[root@impairment1 scripts]# ./ovs-check-dead-ifs
File "./ovs-check-dead-ifs", line 40
print "%s: unexpected format\n" % fn
^
SyntaxError: Missing parentheses in call to 'print'. Did you mean print("%s: unexpected format\n" % fn)?

Description of problem: ----------------------------------------------------------------------------------- Error message would be observed if execute ovs-check-dead-ifs in Red Hat Enterprise Linux 8 ----------------------------------------------------------------------------------- Version-Release number of selected component (if applicable): ----------------------------------------------------------------------------------- # cat /etc/redhat-release Red Hat Enterprise Linux release 8.0 (Ootpa) # uname -a Linux haclustern2 4.18.0-80.11.1.el8_0.x86_64 #1 SMP Tue Sep 3 11:21:25 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux openvswitch2.11-2.11.0-18.el8fdp.x86_64 ----------------------------------------------------------------------------------- How reproducible: ----------------------------------------------------------------------------------- execute the file via /usr/share/openvswitch/scripts # ovs-check-dead-ifs File "/usr/share/openvswitch/scripts/ovs-check-dead-ifs", line 40 print "%s: unexpected format\n" % fn ^ SyntaxError: Missing parentheses in call to 'print'. Did you mean print("%s: unexpected format\n" % fn)? ----------------------------------------------------------------------------------- Steps to Reproduce: ----------------------------------------------------------------------------------- 1. execute the file via /usr/share/openvswitch/scripts ----------------------------------------------------------------------------------- Actual results: ----------------------------------------------------------------------------------- File "/usr/share/openvswitch/scripts/ovs-check-dead-ifs", line 40 print "%s: unexpected format\n" % fn ^ SyntaxError: Missing parentheses in call to 'print'. Did you mean print("%s: unexpected format\n" % fn)? ----------------------------------------------------------------------------------- Expected results: ----------------------------------------------------------------------------------- no error should be observed ----------------------------------------------------------------------------------- Additional info: ----------------------------------------------------------------------------------- ovs-check-dead-ifs is developed by python and would follow python 2.x syntax. However, by default, Red Hat Enterprise Linux 8 uses python3. The print call is different in python2.x and python3. So when ovs-check-dead-ifs executes in Red Hat Enterprise Linux 8, error message can be observed. We should modify the python code for ovs-check-dead-ifs 1. Line 40, update from 'print "%s: unexpected format\n" % fn' to 'print ("%s: unexpected format\n" % fn)'' 2. Line 100 update from ' print """ The following processes are listening for packets to arrive on network devices that no longer exist. You may want to restart them."""'' to 'print (""" The following processes are listening for packets to arrive on network devices that no longer exist. You may want to restart them.""")' -----------------------------------------------------------------------------------
