YUM update information


Hi.
Just a question of curiosity, I trust whatever YUM wants to give me.
How do I go about getting information about an update before I let YUM do it?
For instance, I'm having a little trouble with Teamviewer, so my last
Code:
# yum update
gave me this:
Code:
 teamviewer        x86_64        13.2.13582-0           teamviewer         12 M
and I was curious what it was: fixing, adding or deleting; to see if it was the issues I was having.

I just said "yes do the update" because regardless, I want to install whatever YUM to install.

Thanks.

If I understand your question correctly;

Code:
yum info teamviewer
or

Code:
yum deplist teamviewer
If you want to list teamviewer's dependencies for the yum command above.

And to see what's going to happen before using the commands jsbjsb001 posted:
Code:
yum check-update
will give you a list of all pending updates.

Code:
man yum
or
Code:
yum -help
will show and explain yum commands.

Thanks.
Yes, the command examples gives me information about what YUM needs to implement, etc.

But the question was, in this particular case, was the update that yum was given by teamviewer (or any other package), what was that supposed to fix?
I figure there are always release notes somewhere for the curious.

btw, I don't use 'check-update', I let it execute 'update', because that gives me a pause point so I can check the updates it wants to do -- if something gives ME pause, I say 'N' when it asks permission to continue.

YUM then gives me the line I need so as to let YUM pick up where it left off before it quits.

I then can do whatever I need to before I cut & paste that line to have YUM pick up where it left off and continue.

Sometimes if it's a particularly large update, I say 'NO' then run 'rkhunter' to ensure my system is clean, afterwards I let YUM pick up where it left off.

I do my 'rkhunter' afterwards like I always do after a YUM update, but am assured that any problems it picks up about certain important files having been changed, I know it's been changed by the update I just did and not something nefarious.

I'm sure that's true, but I don't see a way for yum to provide that information. As you say, info just says what the package is.

My best guess would be to search your distribution's website or the 'net in general for something like "teamviewer release notes" or the like.

If you have the yum-changelog plugin installed, you can use 'yum update <package> --changelog', and it will show you the changelog differences in the updated version before confirming the update. The changelogs are not usually detailed, but will usually indicate bugs fixed or CVEs resolved.

You can also use it to show you 'yum changelog <package>' for any package or changelog since a particular date.
