Motd wrong

yab · March 29, 2022, 9:44am

Platform information:
- Hardware: raspberry pi 3B
- OS: openhabian installed from 1.7.1

Once in a while, openhabian-config decides to show motd when started. As you can see below, the text shown (no. of updates available) is wrong. I don’t think, this is intended, is it!?!

##   Updates = 11 apt updates available.
##  Sessions = 1 session(s)
## Processes = 114 running processes of 32768 maximum processes

FireMotD is a third party application. If there is a problem with it that problem will need to be solved through their project.

But I believe that FireMotD only runs apt periodically to find the number of available updates. It is not unusual for it to list a different set than what is actually available.

yab · March 29, 2022, 3:23pm

Thanks for your reply, Rich! I know a bit about firemotd. But i do not believe this is causing the “fake news” above. The news had been created a while (days) before the login it is shown. An i think this to be an openhabian problem. Or maybe it’s intended (or just accepted), you never know: some days ago there were 11 apt updates available.

Wolfgang_S · March 29, 2022, 7:21pm

What is the timestamp and the content of file /usr/share/firemotd/data/FireMotD.json ?
That file is generated by scheduled runs of FireMotd.
bash_profile entries just display its entries + more data.

yab · March 29, 2022, 7:34pm

I logged in and had a look to answer your question - which isn’t helpfull at all:

$ ls -l /usr/share/firemotd/data/FireMotD.json
-rwxrw-rw- 1 root root 3086 29. Mär 21:29 /usr/share/firemotd/data/FireMotD.json

3 minutes later fpr reference - sorry about the delay:

$ date
Di 29. Mär 21:32:10 CEST 2022

I forgot to mention, that the problem above does not occur on every login when the message is shown. So it’s wrong every now and then from every now and then it is shown at all.

Wolfgang_S · March 29, 2022, 7:39pm

Although mine is dated at 21:14 CEST.
It contains an entry besides others:

 "Updates": {
    "Generated": "@cron",
    "Type": "apt",
    "Count": "15",
    "LastRun": "2022-03-29 05:13:02,118"
  },

That shows how many updates are available and that it was calculated at 05:13 by scheduled cron.

yab · March 29, 2022, 7:51pm

That’s fine. But nothing worth for the user i think.

Wolfgang_S · March 29, 2022, 8:17pm

Sorry, then I must have misunderstood your initial post.

yab · March 29, 2022, 8:27pm

Oh well, that’s my fault: i think i understand, what happens. I do not understand why / what is it good for.

yab · April 10, 2022, 9:01am

Some able an willing to provide info about old info shown at times when logging in to openhabian (current version, updated from 1.7.1, for openHAB 3.2)? If so: can you please stop this or tell us what sense this makes?

Wolfgang_S · April 10, 2022, 9:10am

I was and I am willing to help…
Sorry, to write and I am repeating myself. Could you please have a look to /usr/share/firemotd/data/FireMotD.json . As far as I understand the firemotd script that file contains parts of the information that is being parsed and shown on your screen. That file is updated during nights and not during login times. I am asking you to check that files content to proof my theory. It either will confirm it then the number of updates and a timestamp when this information was collected is available. Based on that one we can continue.

yab · April 10, 2022, 9:44am

Sorry, i think i did not read your previous posts attentively.

  "Updates": {
    "Generated": "@cron",
    "Type": "apt",
    "Count": "0",
    "LastRun": "2022-04-10 05:56:28,170"

Wolfgang_S · April 10, 2022, 2:38pm

ok. That indeed looks a bit strange.
As far as I read this the information in the json file is created at 05:56 in the morning of 2022-04-10.
While your log in took place at around 10:54.
Although you stated that your openhabian version is 1.7.1 could you give me a favor and check for the exact openhabian-config version ? It is displayed in the about menu as well in the main menu header and it looks like:

openHABian Configuration Tool — [openHAB3]{2022-03-27T13:22:11-06:00}(1305ac7)

yab · April 10, 2022, 4:29pm

openHABian Configuration Tool — [openHAB3]{2022-03-27T13:22:11-06:00}(1305ac7)

And this is not a copy from your post.

More Info: when i logged in after running 02 (Upgrade System), “0 apt updates available” showed up correctly.

yab · April 10, 2022, 10:05pm

Maybe the nightly run should create/update ~openhabian/.firemotd-cache, see ~openhabian/.bash_profile. Seems like half implemented workaround for FireMotD taking to much time.

What i do not understand up to now is, why the FireMotD generated text is not shown on every login.

Wolfgang_S · April 16, 2022, 7:51am

I did not check if that action is CPU intensive and how long it takes. What about running it more often ?

on my system it takes about 3 … 4 seconds. If you can wait the file can be created during login time.

what do you mean ? sometimes the whole content is not shown ?

Are you interested in all these values ? What about checking if e.g. the updates can be removed from being displayed - would that be sufficient or would you like to see it ?
As ( not optimal ) workaround you can create a cronjob for user openhabian that creates the cache during morning hours ( as you suggested ).

yab · April 16, 2022, 11:27am

Just to make shure: we are talking about unmodified openhabian. And i won’t go an change it. I think it does not make sense to show a status form “last night” when logging in in the evening and therefore expect this to be changed in openhabian - but maybe i’m wrong.

Yes. F.e. it happend when i logged in right now.
