What does this mean and how do I solve these errors:
error 1:
kernel: cdc_wdm 2-1.4:1.8: wdm_int_callback - 0 bytes
error 2:
kernel: cdc_wdm 2-1.4:1.5: wdm_int_callback - 0 bytes
error 3:
lightdm[69066]: gkr-pam: unable to locate daemon control file
I got these errors with this command in journalctl:
sudo journalctl -p 3 -xb
I don’t understand these errors and wish to solve them.
Seems to be related to a 3G/4G/GSM modem either your laptop has, or is connected via USB. Probably you need to install modem-manager-gui from community repository.
Most likely the gkr-pam runs before the system initializes the rest of the session, so the gnome-keyring daemon that has to be unlocked does not yet run when first check happens, but if you have no issues logging in your desktop, then is just a log entry that you can ignore.
