Description Karel Srot 2019-02-25 07:37:11 UTC

Description of problem:

dnf man page has following example:

  dnf alias add update="\update --skip-broken --disableexcludes=all --obsoletes"

however this example doesn't work.

1. the command above should be working
2. man page should explain the \ notation

# dnf update
No such command: \update. Please use /usr/bin/dnf --help


Version-Release number of selected component (if applicable):
dnf-4.0.9.2-4.el8.noarch

Comment 3 Brandon Bennett 2019-12-16 15:56:35 UTC

This exists for Fedora 31 as well.

$ sudo dnf alias add update='\update --skip-broken --disablerepo=cpe*'
Aliases added: update
$ sudo dnf update
No such command: \update. Please use /usr/bin/dnf --help
It could be a DNF plugin command, try: "dnf install 'dnf-command(\update)'"
