Hi Support,

I am having difficulty installed NRPE client on Ubuntu server. Below is the install.log file. Can you please let me know how to fix this issue?

gawk is already the newest version (1:4.1.3+dfsg-0.1).
You might want to run 'apt-get -f install' to correct these:

Nagios Linux Agent Installation Log


Thanks,

I would try fixing your expired GPG keys, or removing the vmware related repositories from APT, then attempting to install NRPE again.

I would also make sure APT is pointed to the correct PPAs and can access common packages like cpp. There are some standard Linux packages that NRPE requires, so if the VMWare repository is the only one configured in APT that will cause some issues.

I also believe you need to remove the vmware related repositories, which are causing the error. After this, run: then proceed with the installation of the linux agent by following the document below:

Thanks, I will try it on server and will update the post.

Sounds good, let us know

All good now. Thanks

Glad to hear it is resolved. Locking
