Updated Centos VM to Oracle Linux

I was using Centos Linux for Nethack programming and playing on my home laptop. Evidently Centos is going away at the end of 2021 and Tim Hall had a post about moving Centos to Oracle Linux. So, I did it. The theory was that I would still be able to get updates from Oracle in 2022 and beyond.

I followed the instructions from here: https://linux.oracle.com/switch/centos/

I did this while logged in as root:

git clone https://github.com/oracle/centos2ol
cd centos2ol
bash centos2ol.sh

I got this error:

Error: Package: tkinter-2.7.5-88.el7.x86_64 (@base/7)
           Requires: python = 2.7.5-88.el7

I do not need tkinter so I just removed it:

yum remove tkinter-2.7.5-88.el7.x86_64

Then I just did a yum update and it seemed fine. The only odd thing is that when I reboot, I get an error like this:

integrity: Unable to open file: /etc/keys/x509_ima.der (-2)

I looked up this message and it seems like I cannot fix it but can just ignore it. Not a big deal but would be cleaner without it.

It was easy to switch but I just thought I would document the two error messages, even though they did not cause any problems.
