[elrepo] CentOS 8 - cannot upgrade kernel-ml

[Olaf Frączyk]

Hello,

I have installed kernel-ml-5.3.8-1.el8.elrepo.x86_64 - it worked fine.

Now, when I try dnf upgrade (or yum update) I get the following:

Error:
  Problem 1: cannot install both kernel-ml-5.5.7-1.el8.elrepo.x86_64 and 
kernel-ml-5.3.8-1.el8.elrepo.x86_64
   - cannot install the best update candidate for package 
kernel-ml-5.3.8-1.el8.elrepo.x86_64
   - problem with installed package kernel-ml-5.3.8-1.el8.elrepo.x86_64
  Problem 2: cannot install both 
kernel-ml-core-5.5.7-1.el8.elrepo.x86_64 and 
kernel-ml-core-5.3.8-1.el8.elrepo.x86_64
   - cannot install the best update candidate for package 
kernel-ml-core-5.3.8-1.el8.elrepo.x86_64
   - problem with installed package kernel-ml-core-5.3.8-1.el8.elrepo.x86_64
  Problem 3: cannot install both 
kernel-ml-devel-5.5.7-1.el8.elrepo.x86_64 and 
kernel-ml-devel-5.3.8-1.el8.elrepo.x86_64
   - cannot install the best update candidate for package 
kernel-ml-devel-5.3.8-1.el8.elrepo.x86_64
   - problem with installed package 
kernel-ml-devel-5.3.8-1.el8.elrepo.x86_64
  Problem 4: cannot install both 
kernel-ml-modules-5.5.7-1.el8.elrepo.x86_64 and 
kernel-ml-modules-5.3.8-1.el8.elrepo.x86_64
   - cannot install the best update candidate for package 
kernel-ml-modules-5.3.8-1.el8.elrepo.x86_64
   - problem with installed package 
kernel-ml-modules-5.3.8-1.el8.elrepo.x86_64
(try to add '--allowerasing' to command line to replace conflicting 
packages or '--skip-broken' to skip uninstallable packages or '--nobest' 
to use not only best candidate packages)

What can I do to fix this problem?

I don't want to erase current kernel, so I can go back if any problem 
happens. Just like with the regular kernels.

Best regards,
