With a bit of bad luck tl-setup (and likely the installer) can crash if you resize the terminal where you run it. The problem is that this sends a SIGWINCH which in turn can abort system calls with EINTR. This can happen anywhere in the code where a system call is used, but in my case I got: > 2021-05-04 14:38:36,687: Traceback (most recent call last): > 2021-05-04 14:38:36,688: File "/opt/thinlinc/sbin/../libexec/tl-setup.py", line 315, in <module> > 2021-05-04 14:38:36,688: Oo0O0OOOoo ( ) > 2021-05-04 14:38:36,688: File "/opt/thinlinc/sbin/../libexec/tl-setup.py", line 268, in Oo0O0OOOoo > 2021-05-04 14:38:36,688: o00oooO0Oo = o0O00o . run ( ) > 2021-05-04 14:38:36,688: File "/opt/thinlinc/modules/thinlinc/wizard.py", line 100, in run > 2021-05-04 14:38:36,688: return self . _run_text ( ) > 2021-05-04 14:38:36,688: File "/opt/thinlinc/modules/thinlinc/wizard.py", line 118, in _run_text > 2021-05-04 14:38:36,688: oOOO00o ( ) > 2021-05-04 14:38:36,688: File "/opt/thinlinc/modules/thinlinc/tlsetup/gtk.py", line 81, in <lambda> > 2021-05-04 14:38:36,688: IiIiI11iIi ) > 2021-05-04 14:38:36,688: File "/opt/thinlinc/modules/thinlinc/tlsetup/pkginsthelp.py", line 75, in generic_text_installer > 2021-05-04 14:38:36,689: i1Ii = iiIIi1IiIi11 . run ( ) > 2021-05-04 14:38:36,689: File "/opt/thinlinc/modules/thinlinc/tlsetup/pkginsthelp.py", line 482, in run > 2021-05-04 14:38:36,689: o0oOO000oO0oo = self . __backend . install ( ) > 2021-05-04 14:38:36,689: File "/opt/thinlinc/modules/thinlinc/packageinstaller/dnfbackend.py", line 67, in install > 2021-05-04 14:38:36,689: callback = self . _dnf_callback ) > 2021-05-04 14:38:36,689: File "/opt/thinlinc/modules/thinlinc/packageinstaller/dnfbackend.py", line 121, in iIiiiI > 2021-05-04 14:38:36,689: ( I11II1i , IIIII , ooooooO0oo ) = select . select ( [ oOOO00o . stdout , oOOO00o . stderr ] , [ ] , [ ] ) > 2021-05-04 14:38:36,689: error: (4, 'Interrupted system call') Fixing this is a pain unfortunately as it means doing this annoying construct around all system calls: > while True: > try: > call() > except OSError as e: > if e.errno == errno.EINTR: > continue > else: > raise Fortunately upstream Python has apparently realized what an unmaintainable mess this is: https://www.python.org/dev/peps/pep-0475/ TL;DR; It's fixed in Python 3.5 If we want to fix this for earlier versions we'll need to start adding wrappers. A middle ground could be to only add wrappers for long running system calls such as select().
