Aborting tailf causes bash session to be corrupted

This document (000019885) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Enterprise Server 12 SP5
SUSE Enterprise Server 12 SP4

Situation

When running a tailf and stop this with <ctrl><c> the bash console is broken. Characters being typed are not displayed and the prompt is displayed after each other when pressing enter. Only a reset brings the console back.
The file /etc/bash_completion.d/python-argcomplete exists.
In some cases the same issues have been seen when an echo (e.g. in a script) is stopped with <ctrl><c>.
The issue is often seen on Azure when the following package is installed:
  • azure-cli-2.0.81-4.1

Resolution

Engineering is looking if the fix can be backported to bash version 4.3.

Cause

This is a known issue in bash version 4.3 available on SUSE Enterprise Server 12 SP4 and SP5.
The issue is described in the following github issue.
The issue is not present in bash version 4.4 used on SUSE Enterprise Server 15.
 

Status

Reported to Engineering

Additional Information

Removing the file /etc/bash_completion.d/python-argcomplete could be a workaround, but it has to be tested, if it causes no other problems.
