When installing Debian 12 using the Calamares from the welcome screen a error appears when selecting "release notes". The error is "failed to execute default web browser" This occurs from a fresh install of a Live ISO. Does anyone know the cause ?
Calamares install error
- Thread starter johnlinux
- Start date
@johnlinux - well spotted 
After reading the above, I checked it for myself with a Debian 12 Cinnamon I have on a stick.
I had a negative result on the three options
I did not even get the error message you got.
So there is a glitch in that screen of the installer, but it does not prevent you from progressing further with the install.
You could report it to Debian (perhaps check first in their forum to see if it has already been noted).
In the meantime, you can read the release notes here

The IO error would make me nervous... and I'd be most checking for problems with your install media; so I'd switch to terminal & explore system logs hoping for clues...
- Did you verify ISO after download to ensure it was perfect; whilst download problems are extremely rare; they do occur (less than 1% of ISO downloads in my experience)
- Did you verify ISO write to your media; this is where I have more issues; with >3% failures here; whilst that's not common issue, for me that's many failures per year so I'm always checking for it...
Normal exploration of system logs (systemd journal, dmesg), are useful, or starting
I install Debian very rarely; so I can't help there, but that is where I'd look if I saw the message on Ubuntu installs using the calamares installer (three flavors used calamares at 24.04).

calamares from terminal (as messages can be easier to find when done this way) can be used.I install Debian very rarely; so I can't help there, but that is where I'd look if I saw the message on Ubuntu installs using the calamares installer (three flavors used calamares at 24.04).

The error means that your don't have default web browser set.
To fix it, find "default applications" settings somewhere in desktop settings and set it to Firefox or which ever browser you have installed.
