How to fix this apt mess?

Question

I'm using PureOS, which is basically Debian with some small tweaks. I tried installing firefox on it, but ended with a complete mess. If I now try to do a basic upgrade, I get this:

$ sudo apt update && sudo apt upgrade

I've tried to remove firefox in many ways:

$ sudo apt -y remove firefox
[sudo] password for hielke:

Package 'firefox' is not installed, so not removed

The following packages have unmet dependencies:
 iceweasel : Depends: firefox-esr but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

I've also tried the following variations, but all gave similar results:

sudo apt remove firefox
sudo apt purge firefox
sudo apt remove firefox-esr
sudo apt purge firefox-esr
sudo apt remove iceweasel
sudo apt purge iceweasel
sudo apt remove purebrowser
sudo apt purge purebrowser

[EDIT 2]

Following the answer by @alan I tried removing the diversion:

$ sudo dpkg-divert --remove /usr/bin/firefox
Removing 'diversion of /usr/bin/firefox to /usr/bin/firefox.real by purebrowser'

After that I did an update and then an upgrade:

The following packages have unmet dependencies:

E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

Unfortunately the same result as you can see. I tried apt --fix-broken install just to be sure, but that gave the same result as before.

So I used the command to find other diversions (although I'm not 100% sure what diversions are exactly):

& sudo dpkg-divert --list | grep firefox
diversion of /usr/share/applications/firefox-esr.desktop to /usr/share/applications/firefox-esr.desktop.diverted by xul-ext-iceweasel-branding

So I just filled in what I thought was right:

$ sudo dpkg-divert --remove /usr/share/applications/firefox-esr.desktop
Removing 'diversion of /usr/share/applications/firefox-esr.desktop to /usr/share/applications/firefox-esr.desktop.diverted by xul-ext-iceweasel-branding'

but again I get the same:

Any more tips?

[EDIT 3]

Following the tips from @harrymc I tried running this:

$ sudo apt-get install iceweasel
[sudo] password for hielke: 
Reading package lists... Done
Building dependency tree       
Reading state information... Done
iceweasel is already the newest version (52.6.0esr-1~deb9u1).
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 iceweasel : Depends: firefox-esr but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

As you can see that didn't do the trick. So here's the output apt-cache policy firefox-esr:

$ apt-cache policy firefox-esr
firefox-esr:
  Installed: (none)
  Candidate: 52.6.0esr-1~deb9u1
  Version table:
     52.6.0esr-1~deb9u1 500

     52.5.0esr-1~deb9u1 500
        500 http://deb.debian.org/debian stretch/main amd64 Packages

Just for info, here are the contents of my /etc/apt/sources.list:

Does this tell you anything?

Have you tried removing the broken Firefox installation? `sudo apt -y remove ` — Prav, Feb 09 '18 at 22:56
@PraveenP - yes I did. I added that to the question. Any other ideas? — kramer65, Feb 11 '18 at 17:05
Following EDIT 2: Try to run this command : `sudo apt-get install iceweasel`. If this doesn't help, please provide the output of `apt-cache policy firefox-esr`. And which repository are you using with apt? — harrymc, Feb 12 '18 at 20:30
@harrymc - Thanks for the tip. Unfortunately that doesn't do it yet. I've added the results to the question under [EDIT 3]. Does that tell you anything? — kramer65, Feb 12 '18 at 22:10
Following EDIT 3: Iceweasel might be the problem, as it is a rebranded version of Firefox, but discontinued now. Try `apt-get remove iceweasel`. — harrymc, Feb 13 '18 at 07:30
@harrymc - I tried variations of that already (and again now) but that doesn't make any difference. — kramer65, Feb 13 '18 at 08:52
@kramer65 When you get a chance, can you hop into [chat](https://chat.stackexchange.com/rooms/118/root-access)? I'd like to try some more interactive troubleshooting. — Bob, Feb 13 '18 at 12:55
Give it a look if it is the case to clean _manually_ the temporary download/cache/packages... and to start to install firefox again. [Self-citation](https://askubuntu.com/a/498949/196535). Note that `apt` and `apt-get` may work in a different way and that `apt-get` has two different options `-m` and `-f`, sadly [another self-citation](https://askubuntu.com/a/462751/196535) `:-)`. — Hastur, Feb 15 '18 at 12:49

Firefox is trying to create a diversion, when a diversion with that name already exists.

You need to remove the existing diversion first.

