message saying "Another app is currently holding the yum lock; waiting for it to exit..." when trying to install Ansible

+1 vote

I've installed Ansible on Oracle's Virtual Machine and mounted /dev/sr0 and configured system.repo under /etc/yum.repos.d as below.

 [SYSTEM]
    name=rhel6
    baseurl=file:///mnt
    gpgcheck=0
    enabled=1

But the yum command isn't working, I get this error;

Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again

I made a few chnages and then I got another error;

Existing lock /var/run/yum.pid: another copy is running as pid 2448. Another app is currently holding the yum lock; waiting for it to exit...

Follow these steps;

  • Install epel repo properly, looks like it hasn't been installed correctly
yum search epel
yum install epel-release
  • Restart your yum service:

service yum restart
  • Find the ansible package:

yum search ansible
  • And then install ansible

yum install ansible

Hi,

I may not sure about the answer but could you please try it by following way:

Generally, this error will encounter due to another instance is running yum command at the same time check which process is running by using PID in the output error and kill the process.

Once the process is killed you can try it once.

Below is the command to kill the process

kill 1432(PID value)--Here I have taken an example

Below is the command to find which process is taking more :

ps -ef
