An error occurs during installation and the package is NOT INSTALLED.
Please tell me how to solve this problem and install the package from the repository NORMALLY!!!

An attempt was also made to install the package using RUN. The package is not installed.
I provide the server console below:

[root@srv03 ejabberd]# sudo ./ejabberd-24.12-1-linux-x64.run
Verifying archive integrity...  100%   MD5 checksums are OK. All good.
