Resolving Dependencies
There are unfinished transactions remaining. You might consider running yum-complete-transaction, or "yum-complete-transaction --cleanup-only" and "yum history redo last", first to finish them. If those don't work you'll have to try removing/installing packages by hand (maybe package-cleanup can help).

try this -

rpm --import https://pkg.jenkins.io/redhat/jenkins.io.key

As mentioned here

I got the below error

# rpm --import https://pkg.jenkins.io/redhat/jenkins.io.key



curl: (7) Failed connect to pkg.jenkins.io:443; Connection timed out
error: https://pkg.jenkins.io/redhat/jenkins.io.key: import read failed(2).

I believe this is the same problem as in your other thread: https://www.linuxquestions.org/quest...pm-4175631751/

Agree with jsbjsb001. You can try to manually download the key and import locally.
This is something the repo maintainer needs to fix.

I can do it by first wget to dowanload and then import .

however I still wonder why I can't directly import ?

There seems to be some problem in you name resolution. If wget works but curl does not, I suggest adding the '-v' flag to the curl command, and the '-d' flag to the wget command, so you can see in more detail the differences.
