cPanel ELevate Fails On Stage Four libbrotlidec.so.1 Not Found Print

The cPanel ELevate process has been started, and upon reaching stage four, it fails and displays an error about dnf stating the following:

Traceback (most recent call last):
  File "/usr/lib64/python3.6/site-packages/libdnf/error.py", line 14, in swig_import_helper
    return importlib.import_module(mname)

During handling of the above exception, another exception occurred:

The error can be caused when the dnf process inadvertently ends, such as when rebooting your server, which you should never do during the elevation process. You can confirm brotli has not been installed by checking for the missing file:

stat /lib64/libbrotlidec.so.1.0.6
stat: cannot statx '/lib64/libbrotlidec.so.1.0.6': No such file or directory

If this is the case, you can manually install the brotli package by running:

wget http://mirror.centos.org/centos/8-stream/BaseOS/x86_64/os/Packages/brotli-1.0.6-3.el8.x86_64.rpm
rpm -Uvh --force --nodeps brotli-1.0.6-3.el8.x86_64.rpm

After the package has been installed you can continue the cPanel ELevate process by running:

/scripts/elevate-cpanel --continue
