sakshisinha, hi and to BC (Bleeping Computer) and to the Linux side of the equation!
Albeit, a rocky start by the looks of things.
Screenshots will help. You can read Moderator Stolen's post at this Topic, and/or read NickAu's pinned Topic on the front page of the Linux and Unix forum. You will need an image hosting site, as you will see on reading.
When you ask for support you should also include as much information about the problem as possible. Including all of the important details in your first post will greatly speed up the entire support process and allow our volunteers to better assist you. While you may think a particular error message isn't very helpful, it may be the key to resolving your issue. Some details we are looking for would include, but not be limited to:
- Your distribution's name (Mint, Ubuntu, Debian, etc), version (17, 14.04, 7, etc), and architecture (32-bit, 64-bit).
- Provide relevant information about your physical hardware or installed software.
- Share relevant log files, screenshots, detailed error messages, or anything else that could be used to troubleshoot your issue.
The above is from Kaosu's excellent article, also pinned near Nick's, about properly giving and receiving support, well worth the read, IMO (In My Opinion).
If you take a look at my Profile via my avatar (picture) and read my signature below, you will see some of the information we can use to better help you.
