At the invitation to login screen I type in any userid and hit enter. I get a message about "corefile" and "segfault" and "glib_2" which QUICKLY disappears. In single user mode I'm looking around but don't see anything obvious. There is a corefile from 2 days ago from "ibus-daemon". I haven't investigated that core dump yet but wanted to run this situation by this group. Has anyone seen this problem? I am also able to recreate the problem in single-user mode by entering "su - anotheruserid" as root and then trying to su - root. This produces what looks like the segfault message I'm seeing when I attempt to login. glib_2 appears to be in the message as well. > > > > Any thoughts/hints/tips/suggestions would be appreciated. > > > > Best regards and STAY SAFE, > > This is likely the fprintd bug that Adam mentioned in the list > yesterday. ;( > > So, upgrade fprintd (or remove it). To actually *do* this, you can use rescue mode from an installer image. Boot an installer image, select 'troubleshooting' then the rescue mode, when it boots, tell it to mount the installed system when it asks you, then do 'chroot /mnt/sysroot' . Then you can update or downgrade fprintd, somehow. I'd suggest this: mkdir /var/tmp/upd cd /var/tmp/upd dnf -y install koji koji download-build --arch=x86_64 --arch=noarch fprintd-1.90.7-1.fc34 koji download-build --arch=x86_64 --arch=noarch libfprint-1.90.6-1.fc34 dnf update *.rpm that should do it. Then reboot and see if things are better. An alternative to rescue mode is to pass `systemd.debug-shell=1` as a boot param, which *should* give you a root shell with no authentication needed on tty9 (I haven't tested whether that actually works with the fprintd bug). -- Adam Williamson Fedora QA IRC: adamw | Twitter: adamw_ha https://www.happyassassin.net _______________________________________________ test mailing list -- test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to test-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/test@xxxxxxxxxxxxxxxxxxxxxxx
