"dnf: command not found" on fresh install of F41

w-bruce-w · December 28, 2024, 10:48pm

Hi,

I’ve just installed F41 Workstation edition and after a few hours I’m unable to use the “sudo dnf” command in the terminal.

It was working right after the install so, I think something went wrong with an update.

Is there a way to fix that?

litemotiv · December 28, 2024, 11:07pm

Can you check if the program is still physically on the drive?

$ which dnf

/usr/bin/dnf

$ rpm -qi dnf5

Name        : dnf5
Version     : 5.2.8.1
Release     : 2.fc41
Architecture: x86_64
[etc...]

w-bruce-w · December 29, 2024, 12:56am

It doesn’t seems to be installed anymore…

$ which dnf
/usr/bin/which: no dnf in (/home/admin/.local/bin:/home/admin/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin)

$ rpm -qi dnf5
package dnf5 is not installed

(tried also with dnf3, just in case)

It should be pretty easy to reinstall it, on my PC I have Fedora 41 and this command shows the URL to the package:

dnf download --url --resolve dnf5.x86_64

Updating and loading repositories:
Repositories loaded.
http://mirror.math.princeton.edu/pub/fedora/linux/updates/41/Everything/x86_64/Packages/d/dnf5-5.2.8.1-2.fc41.x86_64.rpm

Since your dnf is gone and you obviously can’t use dnf to install it then, you can use “rpm” command in network URL mode:

sudo rpm -i http://mirror.math.princeton.edu/pub/fedora/linux/updates/41/Everything/x86_64/Packages/d/dnf5-5.2.8.1-2.fc41.x86_64.rpm

Then immediately do some dnf commands like:

sudo dnf upgrade

and confirm it’s working

w-bruce-w · December 29, 2024, 1:24pm

I tried but I have missing dependencies as well:

$ sudo rpm -i http://mirror.math.princeton.edu/pub/fedora/linux/updates/41/Everything/x86_64/Packages/d/dnf5-5.2.8.1-2.fc41.x86_64.rpm
error: Failed dependencies:

	libsdbus-c++.so.1()(64bit) is needed by dnf5-5.2.8.1-2.fc41.x86_64

I can’t find a way to install these without using “dnf”. I tried to use “rpm” but then I get the same issue:

$ sudo rpm -i https://dl.fedoraproject.org/pub/fedora/linux/updates/41/Everything/x86_64/Packages/p/perl-libdnf5-cli-5.2.8.1-2.fc41.x86_64.rpm

Did you try with dnf4 by any chance? It should be available on F41.

dnf4 --version
4.22.0
  Installed: rpm-0:4.20.0-1.fc41.x86_64 at Sat 12 Oct 2024 04:31:16 PM GMT
  Built    : Fedora Project at Tue 08 Oct 2024 03:18:49 PM GMT

If available, you can use it to reinstall dnf5.

w-bruce-w · December 29, 2024, 3:39pm

Yes same thing. It’s not available

One of the update litterally removed the entire ‘dnf’ functionnality and its dependencies.

marko3209 · December 29, 2024, 4:00pm

I can’t find a way to install these without using “dnf”. I tried to use “rpm” but then I get the same issue

You keep adding packages to the “rpm -i …” until it works

I can run this on my system which “works” because my dnf5 is okay


dnf download --resolve --alldeps --url dnf5.x86_64 | grep dnf

which shows three packages–> dnf5 libdnf5 libdnf5-cli

http://ziply.mm.fcix.net/fedora/linux/updates/41/Everything/x86_64/Packages/d/dnf5-5.2.8.1-2.fc41.x86_64.rpm
http://ziply.mm.fcix.net/fedora/linux/updates/41/Everything/x86_64/Packages/l/libdnf5-5.2.8.1-2.fc41.x86_64.rpm
http://ziply.mm.fcix.net/fedora/linux/updates/41/Everything/x86_64/Packages/l/libdnf5-cli-5.2.8.1-2.fc41.x86_64.rpm

The true resolved deps for dnf5 is huge (~ 115 packages) but I’m going to assume here that only the direct packages for dnf5 got removed (that have “dnf” in the name). So I got those three rpms above by doing a resolve on all “alldeps” for dnf5 so it doesn’t skip the ones on my local system and filtered to “dnf”.

