.`clevis-systemd` no longer depends on `nc`
With this enhancement, the `clevis-systemd` package no longer depends on the `nc` package. The dependency did not work correctly when used with Extra Packages for Enterprise Linux (EPEL).

The latest clevis release upstream (v16) even dropped netcat altogether as a requirement, since systemd provides a utility that can do the task netcat was being used for and it's already available -- as this is a systemd unlocker.

Looks like this is link to your pull ... that should work too. https://github.com/latchset/clevis/pull/266 Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.

Description of problem: clevis-systemd uses ncat in /usr/libexec/clevis-luks-askpass However, the clevis-systemd RPM has dependency on nc Not a big issue when only RHEL BaseOs & AppStream repos are in use; however, in EPEL the netcat RPM exists and it too provides nc, but NOT ncat binary clevis-systemd actually uses. Version-Release number of selected component (if applicable): clevis-systemd-13-3.el8 How reproducible: 100% Steps to Reproduce: 1. Look at what the RPM requires # rpm -qp --requires rhel-8-for-x86_64-appstream-rpms/Packages/c/clevis- systemd-13-3.el8.x86_64.rpm | head -n 4 /bin/bash /bin/sh clevis-luks(x86-64) = 13-3.el8 nc 2. Looking at script the RPM provides, can see clearly it uses ncat (not nc) # grep -n ncat /usr/libexec/clevis-luks-askpass 60: echo -n "+$pt" | ncat -U -u --send-only "$s" 3. And can see that nc is provided by both nmap-ncat (AppStream) & netcat (EPEL) # dnf --repo rhel-8-for-x86_64-baseos-rpms --repo rhel-8-for-x86_64-appstream-rpms --repo epel whatprovides nc | grep -v @System | grep -B1 Repo netcat-1.217-3.el8.x86_64 : OpenBSD netcat to read and write data across connections using TCP or UDP Repo : epel -- nmap-ncat-2:7.70-4.el8.x86_64 : Nmap's Netcat replacement Repo : rhel-8-for-x86_64-appstream-rpms -- nmap-ncat-2:7.70-5.el8.x86_64 : Nmap's Netcat replacement Repo : rhel-8-for-x86_64-appstream-rpms Actual results: With netcat from EPEL install (or even selected by dnf when both repos enabled) to meet the 'nc' require, clevis fails and are unable to boot/mount an NBDE system you just installed. Expected results: The requires should match the binary it is using to make sure the actual required binary is installed Additional info: Here can see just nc binary for netcat from EPEL # rpm -qp --list ./netcat-1.217-3.el8.x86_64.rpm | grep bin/nc /usr/bin/nc And nmap-ncat provides # rpm -q --list nmap-ncat | grep bin/nc /usr/bin/nc /usr/bin/ncat Looking at provides, pehaps best to set require on nmap-ncat ... since ncat isn't explicitly listed in provides? # rpm -q --provides nmap-ncat nc nc6 nmap-ncat = 2:7.70-5.el8 nmap-ncat(x86-64) = 2:7.70-5.el8
