warning ! Fix Blogger mobile version m=0,m=1 Duplicate meta descriptions

Blogger mobile m=0,m=1 Duplicate meta descriptions
Today during a routine checking for my blog in web master tools i mentioned that there is a  "Duplicate meta descriptions" error so i checked the cause of this error and found duplicated links like

/2013/03/Blogger-blogroll-widget-screenshot-thumbnails.html
/2013/03/Blogger-blogroll-widget-screenshot-thumbnails.html?m=0
/2013/03/Blogger-blogroll-widget-screenshot-thumbnails.html?m=1
since m=1 and m=0 are the cause of error this means that mobile version for my blog is causing  a  duplicate description problem that massively impact blogs . So how can we solve this issue ?

Adding canonical rel links to header  didn`t solve the problem , i believe that blogger adds a canonical tag automatically yet adding canonical rel tag didn`t solve the problem too

turning off mobile version didn`t solve the problem i just turned the mobile version css off but the mobile version was still in act

The only way that could bulk solve this problem is using  robot.txt 

Go to Blogger dashboard > search preferences > Custom robots.txt > Enable custom robots.txt content
