这个问题Another app is currently holding the yum lock; waiting for it to exit... The other application is: yum

This error message indicates that another application is currently using the yum package manager, and as a result, the system cannot perform any yum-related tasks until the other application is finished. You will need to wait until the other application is done or manually terminate it to free up the yum lock. Alternatively, you can try running the yum command with the "--skip-broken" option to bypass the lock and continue with the installation process.
