Electronic Eel 3ed1aec1bd Do GPG signature checking for the whole migration process

Before this commit, the Rocky system packages like rocky-repos,
rocky-release and similar, were not checked for their gpg signature,
while the rest of the packages were signature checked.
While the system packages were downloaded from https://dl.rockylinux.org,
this still created the risk that someone could attack the CDN infrastructure
behind dl.rockylinux.org and place malicous files there.

With this patch the GPG key is downloaded separately and then compared
against a checksum contained in the script. This adds an extra layer of
security.

Rocky Tools

Various scripts and tools that we find useful, whether we use them or they are made for public consumption. For example, conversion scripts or otherwise.

[migrate2rocky] -- Conversion Script

Running this script will convert an existing CentOS 8 system to Rocky Linux 8.

Usage

./migrate2rocky.sh -h
├── -h   # --> Display this help
├── -r   # --> Convert to Rocky
└── -V   # --> Verify switch

[!! USE WITH CAUTION !!]

Known Issues

RHEL migrations show error messages during conversion

  Installing       : rocky-release-8.3-13.el8.noarch                        2/5Error unpacking rpm package rocky-release-8.3-13.el8.noarch
...
error: unpacking of archive failed on file /usr/share/redhat-release: cpio: File from package already exists as a directory in system
error: rocky-release-8.3-13.el8.noarch: install failed
...
Error: Transaction failed

This results from conflicts in the directory structure of RHEL with that of RockyLinux. migrate2rocky will detect the issue and go on to remove the conflicting directory and install rocky-release with the rpm command.

Grub still shows kernel entries from previous installation

This is normal. The running kernel cannot be safely removed when migrate2rocky is run. The RockyLinux kernel should come up as the default highlighed kernel on reboot but the other ones will remain until they are removed or replaced by newer kernels. If you want you can manually remove the old kernels after reboot with dnf or rpm.

Latest Version

The latest version of this script can be found here.

Debugging

The migrate2rocky script pipes everything shown on stdout and stderr to /var/log/migrate2rocky.log.

If you run in to issues executing this script, please submit an issue here.

Make sure to include the output log, and remove any sensitive information. (if any)

Feel free to create a pull request if you think you've got the fix.
