Edebhelper-compat-file-contains-multiple-levels
The tag is present in Lintian version 2.104.244. That is the most recent version we know about.
The debian/compat file appears to contain multiple
compatibility levels.
This was likely due to the use of >> instead of > when updating the level.
Please update the file to specify a single level.
Refer to the debhelper(7) manual page for details.
