QGIS – Fixing Incorrect Scale Bar in Print Composer
print-composerqgisscale bar
Adding a scale bar to my layout shows an incorrect scale (see image).
I am using EPSG:2097. What do I need to do to make the scale bar show the correct scale?

While working in QGIS' Layout Manager, you want to make sure that the scale bar is referred to a specific map which in turn needs to be in a projected CRS (from the Map drop-down menu):
That is because if CRS of the project is a Geographic one (i.e. Lat/Long), the scale bar is showing degrees, even if the label was forced to show 'm' for meters through the Scalebar units drop-down.
If you want a scale bar with lengths in actual meters/km/feet, change the project's CRS to a projected one (like UTM, for example).
From the menu Project -> Properties -> CRS tab
Lastly, make sure that in Layout Manager, the map referred to by the Scale bar object shows a projected CRS:
