redhat / centos upgrade warning

[peterwalkley]

Watch out if you are running redhat or centos: there is a stuffed update that can cause your system to become unbootable: https://bugzilla.redhat.com/show_bug.cgi?id=1861977

I ran a yum update as normal and its knackered, none of the suggestions on various threads fix it for me as yet.

EDIT: ISSUE IS FIXED.

If it helps any, I'm running Centos 8.2.2004, not 7. It was just last night I ran the yum update (about 8pm 31st July ...) IF they've fixed it, the fixes aren't on the mirrors yet and I'm not noticing anything new when I try an update again - once I can get in via the troubleshooting mode (and also chroot and get the networking running).

If you've not updated yet, I'd advise very strongly to not do it for at least a week until the picture is clearer.

Phew !

Recovered mine using the instructions in here: https://forums.centos.org/viewtopic.php?f=54&t=75227&sid=a470bed7e8c8e1167648d395b6fd2a50

That was .... fun

It looks safe to do a normal yum update if you haven't already done it. The broken version of the shim has been superseded so won't get installed. Brown alert over.