This is the error line:

dpkg-divert: error: 'diversion of /usr/bin/firefox to /usr/bin/firefox.real by firefox-esr' clashes with 'diversion of /usr/bin/firefox to /usr/bin/firefox.real by purebrowser'

From this solution:

sudo dpkg-divert --remove /usr/bin/firefox

Note: if the diversion is not caused by /usr/bin/firefox, you may need to identify the diversion with either sudo dpkg-divert --list | grep firefox or sudo dpkg-divert --list | grep purebrowser On a side note, if you don't like the locale error message thrown by Perl, you can get rid of it by exporting your locale, as shown here:

export LC_CTYPE=en_US.UTF-8
export LC_ALL=en_US.UTF-8

If all else fails, open up the package record and remove iceweasel by hand:

sudo -i gedit /var/lib/dpkg/status

(you'll probably see a block that starts something like Package: Iceweasel Status: Install broken). See this similar issue: Unable to fix broken packages with sudo apt-get install -f

Hi Alan. Thanks for your suggestions. I tried them but I didn't get to a solution. I described it in the question under `[EDIT 2]`. Do you have any other ideas? – kramer65 Feb 12 '18 at 16:47
A diversion is an instruction to install a file etc. from a package with a different name than it would normally be installed (e.g. firefox -> firefox.desktop). To remove the diversion you need to remove the source, not the result. Try: `sudo dpkg-divert --remove /usr/share/applications/firefox-esr/xul-ext-iceweasel-branding` – Alan Feb 13 '18 at 00:11
I tried your suggestion, but then I get `No diversion 'any diversion of /usr/share/applications/firefox-esr/xul-ext-iceweasel-branding', none removed.` – kramer65 Feb 13 '18 at 07:37
I know you've tried removing the browsers, but have you tried removing the branding package? It's long shot but removing them in order (apt purge) and reinstalling just the appropriate package. Looks like the order is xul-ext-iceweasel-branding->iceweasel->firefox. You shouldn't need iceweasel or firefox as PureOS provides PureBrowser. – Alan Feb 13 '18 at 21:11

If all else fails, open up the package record and remove iceweasel by hand: **sudo -i gedit /var/lib/dpkg/status** (you'll probably see a block that starts something like Package: Iceweasel Status: Install broken).

Use this: sudo dpkg -i --force-all /var/cache/apt/archives/firefox-esr_52.6.0esr-1~deb9u1_amd64.deb and you will force-install firefox-esr. 99.9% it'll fix your problem. Then follow it up with sudo dpkg --configure -a and you'll most probaly be in the clear.

As a general rule, when mixing stuff in installations you'll find a package that needs to overwrite a file from another package. Using dpkg with the --force-all option in these cases lets you play God, but it also overrules all those nice security checks built in in Debian's package management system. But after all, that's one of the burdens of being the root user.

When you look at the repos the Debian includes the 'Iceweasel' package while the PureOS repo contains the firefox-esr package. Based on the error messages they are conflicting.

This might remove your Firefox profile but I would try:

sudo apt purge firefox firefox-esr iceweasel purebrowser
sudo apt install firefox-esr

That should install the firefox package from the PureOS repo.

Iceweasel was a rebrand of Firefox done by Debian but they are reverting their changes. In Debian stretch it's still called Iceweasel but it simply installs a patched firefox-esr, in the next Debian version it should simply be called firefox-esr.

Is it possible you added those debian repos yourself? That's never a good idea to mix distro repositories. Comment those lines out then:

apt clean && apt update

Then try again to purge & install.

Thanks, but as you can read in the question I've tried removing all related browsers (firefox, firefox-esr, iceweasel and purebrowser) using both `apt remove` and `apt purge`. But that gives me some output, ending in the error `E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).` Any ideas how I can overcome that error? – kramer65 Feb 13 '18 at 12:46
I completely missed that you tried that already...Can you try purging them all in one command like I updated? – HoD Feb 13 '18 at 14:02
I edited again asking about the Debian repos, seems fishy now that I think about it. – HoD Feb 13 '18 at 14:24

The firefox packages in the PureOS might be inconsistent or in a state of transition.

In this case, I suggest to remove the packages of iceweasel, firefox and firefox-esr (or all other variants of firefox), then download and install the latest Linux build of Firefox directly from Mozilla.
To terminate, check that automatic updates are enabled.

For more information see the Mozilla article Installing Firefox - Linux.

To remove a broken package, you may use the nuclear option of :

sudo dpkg --remove --force-remove-reinstreq package_name

If it gives you an error that it won't remove a package because it is depended on by another package, remove that other package as well.

Does the latest Linux build of Firefox from Mozilla work even if you don't remove these broken packages? – harrymc Feb 13 '18 at 13:06
You may also try `sudo dpkg --remove --force-remove-reinstreq package_name`. If it gives you an error that it won't remove a package because it is depended on by another package, remove that other package as well. – harrymc Feb 13 '18 at 14:29
