Whoa!

What will happen if I run a "yum update" on a CO6 machine? We have it run automatically at reboot and I need to know what will happen so I can see if the rest of the scripts we run at startup will be OK.

Yes we are updating them, but it's hard to do when you can't go onsite due to COVID.

You will get every system running through messages like this

[root@linode01 ~]# yum update

until it finds some mirror which will work (that one mirror seems to be updating for everyone in the world so is very slow).

or it will do the following:

[root@linode01 ~]# yum clean all
Loaded plugins: etckeeper, fastestmirror
Cleaning repos: base cr epel epel-testing extras updates
Cleaning up Everything
Cleaning up list of fastest mirrors
[root@linode01 ~]# yum update

Setting up Update Process
Determining fastest mirrors
YumRepo Error: All mirror URLs are not using ftp, http[s] or file.
Eg. Invalid release/repo/arch combination/
removing mirrorlist with no valid mirrors: /var/cache/yum/i386/6/base/mirrorlist.txt
Error: Cannot find a valid baseurl for repo: base

[root@linode01 ~]# echo $?
1

[root@linode01 ~]# yum list all
Loaded plugins: etckeeper, fastestmirror
Loading mirror speeds from cached hostfile
YumRepo Error: All mirror URLs are not using ftp, http[s] or file.

so basically the system can not find anything/do anything until a working mirror is there.

I'm not really very happy with this throwing an error.

I get it. People need to upgrade. But breaking things that are part of automated processes is a crappy way to get the message across.

As I mentioned, upgrades will take some time still, and now I have more work to deal with our unupgraded systems, so now it will take even longer to upgrade.

Thanks a bunch.

(Sorry for the sarcasm, but this is not a nice way to deal with the situation).
