Ok, so that’s what I was looking for and seeing it means that you should be able to select Firefox from the menu. However, considering everything else we have done, you might have to restart your machine to see if that works.
Thanks. It will have to wait until tomorrow.
Erich, since the Firefox .deb package wouldn’t be required anymore, couldn’t Alan just remove that Firefox .deb package completely, restart the machine, then select the snap browser as default? I would have thought, given that scenario, there would not have been any need for re-install of the snap.
Is that not so?
It could be removed, but it sets itself as providing x-www-browser which is something the snap cannot do on its own. I wanted to make sure the package was there so that virtual package could be provided, otherwise other browsers could, theoretically, take over as default not seeing something else installed as that virtual package.
I’ll admit, it’s a shot in the dark. And no, the .deb will not be removed anytime soon from the repositories, if at all.

I’m sorry, Erich, but I am a bit confused.
I thought you said that package was only needed during install, and not required after install.
Did I mis-interpret?
It can be safely removed, not required after install. I’m sorry I confused. I’d keep it around to be safe, though.

I have restart the PC, Firefox has updated to 143.0.3 but it still doesn’t show as default in Setttings.
I ran wireless.info which sends results to the default browser, just to check, but that doesn’t happen and the txt file says “last command not found”, so definitely no default present or accessible.
How exactly do you run it ? From a terminal ? By clicking on it in a file manager ?
Looking at the code the wireless info script does not launch any browser at all but displays a dialog with a pastebin URL to click on (or the pastebin URL in a terminal when no kdialog or zenity is installed) …
I would recommend that @portalan actually runs:
sudo apt update
sudo apt full-upgrade
(or sudo apt dist-upgrade)
Not upgrade.
Also, try sudo apt install lubuntu-desktop^.
These two steps will replace any missing packages that may have been erroneously uninstalled, or erroneously not installed.
Ogra,
from a terminal:
./wireless-info
[sudo] password for alant:
Results saved in "/home/alant/wireless-info.txt".
Do you also want to post them to your default 'pastebinit' provider? [Y/n]: Y
Pastebin failed, error message is:
Failed to contact the server: HTTP Error 400: Bad Request
That might just be an issue with paste.ubuntu.com for now
The script just tries to upload the text file to a paste site
Popey,
I have done:
sudo apt update
sudo apt full-upgrade
sudo apt install lubuntu-desktop^
The last one created a long list, with no apparent issues.
Settings still shows Firefox is not the default.
Feel free to paste that entire file here between two sets of three backticks ( `, the key above tab or the ~ key without the shift).
```
LIke so
```
Like so
It will automatically create scrollbars if needed.
Here goes:

Yes. (. . . . . . . . )

The file that appears in Featherpad is empty. Am I looking in the wrong place?
