x-www-browser in Xubuntu is broken, affects Ubiquity

[Daniel Richard G.]

I am attempting to install a system using the released Xubuntu 22.04.1 (jammy) installer.

An error occurred during the install process, and then the installer failed to open a browser to report the issue. (This bug report concerns the latter fault.)

Below is an excerpt from syslog. It appears that x-www-browser has not been adjusted to use Firefox:

Thanks for your bug report. Indeed, x-www-browser is pointing at chromium-browser, which seems to be installed for some reason. We'll investigate.

xubuntu@xubuntu:~$ ls -lart /usr/bin/x-www-browser
lrwxrwxrwx 1 root root 31 Sep 18 2020 /usr/bin/x-www-browser -> /etc/alternatives/x-www-browser

xubuntu@xubuntu:~$ ls -lart /etc/alternatives/x-www-browser
lrwxrwxrwx 1 root root 25 Sep 18 2020 /etc/alternatives/x-www-browser -> /usr/bin/chromium-browser
