Learn quickly how to resolve “error: Failed dependencies:” error. This error comes when you do not have installed the dependent packages on the server.

Error: While installing packages you must have come across following error:

error: Failed dependencies:

Sample output of the Error is below while installing kernel:

[root@ip-172-31-9-104 kernel_pkg]# rpm -ivh kernel-3.10.0-514.10.2.el7.x86_64.rpm
error: Failed dependencies:
linux-firmware >= 20160830-49 is needed by kernel-3.10.0-514.10.2.el7.x86_64
xfsprogs < 4.3.0 conflicts with kernel-3.10.0-514.10.2.el7.x86_64
kmod < 20-9 conflicts with kernel-3.10.0-514.10.2.el7.x86_64

In the above output while upgrading the kernel, system needs rpm packages mentioned in the output.

How to resolve “error: Failed dependencies:”

• Install the latest package using YUM repository:

yum install <Pkg name>

in Our case

yum install kernel

• You can also download the packages required manually using RHN connected system and then move it to your offline server. Below command given on the yum server which is connected to RHN network.

yumdownloader --resolve  --destdir <download dir location> <Pkg Name>

e.g. In Our case for kernel packages

[root@ip-172-31-8-245 ~]# yumdownloader --resolve --destdir /var/tmp kernel

In our case we have downloaded all the dependent packages under the directory /var/tmp.

• Once you moved the packages to offline system, go to that particular directory where packages are downloaded and give below command to resolve automatic dependency.

#yum localinstall *.rpm
