I downloaded the Upwork desktop App on ubuntu 18.04. When I open it with Gdebi package installer I saw this error:

I tried to install gksu manually via sudo apt install gksu but I got this error

Building dependency tree       

Reading state information... Done

Package gksu is not available, but is referred to by another package.

This may mean that the package is missing, has been obsoleted, or

is only available from another source



E: Package 'gksu' has no installation candidate

How can I install this software on ubuntu 18.04 (I download it yesturday so it is the most recent version on upwork website) ?

Today, gksu was removed from Ubuntu 18.04, four weeks after it was removed from Debian.

So theoretically speaking there are no packages on Bionic Beaver 18.04 LTS, depending on gksu. But this is not true:

$ apt-cache rdepends gksu

gksu

Reverse Depends:

  gexec

  wicd-gtk

  spacefm-gtk3

  spacefm

 |menu



$ aptitude why gksu 

i   menu Suggests gksu | kde-runtime | ktsuss

As you see some software, which are distibuted by third-party may depend on gksu package. So you can proceed installing gksu with method below on your own risk.

How to fix?

Possible solution is to install version from previous (17.10, artful) release.

Warning: do not execute the commands below if unsure!

Short method (as @MK suggested)

wget http://archive.ubuntu.com/ubuntu/pool/main/libg/libgtop2/libgtop-2.0-10_2.32.0-1_amd64.deb

sudo apt install ./libgtop-2.0-10_2.32.0-1_amd64.deb



wget http://archive.ubuntu.com/ubuntu/pool/universe/libg/libgksu/libgksu2-0_2.0.13~pre1-6ubuntu8_amd64.deb

sudo apt install ./libgksu2-0_2.0.13~pre1-6ubuntu8_amd64.deb



wget http://archive.ubuntu.com/ubuntu/pool/universe/g/gksu/gksu_2.0.2-9ubuntu1_amd64.deb

sudo apt install ./gksu_2.0.2-9ubuntu1_amd64.deb

Test

Test gksu (should work on Xorg-sessions)

gksu-properties # check that it has "Authentication mode" to "sudo"

gksu date

gksudo date

Notes

After installation the following packages will be marked as obsolete (locally-installed): gksu, libgksu2-0. But they will work as expected.
