Description of problem: not sure whether bug or feature to mitigate dataloss in doubtful situations. @f17 running virt-install. requested system is serial console minimal f19. it's possible to ctrl+c sigint the installation process. result is several pages of errors, screen redraws and such. below is the [ OK ] Reached target Paths. Starting installer, one moment... ^CTraceback (most recent call last): File "/sbin/anaconda", line 677, in <module> from pyanaconda import geoloc import timezone File "/usr/lib64/python2.7/site-packages/pyanaconda/timezone.py", line 31, in <module> from pyanaconda import localization File "/usr/lib64/python2.7/site-packages/pyanaconda/localization.py", line 32, in <module> import langtable File "/usr/lib/python2.7/site-packages/langtable.py", line 1124, in <module> __module_init = __ModuleInitializer() File "/usr/lib/python2.7/site-packages/langtable.py", line 1118, in __init__ _init() File "/usr/lib/python2.7/site-packages/langtable.py", line 1113, in _init _read_file(datadir, 'languages.xml', LanguagesContentHandler()) File "/usr/lib/python2.7/site-packages/langtable.py", line 626, in _read_file _expat_parse(file, sax_handler) File "/usr/lib/python2.7/site-packages/langtable.py", line 608, in _expat_parse parser.ParseFile(file) File "/usr/lib/python2.7/site-packages/langtable.py", line 127, in characters if self._save_to is None: KeyboardInterrupt Pane is dead if self._save_to is None: KeyboardInterrupt Pane is dead [anaconda] 1:main* 2:shell 3:log 4:storage-log 5:program-log
Created attachment 779159 [details] screenshot showing KeyboardInterrupt after pressing ctrl-C during installer startup in text mode Confirmed. The response to ctrl-C is inconsistent -- sometimes it is ignored, sometimes it generates a "Pane is dead" with no traceback, sometimes it generates a "Pane is dead" with a traceback, all depending on where in the install process ctrl-C is pressed. What is the expected behavior? Tested by entering "text" on the kernel command line with: $ qemu-kvm -m 4096 -hda f19-test-2.img -cdrom ~/xfr/fedora/F19/Fedora-19-x86_64-DVD.iso -vga std -boot menu=on
This very well may be a bug, but ctrl-c behavior is definitely not high up on our priority list. anaconda is kind of a special process - you can just reboot if you want. We do not have any formalized behavior for this, and I can't really see getting to it.
