[SOLVED] How to install audacity on centos 8

System info:

Code:

$ cat /etc/centos-release
CentOS Linux release 8.3.2011

$ uname -a
Linux localhost.localdomain 4.18.0-240.1.1.el8_3.x86_64 #1 SMP Thu Nov 19 17:20:08 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

Hi

I tried to install audacity by following the instructions on this link:
https://www.how2shout.com/how-to/how...n_on_CentOS_87

which tells you to install snap, then use that to install audacity.

All seemed to go well, but when I try to run audacity I get the following error:

Code:

$ audacity
Warning: GTK2 does not support Wayland!
Trying to route ALSA through PulseAudio...
Gtk-Message: 15:01:34.948: Failed to load module "pk-gtk-module"

The first time I did it a warning dialog with an exclamation mark in a triangle comes up with a message, which I did not manage to capture (after the first time it did not repeat), and an option to 'Wait' or 'Cancel'.

When I waited long enough the audacity window came up after a while with further errors spat out at the command line:

Code:

$ audacity

Can anyone tell me if this is the correct way to install audacity on centos 8 ?

Does anyone know what these errors mean ? It looks like I have some dependencies missing (though the audacity app still comes up - I have not tried to use it yet).

Well, why go down the Snap route at all? Audacity 2.3.3 is provided by EPEL8 repo, and their version is linked against GTK3.

Code:

sudo dnf --enablerepo=extras install epel-release
sudo dnf -y --refresh upgrade
sudo dnf install audacity

Or it absolutely must be the latest version? Even then, for CentOS, I'd choose Flatpak over Snap.

Thank you very much for the reply.

I think I was mis-led by the fact that almost all my searches indicated that snap should be used to install audacity on centos, combined with the the fact that attempting to use dnf came back with No packages available.

I should get into the habit of upgrading before trying to install - and yes, after that, the install worked.

Apologies for the spam.

I did not know about flathub, so thank you for the tip there.
