dnf update  --allowerasing just removes package

Here are commands I run:

[root@rhel8-7737 bin]# rpm -q python3-ldb-devel
python3-ldb-devel-1.4.2-2.el8.x86_64


[root@rhel8-7737 bin]# dnf list --showduplicates python3-ldb-devel

Complete!


[root@rhel8-7737 bin]# rpm -q python3-ldb-devel
package python3-ldb-devel is not installed


I asked DNF to update the package. DNF just removed the current, without updating to the newest.

[root@rhel8-7737 bin]# dnf install python3-ldb-devel-1.5.4-1.el8.x86_64
Last metadata expiration check: 0:17:59 ago on Tue 07 May 2019 10:21:28 AM EDT.
Error: 
 Problem: problem with installed package python-ldb-devel-common-1.4.2-2.el8.x86_64
  - package python3-ldb-devel-1.5.4-1.el8.x86_64 conflicts with python-ldb-devel-common(x86-64) < 1.5.4-1.el8 provided by python-ldb-devel-common-1.4.2-2.el8.x86_64
  - conflicting requests
(try to add '--allowerasing' to command line to replace conflicting packages or '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)


Anyway, DNF should not just remove package for `dnf update` command.
