UBUNTU 24.04 LTS

[whackl]

Hi there,
Ubuntu 24.04 lts is on its was, will there be aversion for the New lts ?

[l3ifk]

Is there any update on this??

[cemoral]

For me howdy was removed during the installation of 24.04 as unsupported software. I made it work after re-installing it with following the steps on the guide.

[l3ifk]

When adding the repository it says that the repository does not have a release file. When trying sudo apt install howdy, I get following output:

Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Package howdy is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'howdy' has no installation candidate

Installing with the .deb file is also not possible because it will just stay at "preparing..." forever...

Edit: That is the repository error:

E: The repository 'https://ppa.launchpadcontent.net/boltgolt/howdy/ubuntu noble Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

Copied the package to Ubuntu Noble on launchpad, should be available within another hour or so. Thanks for reporting!

Thank you the install and setup works. Unfortunately my laptop does not try to use howdy even after a reboot.. It is enabled in PAM and I setup face models.
Also when using howdy test, I get a red circle around my face but never a green one. So it seems like howdy recognizes a face but not that it's mine? But I'm not sure about that one.

Edit: Even after a clean install of Ubutnu 24.04, which solved other issues I had, howdy's behavior is still the same.

Also this error comes up during the install, I don't know if this causes a issues:

Hi, how did you install it on Ubuntu 24.04 with success? Because I have tried it according to description, added the repository, then after update I did install with apt, but at the end I got the following error message:
Sub-process /usr/bin/dpkg returned an error code (1)
Could somebody give me a detailed step by step howto?

What else did it say before the last error. Could you give the whole error?

Yes

And something else to it: I installed it with success on MX23, that is debian 12.

I have successfully installed howdy on 24.04 such that the test and configuration works fine.
I do see my face and the IR emitter is turned on.
Although everything seems to be working, then howdy is not being used at login or for any operation requiring the password. Could 24.04 have changed something and forbid howdy to work correctly?

[cemoral]

I did a manual installation with meson and the packages that should be on global pip like this
$ sudo pip install --break-system-packages dlib

[enbzz]

externally-managed-environment

I solved this by using:
sudo mv /usr/lib/python3.11/EXTERNALLY-MANAGED /usr/lib/python3.11/EXTERNALLY-MANAGED.old

I have the exact same problem. Is there any fix for this? I already checked in sudo pam-auth-update and howdy is enabled there.

[aszabo70]

I could solve the issue but only with howdy_2.6.1.deb. I know this is a little bit old version but works.

[l3ifk]

unfortunately when trying to install the .deb you mentioned. It's just saying "preparing..." forever without actually installing anything...

[aszabo70]

Interesting, I had only one problem with ConfigParser in pam.py, it should be changed to configparser.

Interesting, it looks just like mine. I tried installing the .deb within the terminal to get the error while installing and I got this:

I manually installed the beta version Howdy 3.0.0 BETA on Ubuntu 24.04. Problem with
No module named dlib
solved with:
sudo pip install --break-system-packages dlib-bin

[l3ifk]

Thanks for the suggesting but I still get the same error while install howdy 3.0.0 BETA, even when trying to install the beta version.

The distro packagers put that EXTERNALLY-MANAGED file there to prevent anything other than apt/dpkg managing libraries installed in the system python. You can read about it here: https://packaging.python.org/en/latest/specifications/externally-managed-environments/

This is done to protect the system from breakage... ironically including security issues. So if you're thinking of moving that file, you can read more about what that actually does above.
