+debhelper (13.3.4ubuntu2) impish; urgency=medium
+
+  * objcopy/strip changed in 2.36.1, not keeping file attributes of the
+    original file. Work around that in dh_strip to write to a temporary
+    file, copying attributes, cat'ing this to the original file, copying
+    attributes again to keep the original attributes. LP: #1938886
