How can I install these two packages on latest PureOS

I have a problem with the following packages - how can I install the offending packages??

sherab@Sherab-13v4:~$     sudo apt-get install -y mono-complete xdotool libappindicator0.1-cil-dev
Reading package lists... Done

E: Couldn't find any package by regex 'libappindicator0.1-cil-dev'

libappindicator0.1-cil-dev is an ancient package from Jessie. When did you buy your machine? Maybe you should upgrade.

Can you post the contents of your /etc/apt/sources.list file?

just copy-paste into terminal

sudo cat /etc/apt/sources.list

then enter and type admin password then copy and paste back here what the output is …

ok I posted it in a message below

@sherab_kelsang, I don’t see it.

Not sure if this helps @amosbatto, but I’ve just tested abbreviated version (easier one) of above posted install command:
sudo apt update
sudo apt install mono-complete (
Do you want to continue? [Y/n]

Therefore I doubt that anything related to current mono-complete package is missing within PureOS repo, yet:
sudo apt dist-upgrade --fix-missing

P.S. Another, if someone insists, approach might be on how to use repository with PureOS, but I believe (somehow) this is out of the subject here.

@amosbatto @reC
Here it is -

# deb  jessie main
# deb-src  jessie main

deb amber main
deb amber-security main
deb amber-updates main

sudo apt update
sudo apt full-upgrade

That should get rid of all your Jessie packages. Then you should be able to install what you want.

‘jessie’ is OLD. any reason in particular you keep it ?

I actually added it because it was in the installation guide in the packet I was trying to install.
I’m trying to install RemoteMouse for Linux.
