RPM Hung

Check if there’s a runaway rpm process. This returns number of processes that are running.

ps -ef | grep rpm | wc -l

Kill it.

killall -9 rpm

You should be able to run yum updates from this point on.

Checking Yum Transaction Logs

Check if package is on the system.

rpm -q httpd
httpd-2.4.6-97.el7.centos.x86_64

Check the history logs.

yum history list
Loaded plugins: fastestmirror
ID     | Login user               | Date and time    | Action(s)      | Altered
-------------------------------------------------------------------------------
   115 | System <unset>           | 2021-02-01 03:40 | Update         |    1
   114 | System <unset>           | 2021-02-01 02:03 | I, U           |   10
   113 | System <unset>           | 2021-01-29 19:54 | Update         |    1
   112 | System <unset>           | 2021-01-21 14:41 | Update         |    1

Check detail transaction id.

yum history info 114 | grep python 
    Updated python-perf-3.10.0-1160.6.1.el7.x86_64          @updates
    Updated python-sss-1.16.5-10.el7_9.5.x86_64             @your-repo
    Updated python-sssdconfig-1.16.5-10.el7_9.5.noarch      @your-repo

It looks like python was updated in transaction id #114.

Yum localinstall

Here’s how to install a RPM locally. Download the RPM first.

Then install RPM from a local file.

yum localinstall /path/to/rpmfile1.rpm
yum localinstall /path/to/rpmfile2.rpm
