GPT PMBR size mismatch

GPT PMBR size mismatch (41943039 != 262143999) will be corrected by write.
The backup GPT table is not on the end of the device. This problem will be corrected by write

While doing fdisk on server was getting the error mentioned above

The solution to this issue was to use command parted -l

[root@db ~]# parted -l
Warning: Not all of the space available to /dev/vda appears to be used, you can
fix the GPT to use all of the space (an extra 220200960 blocks) or continue with
the current setting?
Fix/Ignore? fix

The issue was due to Almalinux updated their GPG keys recently, and it appears the server may not have had the most up-to-date version.

Running command fixed the issue

rpm –import https://repo.almalinux.org/almalinux/RPM-GPG-KEY-AlmaLinux

Now cpanel install is working fine
