Lost dnf after migration from Centos7/8 to AlmaLinux

Question

I migrated my CentOS 7 to 8 and then to AlmaLinux, but in the process i lost dnf and yum. Now i try to fix, but have a lot of problems with dependencies etc. Only rpm is working so i have to do all “manually”.

If i try:

rpm -ivh https://vault.centos.org/centos/8/BaseOS/x86_64/os/Packages/rpm-libs-4.14.3-19.el8.x86_64.rpm

i get an error:

Failed dependencies: rpm = 4.14.3-19.el8 is needed by rpm-libs-4.14.3-19.el8.x86_64

but if try:

rpm -ivh https://repo.almalinux.org/almalinux/8/BaseOS/x86_64/os/Packages/rpm-4.14.3-19.el8_5.2.x86_64.rpm

i get a lot of conflicts:

How can i fix it? I have only an remote access (via ssh or webmin) to this system. I have an Centos 7 and AlmaLinux on VirtualBox, so i can possibly transfer some files from there.

Answer 1

You still have packages from EL7. This means you failed to upgrade from CentOS 7 to CentOS 8. This is not officially supported. But it is technically possible - https://www.tecmint.com/upgrade-centos-7-to-centos-8/

At this stage of your brokenness, it will be much much easier to wipe the OS and install Alma from scratch.
