re-installed it.
