@Manisha: were you installing the chromium snap at the same time as you were installing chromium-browser, by any chance?

An user called chirag patel solves the problem and posted it on Medium: https://medium.com/@chiragpatel_52497/unable-to-install-package-name-snap-package-name-has-install-snap-change-in-progress-b6768f2ce81d

This solves the problem:

Snap is probably still working on something in the background (or at least it thinks so). Open a terminal and run snap changes so see a list of ongoing changes.

$ snap changes ... 123 Doing 2018-04-28T10:40:11Z - Install "foo" snap ...

You can abort ongoing change(s):

$ sudo snap abort 123

Then you should be able to successfully install chromium-brownser through the software center.
