No installation candidate for "libicu52" on 15.10

Install libicu55 instead:

sudo apt-get install -y libicu55

You can also search for this package:

sudo apt-get update
apt-cache search libicu

If the latter command gives you some results (eg. libicu with version number other than 52) you can check if installing it suits your needs.

you can download deb package from

https://launchpad.net/ubuntu/wily/+package/libicu52

works for me.

Try:

wget http://mirrors.kernel.org/ubuntu/pool/main/i/icu/libicu52_52.1-3ubuntu0.8_amd64.deb
dpkg -i libicu52*.deb

Found the solution here. So download the .deb package and install manually by:

sudo dpkg -i libicu52_52.1-3ubuntu0.8_amd64.deb

See: http://packages.ubuntu.com/en/trusty/libicu52`

Just ran into this today. I fixed it by adding the microsoft packages to my apt-get sources like so:

sudo add-apt-repository "deb [arch=amd64] https://packages.microsoft.com/ubuntu/16.04/prod xenial main"

Then:

sudo apt-get update

And then libicu52 installed.

Found here.
