Cross-posted to 2 groups.

Package: linux-perf-4.19
Version: 4.19.67-2+deb10u2
Severity: normal
Tags: upstream

perf embeds a python interpreter and the debian linux source package has
debian/rules.d/tools/perf/Makefile:MAKE_PERF += PYTHON=/usr/bin/python3

However, many of the scripts in tools/perf/scripts/python, executed via `perf
script [...]`, did not support python3 in the 4.19 release.

For example:
root@vdebian:~# perf script net_dropmonitor
  File "/usr/lib/perf_4.19-core/scripts/python/net_dropmonitor.py", line 53
    print "%25s %25s %25s" % ("LOCATION", "OFFSET", "COUNT")
                         ^
SyntaxError: invalid syntax
Error running python script /usr/lib/perf_4.19-core/scripts/python/net_dropmonitor.py
