Paconky: displays repo and AUR pkg info in conky

Lennie · 2012-01-26 15:17:24

I have the same problem. It usually only shows the updates from AUR, only occasionally it shows updates from the official repository.

I hope it can be fixed. It was great to always know if there were updates, and for which packages.

Xyne · 2012-02-04 05:10:33

Repo databases are downloaded by the pyalpm backend. It seems that pyalpm might not be handling HTTP errors correctly, because I see several error messages about failing to download different databases each time it is run.

This doesn't seem to be a direct paconky issue because the script on the site is the one that I am using, and I see all of the available updates. Presumably it manages to get all the databases after it runs a few times. You can try changing your main mirror to see if that helps, otherwise send the error messages to the pyalpm developer.

Btw, even if you see new packages when you run pacman -Syu, it doesn't necessarily mean that paconky isn't working. The update interval should be set to two hours, and the main mirror releases scripts in a cronjob (I think), so it may release hundreds of packages between 2 update intervals.

Lennie · 2012-02-04 08:43:55

Thanks. I changed mirror and now it works.

amsri · 2012-02-08 08:42:29

After I changed mirrors it started working but now again it doesn,t seem to be working, It is only saying all packages up-to-date while there are actually updates available.

Lennie · 2012-02-08 21:48:34

It seems that it only works after running pacman -Syu.

damacas · 2012-02-08 22:37:16

I have tried changing the mirror several times with no change. I can confirm Lennie's observation that it seems to work following a pacman database sync.

forkboy · 2012-02-09 20:07:31

Confirmed not working properly here too

Xyne · 2012-02-16 10:30:50

I've updated the script. Please try it and let me know if it works.

damacas · 2012-02-16 22:48:48

I updated the script, but I am having the same issues. No notice of updates until I:

pacman -Sy

After that it reports the update-able packages.

Xyne · 2012-02-17 09:03:51

I have uploaded another version. Please try again.

Lennie · 2012-02-17 12:51:50

Now it seems to work for me. It shows one new package in extra, and I don't remember having run pacman -Sy... Nice to have it working again. Thank you.

damacas · 2012-02-17 12:55:33

Great that did it here too.

damacas · 2012-02-19 03:18:00

Hmm, well the script seemed to be working fine all day. Successfully reported new packages several times...and then:

jasonwryan · 2012-02-19 03:19:27

The AUR is down at the moment...

damacas · 2012-02-19 13:29:50

OK, thanks jasonwryan, now that makes sense. All is working again.

forkboy · 2012-02-19 15:11:47

Afraid it still doesn't work for me...

EDIT: apologies, it does appear to work now

I've moved the script on the server with the last server update. The link in the first post has been updated.

Xyne · 2012-02-26 17:48:33

Bumping just to say that I've added exception handling to the db sync loop. It should now display something even when it fails to download some of the databases.

tjpp · 2012-03-08 18:53:23

Today, after an upgrade I got

Xyne · 2012-03-08 22:59:56

Strange.

Try re-installing python3-xynexdg.
If it still doesn't work, post the output of "pacman -Qi python3-xynexdg" and "pacman -Ql python3-xynexdg".

tjpp · 2012-03-12 14:06:11

I had:

Surprisingly, AUR is more recent than xyne-any. Now everything works. Thanks a lot

Xyne · 2012-03-12 15:19:58

So everything is working again?

enifeder · 2012-04-03 05:09:19

I am getting the following errors when trying to run this.

Traceback (most recent call last):
  File ".scripts/paconky.py", line 238, in <module>
    main(sys.argv[1])
  File ".scripts/paconky.py", line 189, in main
    os.rename(tmp_local_db_path, tmp_local_db_path + '.old')
OSError: [Errno 20] Not a directory

Can someone let me know what is going wrong here,
Thanks.

Xyne · 2012-04-03 16:26:05

@enifeder
It probably means that you have something in the temporary database that shouldn't be there. What path are you passing to paconky? Check what's in that path.

I've updated it to handle such cases gracefully, but you should check what caused it.

I am calling paconky with the following:
