In order to install Pulse Secure client, I need to install libcurl4 on my ubuntu16.04. but it reports error:
~/Downloads$ sudo apt install libcurl4
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package libcurl4 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 'libcurl4' has no installation candidate
I know there are other versions of libcurl4 (such as libcurl4-openssl-dev) and I tried to install it successfully. But I found that this did not work. So I still need to install the "libcurl4" on my ubuntu. I used the update command several times but it did not work.
I searched online but didn't find answers to my question. I found that others used the same commands as mine and they succeed in the installation, but I did not know why. Could anyone help me about this? Thanks in advance.
