I was replacing Network Manager with Wicd and restarted the computer and now after the login screen I get

"Unable to launch "cinnamon-session-cinnamon" X session "cinnamon-session-cinnamon" -found; Falling back to default "session."

I can exit the prompt and then I get a black screen, then if I press CTRL-ALT F1 it takes me to a login terminal and then I have an open terminal, is there a way to reinstall cinnamon from there so I don't lose all the work I've done?

I used the command "sudo apt-get purge network-manager" after installing Wicd and I saw "removing cinnamon" but didn't realize it would do this. I think the right command was "sudo apt-get remove network-manager"

There would have been no difference between a purge and a remove. Those packages dependent on the network manager would have been removed in either case. It's always useful to read warning messages carefully before proceeding.

You don't say which version of Mint you are using, but if you have TimeShift installed and running then you should be able to simply revert to a previous snapshot before you carried out the removal of network-manager. Is this the case?

Does anyone have a solution for this? I have the same exact issue due to replacing the network manager with Wicd . I’m using Linux mint 18.3 Sylvia.

I also have the same proble. Please anyone help ASAP.

it looks like cinnamon is dependent on network-manager
so

should get it back ( along with network-manager )

the problem occurs after using the command "sudo apt-get purge network-manager" after installing Wicd. So i cannot connect to internet access to install any software. I would like to request you to let me know where should i get to download the cinnmon package. As my same laptop has dual system, so i can download the cinnamon package on harddrive and try to install offline.

Thanks in advance.

download network-manager and install that, it will be quicker

I can't tell you where to d/l it from as I have no idea what disto you are using.
you will need the package for your version

From where I could download network-manager package..? I had tried to install it by downloading from gnome project site. But it does not work.

what disto?
what version?

how do you normally connect to the internet>
is it through a wire or over wifi?

we can *maybe* connect to network manually

here I attach a photo. Please check it.

just type it

Name= linux mint
Version= 19.2(tina)
Id= linuxmint
Id_like= ubuntu
Pretty_name= linux mint 19.2
Version_id= 19.2
Version_codename= Tina
Ubuntu_codename= bionic

4.15.0-58 generic

Normally I connect to the internet through wifi. But here the things is different. Here I can access only terminal by ctrl+alt+f1. So I think the only way to install any package is to download it from different OS and then copy/paste on this hard disk, after that install it offline.

ok
First try

that assumes you are on a wire

now we will try to install network-manager ( and hope you have internet)
did that work?