so try the rpm command for all three rpms

sudo rpm -i http://ziply.mm.fcix.net/fedora/linux/updates/41/Everything/x86_64/Packages/d/dnf5-5.2.8.1-2.fc41.x86_64.rpm  http://ziply.mm.fcix.net/fedora/linux/updates/41/Everything/x86_64/Packages/l/libdnf5-5.2.8.1-2.fc41.x86_64.rpm  http://ziply.mm.fcix.net/fedora/linux/updates/41/Everything/x86_64/Packages/l/libdnf5-cli-5.2.8.1-2.fc41.x86_64.rpm```

litemotiv · December 29, 2024, 4:07pm

Might also be interesting to see if the dnf logs are still there, to find out what triggered the removal:

$ ls -la /var/log/dnf*

w-bruce-w · December 29, 2024, 5:05pm

One more seems to be missing:

error: Failed dependencies:
	libsdbus-c++.so.1()(64bit) is needed by dnf5-5.2.8.1-2.fc41.x86_64

But I can’t find it in Packages folder you used for the other.

w-bruce-w · December 29, 2024, 5:07pm

Which one should have the information?

-rw-r--r--. 1 root root  463037 Dec 28 13:18 /var/log/dnf5.log

marko3209 · December 29, 2024, 5:28pm

That library is in a package of a different name, I found it with --whatprovides

dnf5 repoquery --whatprovides=\*/libsdbus-c++.so.1

sdbus-cpp-0:1.5.0-3.fc41.x86_64

So it looks like you didn’t simply remove two or three rpms but a bunch.

The URL to that is

http://ziply.mm.fcix.net/fedora/linux/releases/41/Everything/x86_64/os/Packages/s/sdbus-cpp-1.5.0-3.fc41.x86_64.rpm

If you want to try for four URLs.

sudo rpm -i  \
http://ziply.mm.fcix.net/fedora/linux/updates/41/Everything/x86_64/Packages/d/dnf5-5.2.8.1-2.fc41.x86_64.rpm \
http://ziply.mm.fcix.net/fedora/linux/updates/41/Everything/x86_64/Packages/l/libdnf5-5.2.8.1-2.fc41.x86_64.rpm \
http://ziply.mm.fcix.net/fedora/linux/updates/41/Everything/x86_64/Packages/l/libdnf5-cli-5.2.8.1-2.fc41.x86_64.rpm \
http://ziply.mm.fcix.net/fedora/linux/releases/41/Everything/x86_64/os/Packages/s/sdbus-cpp-1.5.0-3.fc41.x86_64.rpm

But I’d look in /var/log/dnf5.log for lines with “uninstall” in them that were removing those dnf packages. I removed a package I don’t need called “qt5-qttools” just to see what the dnf5.log logging looks like and found it was:

grep qt5-qttools dnf5*log

2024-12-29T17:22:23+0000 [22486] INFO — DNF5 launched with arguments: “dnf5 rm qt5-qttools” —
2024-12-29T17:22:26+0000 [22486] INFO RPM callback uninstall start “qt5-qttools-0:5.15.15-1.fc41.x86_64” total 12
2024-12-29T17:22:26+0000 [22486] INFO RPM callback uninstall stop “qt5-qttools-0:5.15.15-1.fc41.x86_64” amount 12 total 12

So seeing “uninstall” seems to point to removing packages.

is pkcon still available?

/usr/bin/pkcon install dnf5

marko3209 · December 29, 2024, 5:38pm

Doesn’t pkcon underneath call to dnf (both of dnf4 or 5 he doesn’t have) so that wouldn’t help him?

Mine says:

pkcon backend-details

Name:           dnf
Description:    Dnf
Author: Richard Hughes <richard@hughsie.com>

w-bruce-w · December 29, 2024, 5:42pm

@grumpey Thanks a lot! I ran

sudo pkcon install dnf5

and it fixed everything and I am now able to use dnf again (version 5.2.8.1).

@marko3209
I check the log and couldn’t find any “uninstall” in it. So, still no clue what could have caused the issue…

marko3209 · December 29, 2024, 5:44pm

dnf5 log is so verbose that the junk rotates into older logs quickly, so it might be in dnf5.log.4 or something. If you want to check try

grep uninstall dnf5.log* | grep dnf
