I'm on Peppermint 5 and decided to get Chrome to replace Chromium. The browser wouldn't launch so I decided to update the software  from the update manager. After the updates, I no longer see the Network Manager, so I cannot connect to the internet via wifi. I plugged in  the ethernet cable but nothing as well. What is the best place to start? I'm thinking I need to update or re-install something, but how do I do this without any internet?

What happens if you run:
Code: [Select]
nm-applet &
does the network manager panel applet start ?

If not, what happens if you run:
Code: [Select]
nm-connection-editor
?

If nothing, what is the output from:
Code: [Select]
dpkg -l | grep network-manager
?

Download these 2 files to another PC, then move them over to the Peppermint 5 PC via a USB stick

http://security.ubuntu.com/ubuntu/pool/main/n/network-manager/network-manager_0.9.8.8-0ubuntu7.1_amd64.deb
and
http://security.ubuntu.com/ubuntu/pool/main/n/network-manager-applet/network-manager-gnome_0.9.8.8-0ubuntu4.5_amd64.deb

then double-click them one at a time (in the order above) to install them.

Once installed, reboot.

Trying to install the first package and I get a message saying "Broken dependencies".It suggests to run 'gksudo synaptic'or 'sudo apt-get install -f'in a terminal window.

I got the same message from the second package too.

I don't recall it specifying which dependency, but it went through the installation and then said it failed.  When I try to run it again, it shows the broken dependency error without trying to go through the installation, so I can't replicate what it said the first time.

Hmm...

What happens if you remove oracle-java8-set-default
Code: [Select]
sudo apt-get remove oracle-java8-set-default
THEN try installing network-manager and network-manager-gnome

Then I re-ran network-manager_0.9.8.8-0ubuntu7.1_amd64.deb, but it has the same message as before. So a popup window called gdebl-gtk with the message "Failed to completely install all dependencies
To fix this run 'sudo apt-get install -f' in a terminal window"

Then I closed that window and in the installation window I see it say Package: network-manager
Status: Error: Failed to satisfy all dependencies (broken cache).

If I run it again, I get the broken dependency error from before as well.

Thanks for helping out during Christmas Eve (and likely Christmas...).

This is the result of the purge remove

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 libnl-3-200 : Breaks: network-manager (< 0.9.8.8-0ubuntu7.3~) but 0.9.8.8-0ubuntu7.1 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

[close]

Still get the dependency error when trying to install network-manager again.

Okay delete those 2 files I had you download earlier...

Then download these versions instead
http://cz.archive.ubuntu.com/ubuntu/pool/main/n/network-manager/network-manager_0.9.8.8-0ubuntu7.3_amd64.deb
and
http://cz.archive.ubuntu.com/ubuntu/pool/main/n/network-manager-applet/network-manager-gnome_0.9.8.8-0ubuntu4.5_amd64.deb

Copy those the the broken PC, and try installing them (in the order above).

Didn't work. Same thing before where a popup window called gdebl-gtk with the message "Failed to completely install all dependencies
To fix this run 'sudo apt-get install -f' in a terminal window".

I see something on the taskbar with a giant red x. It says n error occured, please run Package Manager from the right-click menu or apt-get in a terminal to see what is wrong. The error message was: rror: BrokenCount > 0'. This usually means that your installed packages have unmet dependencies.

I opened Package Manager and went to Broken dependencies. I see package libnl-3-200 as the package. Should I remove this first?
