E:Malformed line 61 in source list /etc/apt/sources.list (dist parse)

The problem could not be reproduced. The reporter, amit ate, was requested to provide the information of his sources.list in order to correct the problem. We believe this is not a bug but an issue that needs only technical support therefore we are converting this to a question.

Hi amit ate, the 61st line in your /etc/apt/sources.list probably contains an invalid link or incorrectly typed URL. Please check the file and post the result here in order for us to resolve.

Thank you!

This issue seems to be old already and I assume that it has already been corrected. If it is, kindly mark this as SOLVED or CLOSED.

Thank you again!
