UPS package missing libraries in Rocky 10.1

Rocky Linux Help & Support

I have installed Rocky Linux 10.1 (Red Quartz) and I am now trying to set up NUT in standalone mode with a generic USB controlled UPS. I installed it using:

root@shi:~# dnf install nut

Complete!

However it appears to be missing some libraries:

root@shi:~# nutconf --is-configured
Cannot load USB library (libusb-1.0.so) : file not found. USB search disabled.
Cannot load SNMP library (libnetsnmp.so) : file not found. SNMP search disabled.

false

I’m going to need that USB one so I started there:

root@shi:~# rpm -qa | grep -i libusb
libusb1-1.0.28-1.el10.x86_64
libusb-compat-0.1-0.1.8-9.el10_0.x86_64
root@shi:~# dnf provides libusb-1.0.so
Last metadata expiration check: 0:23:16 ago on Fri 02 Jan 2026 09:31:59.
Error: No matches found. If searching for a file, try specifying the full path or using a wildcard prefix ("*/") at the beginning.

Tried other things, such as installing libusbx and nut-devel but they didn’t help with the missing libusb-1.0.so.

I’m guessing that it is an issue with the package manager not knowing the full dependencies of Nut? Not sure of the best path forward so would welcome suggestions.

Looks like libusb1-devel might be what you need.

dnf provides "*/libusb-1.0.so"

Not necessarily. In almost all circumstances, especially from packages from EPEL (thus the fedora project), when a package is built, it will determine relevant dependencies automatically and the maintainer of the package can optionally add in additional dependencies.

[root@idp ~]# dnf whatprovides \*/libusb-1.0.so*

Using dnf you can try to find the relevant library package. As shown here, it’s libusb1. (You do not need to use the devel package unless absolutely required).

Thanks, I was over estimating what “dnf provides” could do. Was able to get it working now.

For others who run into the issue here is the key steps. Thanks to @linde and @label for their fast and useful replies.

First installed these:

dnf install libusb1-devel
dnf install net-snmp-devel
dnf install neon-devel
dnf install avahi-devel

libfreeipmi.so was a bit more work. I already had it with a longer file name, it comes from freeipmi-1.6.14-4.el10.x86_64. So I created a soft link with the needed file name:

cd /usr/lib64/
ln -s libfreeipmi.so.17.2.12 libfreeipmi.so

With that it appears to run ok.
