Description Karl Mikaelsson cendio 2017-12-15 11:07:29 CET 
ThinLinc 4.5.0
SLES12 SP3 (x86_64)

Noticed this while upgrading from ThinLinc 4.4.0. I used tl-setup with an answer file.

This happened only once. I was not able to reproduce the problem by re-running tl-setup.

This is an old ThinLinc version, but we haven't upgraded our copy of subprocess.py since then so it is likely the problem remains.
Comment 2 Peter Åstrand cendio 2017-12-19 15:14:43 CET 
Upstream bug, fixed in subprocess.py shipped with Python 2.7:

Comment 3 Pierre Ossman cendio 2018-10-16 14:09:54 CEST 
Bug 4120 has been fixed now and we are now using the system version of subprocess. As such, we consider this an issue for the distribution to fix and not us.

(most distributions will also be running a new enough python to have this fixed)
