Date / time not updated at startup #292

Closed akki42 closed 11 months ago

akki42 commented 11 months ago

Using the newly released v 1.0.5, my TXT does not update date & time at startup.

According to /var/log/messages, ntpd is supposed to run as user ntp, which is not configured.

Manually calling ntpd without the -u option works fine:

(Without automatic or manual time setting, there are some resulting errors, e.g. Store app returns "Netzwerkfehler: SSL-Aushandlung fehlgeschlagen"...)

I cannot immediately reproduce the problem. I see two differences in my setup:

  1. in /var/log/messages, the time is correct from the first line
  2. I do not have this message about the ntp user

I guess that that some update did not work smoothly. My setup is not clean either. Before re-installing from scratch: Could you check if ntp is part of your /etc/passwd? I have

# cat passwd | grep ntp
ntp:x:101:102:ntpd user:/:/bin/false
hypnotoad commented 11 months ago

My guess is that in your case, the time battery is empty as well!

akki42 commented 11 months ago

Time battery indeed is (or seems to be) empty. I'll get a replacement asap.

Regarding user ntp: no such user is present in my system.

Full /etc/passwd reads as follows:

This is a rather fresh installation: newly installed v. 1.0.4 on October 7th and upgraded to v. 1.0.5 via sudo system-update 1.0.5 this Friday.

I can of course test a fresh v. 1.0.5 installation. The only reason I haven't done so already is that my wifi password contains a character (~) not shown in the TXT's wifi settings, so getting the TXT onto the network is a bit of a hassle.

hypnotoad commented 11 months ago

The problem happens during the upgrade of 104 to 105 and it can be fixed manually with

sudo adduser -s /bin/false -S -D -H -u 101 -G ntp ntp

I added this to the upgrade instructions. The tilde Logo will be on the keyboard in the next release.
