    @bz87 are you running it as root? That error suggests that you are not.

    set up executable permission using the chmod command, run: chmod -v +x almalinux-deploy.sh
    then try it again

    Thanks ill give it a shot ALSO i just realise when I use command dnf -y update I get this error Error: Failed to download metadata for repo 'appstream': Cannot prepare internal mirrorlist: No URLs in mirrorlist
    @bz87 are you running it as root? That error suggests that you are not.

    please read from AlmaLinux Github page in the link I have above In order to convert your EL8 operating system to AlmaLinux do the following:
    • CentOS 8.4 or 8.5 is required to convert to AlmaLinux. It is recommended to update to 8.5 prior to moving to AlmaLinux but not required if you are on at least CentOS 8.4. Rebooting after the updates is recommended if your system received new updates. sudo dnf update -y sudo reboot
    • As of January 31, 2022 the CentOS 8 mirrorlists are offline. In order to successfully perform dnf update -y you need to update your dnf config files to point to a valid mirror. You can use the following sed commands for convenience to restore dnf to a functional state that will let you update to 8.5 and subsequently AlmaLinux
    EDIT: from Almalinux Github page here are the mirrors
    • sudo sed -i -e '/mirrorlist=http:\/\/mirrorlist.centos.org\/?release=$releasever&arch=$basearch&repo=/ s/^#*/#/' -e '/baseurl=http:\/\/mirror.centos.org\/$contentdir\/$releasever\// s/^#*/#/' -e '/^\[baseos\]/a baseurl=https://mirror.rackspace.com/centos-vault/8.5.2111/BaseOS/$basearch/os' /etc/yum.repos.d/CentOS-Linux-BaseOS.repo sudo sed -i -e '/mirrorlist=http:\/\/mirrorlist.centos.org\/?release=$releasever&arch=$basearch&repo=/ s/^#*/#/' -e '/baseurl=http:\/\/mirror.centos.org\/$contentdir\/$releasever\// s/^#*/#/' -e '/^\[appstream\]/a baseurl=https://mirror.rackspace.com/centos-vault/8.5.2111/AppStream/$basearch/os' /etc/yum.repos.d/CentOS-Linux-AppStream.repo sudo sed -i -e '/mirrorlist=http:\/\/mirrorlist.centos.org\/?release=$releasever&arch=$basearch&repo=/ s/^#*/#/' -e '/baseurl=http:\/\/mirror.centos.org\/$contentdir\/$releasever\// s/^#*/#/' -e '/^\[cr\]/a baseurl=https://mirror.rackspace.com/centos-vault/8.5.2111/ContinuousRelease/$basearch/os' /etc/yum.repos.d/CentOS-Linux-ContinuousRelease.repo sudo sed -i -e '/mirrorlist=http:\/\/mirrorlist.centos.org\/?release=$releasever&arch=$basearch&repo=/ s/^#*/#/' -e '/baseurl=http:\/\/mirror.centos.org\/$contentdir\/$releasever\// s/^#*/#/' -e '/^\[devel\]/a baseurl=https://mirror.rackspace.com/centos-vault/8.5.2111/Devel/$basearch/os' /etc/yum.repos.d/CentOS-Linux-Devel.repo sudo sed -i -e '/mirrorlist=http:\/\/mirrorlist.centos.org\/?release=$releasever&arch=$basearch&repo=/ s/^#*/#/' -e '/baseurl=http:\/\/mirror.centos.org\/$contentdir\/$releasever\// s/^#*/#/' -e '/^\[extras\]/a baseurl=https://mirror.rackspace.com/centos-vault/8.5.2111/extras/$basearch/os' /etc/yum.repos.d/CentOS-Linux-Extras.repo sudo sed -i -e '/mirrorlist=http:\/\/mirrorlist.centos.org\/?release=$releasever&arch=$basearch&repo=/ s/^#*/#/' -e '/baseurl=http:\/\/mirror.centos.org\/$contentdir\/$releasever\// s/^#*/#/' -e '/^\[fasttrack\]/a baseurl=https://mirror.rackspace.com/centos-vault/8.5.2111/fasttrack/$basearch/os' /etc/yum.repos.d/CentOS-Linux-FastTrack.repo sudo sed -i -e '/mirrorlist=http:\/\/mirrorlist.centos.org\/?release=$releasever&arch=$basearch&repo=/ s/^#*/#/' -e '/baseurl=http:\/\/mirror.centos.org\/$contentdir\/$releasever\// s/^#*/#/' -e '/^\[ha\]/a baseurl=https://mirror.rackspace.com/centos-vault/8.5.2111/HighAvailability/$basearch/os' /etc/yum.repos.d/CentOS-Linux-HighAvailability.repo sudo sed -i -e '/mirrorlist=http:\/\/mirrorlist.centos.org\/?release=$releasever&arch=$basearch&repo=/ s/^#*/#/' -e '/baseurl=http:\/\/mirror.centos.org\/$contentdir\/$releasever\// s/^#*/#/' -e '/^\[plus\]/a baseurl=https://mirror.rackspace.com/centos-vault/8.5.2111/centosplus/$basearch/os' /etc/yum.repos.d/CentOS-Linux-Plus.repo sudo sed -i -e '/mirrorlist=http:\/\/mirrorlist.centos.org\/?release=$releasever&arch=$basearch&repo=/ s/^#*/#/' -e '/baseurl=http:\/\/mirror.centos.org\/$contentdir\/$releasever\// s/^#*/#/' -e '/^\[powertools\]/a baseurl=https://mirror.rackspace.com/centos-vault/8.5.2111/PowerTools/$basearch/os' /etc/yum.repos.d/CentOS-Linux-PowerTools.repo

    you might need to update the mirrors first if your root you can exclude the sudo part for each one so you can copy and paste starting with sed example: copy and paste in terminal one by one and enter after each one so sed -i -e '/mirrorlist=http:\/\/mirrorlist.centos.org\/?release=$releasever&arch=$basearch&repo=/ s/^#*/#/' -e '/baseurl=http:\/\/mirror.centos.org\/$contentdir\/$releasever\// s/^#*/#/' -e '/^\[baseos\]/a baseurl=https://mirror.rackspace.com/centos-vault/8.5.2111/BaseOS/$basearch/os' /etc/yum.repos.d/CentOS-Linux-BaseOS.repo
    then click enter. then the next and so on. then run dnf update -y
    then reboot
    then move on the the bash almalinux-deploy.sh
    i would follow this GitHub - AlmaLinux/almalinux-deploy: EL to AlmaLinux migration tool.
