We will get a traceback about unhandled 'KeyboardInterrupt' if SIGINT (Ctrl-C) is sent during the package resolving step. I found this on 4.12.0 and on jenkins build 2108 on Fedora 33 using GUI mode. To reproduce this, send a SIGINT during the step "Library and binary requirements - Resolving dependencies" of tl-setup in GUI mode. The traceback we will get: >2021-06-02 13:22:39,568: AppArmor disabled or not present >2021-06-02 13:22:39,568: System checks done. >2021-06-02 13:22:45,692: Resolving packages... >2021-06-02 13:22:47,224: tl-setup aborted by user >2021-06-02 13:22:47,415: Traceback (most recent call last): >2021-06-02 13:22:47,415: File "/opt/thinlinc/libexec/dnfhelper", line 214, in <module> >2021-06-02 13:22:47,415: main() >2021-06-02 13:22:47,415: File "/opt/thinlinc/libexec/dnfhelper", line 205, in main >2021-06-02 13:22:47,416: do_resolve(sys.argv[2:]) >2021-06-02 13:22:47,416: File "/opt/thinlinc/libexec/dnfhelper", line 69, in do_resolve >2021-06-02 13:22:47,416: _prepare_transaction(base, pkgs) >2021-06-02 13:22:47,416: File "/opt/thinlinc/libexec/dnfhelper", line 46, in _prepare_transaction >2021-06-02 13:22:47,416: base.fill_sack() >2021-06-02 13:22:47,416: File "/usr/lib/python3.9/site-packages/dnf/base.py", line 397, in fill_sack >2021-06-02 13:22:47,552: self._add_repo_to_sack(r) >2021-06-02 13:22:47,553: File "/usr/lib/python3.9/site-packages/dnf/base.py", line 144, in _add_repo_to_sack >2021-06-02 13:22:47,553: self._sack.load_repo(repo._repo, build_cache=True, **mdload_flags) >2021-06-02 13:22:47,553: KeyboardInterrupt >2021-06-02 13:22:47,588: Failure resolving packages. I suppose this only affects systems using dnf (due to error from dnfhelper).
Worth noting that this SIGINT must happen during the loading animation before we present which packages are to be installed.
This seems to happen when we get a keyboard interrupt during subcommands run in tl-setup, not just dnfhelper. I get the following traceback if I send a SIGINT during Firewall configuration: >2021-06-02 13:59:48,281: Creating firewall service 'tlwebaccess' using ports 300:TCP >2021-06-02 13:59:49,096: Enable firewall service 'tlwebaccess' >2021-06-02 13:59:50,021: tl-setup aborted by user >2021-06-02 13:59:50,181: Failed to enable firewall service tlwebaccess >2021-06-02 13:59:50,181: Traceback (most recent call last): >2021-06-02 13:59:50,181: File "/usr/bin/firewall-cmd", line 40, in <module> >2021-06-02 13:59:50,182: from firewall.core.io.zone import zone_reader >2021-06-02 13:59:50,182: File "/usr/lib/python3.9/site-packages/firewall/core/io/zone.py", line 32, in <module> >2021-06-02 13:59:50,182: from firewall.core.io.io_object import PY2, IO_Object, \ >2021-06-02 13:59:50,182: File "/usr/lib/python3.9/site-packages/firewall/core/io/io_object.py", line 29, in <module> >2021-06-02 13:59:50,182: import xml.sax.saxutils as saxutils >2021-06-02 13:59:50,182: File "/usr/lib64/python3.9/xml/sax/saxutils.py", line 6, in <module> >2021-06-02 13:59:50,183: import os, urllib.parse, urllib.request >2021-06-02 13:59:50,183: File "/usr/lib64/python3.9/urllib/request.py", line 88, in <module> >2021-06-02 13:59:50,183: import http.client >2021-06-02 13:59:50,183: File "/usr/lib64/python3.9/http/client.py", line 71, in <module> >2021-06-02 13:59:50,183: import email.parser >2021-06-02 13:59:50,183: File "/usr/lib64/python3.9/email/parser.py", line 12, in <module> >2021-06-02 13:59:50,183: from email.feedparser import FeedParser, BytesFeedParser >2021-06-02 13:59:50,184: File "/usr/lib64/python3.9/email/feedparser.py", line 27, in <module> >2021-06-02 13:59:50,184: from email._policybase import compat32 >2021-06-02 13:59:50,184: File "/usr/lib64/python3.9/email/_policybase.py", line 9, in <module> >2021-06-02 13:59:50,184: from email.utils import _has_surrogates >2021-06-02 13:59:50,184: File "/usr/lib64/python3.9/email/utils.py", line 30, in <module> >2021-06-02 13:59:50,184: import datetime >2021-06-02 13:59:50,184: File "<frozen importlib._bootstrap>", line 1007, in _find_and_load >2021-06-02 13:59:50,185: File "<frozen importlib._bootstrap>", line 986, in _find_and_load_unlocked >2021-06-02 13:59:50,185: File "<frozen importlib._bootstrap>", line 680, in _load_unlocked >2021-06-02 13:59:50,185: File "<frozen importlib._bootstrap_external>", line 786, in exec_module >2021-06-02 13:59:50,185: File "<frozen importlib._bootstrap_external>", line 918, in get_code >2021-06-02 13:59:50,185: File "<frozen importlib._bootstrap_external>", line 587, in _compile_bytecode >2021-06-02 13:59:50,185: KeyboardInterrupt >2021-06-02 13:59:50,185: Creating firewall service 'tlwebadm' using ports 1010:TCP >2021-06-02 13:59:51,083: Enable firewall service 'tlwebadm' >2021-06-02 13:59:52,228: Creating firewall service 'tlmaster' using ports 9000:TCP >2021-06-02 13:59:53,170: Enable firewall service 'tlmaster' >2021-06-02 13:59:54,308: Creating firewall service 'tlagent' using ports 904:TCP >2021-06-02 13:59:55,202: Enable firewall service 'tlagent' >2021-06-02 13:59:56,215: Enable system firewall service 'ssh' >2021-06-02 13:59:57,321: failed to configure firewall.
