How to change priorities of x-www-browser?
You can change the priority with:
sudo update-alternatives --install /usr/bin/x-www-browser x-www-browser google-chrome-stable <priority_as_integer>
Example:
before
$ sudo update-alternatives --config x-www-browser
There are 2 choices for the alternative x-www-browser (providing /usr/bin/x-www-browser).
Selection Path Priority Status
------------------------------------------------------------
* 0 /usr/bin/google-chrome-beta 150 auto mode
1 /usr/bin/firefox 150 manual mode
2 /usr/bin/google-chrome-beta 150 manual mode
after:
$ sudo update-alternatives --install /usr/bin/x-www-browser x-www-browser /usr/bin/google-chrome-beta 50
update-alternatives: using /usr/bin/firefox to provide /usr/bin/x-www-browser (x-www-browser) in auto mode
$ sudo update-alternatives --config x-www-browser
There are 2 choices for the alternative x-www-browser (providing /usr/bin/x-www-browser).
Selection Path Priority Status
------------------------------------------------------------
* 0 /usr/bin/firefox 150 auto mode
1 /usr/bin/firefox 150 manual mode
2 /usr/bin/google-chrome-beta 50 manual mode
In short: edit /var/lib/dpkg/alternatives/x-www-browser and change priority inside
DETAILS
An easiest and the must answer is to edit the administrative update-alternative files found in the /var/lib/dpkg/alternatives
So edit the x-www-browser file
sudo gedit /var/lib/dpkg/alternatives/x-www-browser
The output will be like this:
auto
/usr/bin/x-www-browser
/usr/bin/firefox
40
/usr/bin/google-chrome-stable
200
/usr/bin/vivaldi-stable
200
Now easily change the priority of chrome (200) by whatever you want then save. (I changed to 50)
check the new settings
update-alternatives --query x-www-browser
