[Bug 1906918] Re: Rsyslog can't write to sympa.conf log file because of missing permissions

2020-12-10 Thread Henning Kockerbeck
As it turned out after further investigation, changing the log file's
group from sympa to adm, plus changing the mode to 640, seems to be
sufficient to give rsyslog access. As the config fragment for logrotate
uses the same attributes to create new logfiles, I'd say this is the
best solution.

[Bug 1906918] [NEW] Rsyslog can't write to sympa.conf log file because of missing permissions

2020-12-05 Thread Henning Kockerbeck
Public bug reported:

Sympa is sending its log messages to rsyslogd, which is supposed to
write them to /var/log/sympa.log. But this file is owned by sympa:sympa,
so rsyslogd can't write to it. If it tries, you get errors like

-
Dec  4 23:55:51 sympa-test rsyslogd: file '/var/log/sympa.log': open error: 
Permission denied [v8.2001.0 try https://www.rsyslog.com/e/2433 ]
Dec  4 23:55:51 sympa-test rsyslogd: action 'action-8-builtin:omfile' suspended 
(module 'builtin:omfile'), retry 0. There should be messages before this one 
giving the reason for suspension. [v8.2001.0 try https://www.rsyslog.com/e/2007 
]

in /var/log/syslog. Sympa's log messages go to syslog, too.

This could possibly solved in two ways. One is to hand sympa.log over to
a fitting owner and group like syslog:adm. But I don't know whether or
in what way Sympa itself needs access to sympa.log, so this might not be
the best solution.

The second way is to extend the rsyslogd conf for Sympa in
/etc/rsyslog.d/sympa.conf. You can set the file owner before the config
and reset it after. This would look similar to

-
$fileOwner sympa
:programname, contains, "sympa" /var/log/sympa.log
:programname, contains, "wwsympa"   /var/log/sympa.log
:programname, contains, "archived"  /var/log/sympa.log
:programname, contains, "bounced"   /var/log/sympa.log
:programname, contains, "bulk"  /var/log/sympa.log
:programname, contains, "task_manager"  /var/log/sympa.log
$fileOwner root
-

This problem appears in Ubuntu 20.04.1 with the package version
sympa_6.2.40~dfsg-4.

[Bug 1605117] Re: Unity greeter indicators don't show on second launch

2016-08-08 Thread Henning Kockerbeck
Mostly for the records, I've had a very similar, but more severe
problem. Since upgrading from 14.04 to 16.04, not only were the
indicators (other than a11y) missing, but I couldn't log in anymore. The
correct password was reproducibly rejected as incorrect. After the next
restart of lightdm, things worked smoothly, until the next logout. I'd
reckon that the same cause that kept the indicators from loading kept
lightdm from connecting to its source of authentication (PAM?), but
that's highly guesswork.

The new 1.18.2-0ubuntu2 so far seems to have fixed that variant of the
problem, too.

[Bug 1315966] Re: banshee crashes on startup

2014-09-22 Thread Henning Kockerbeck
I'm affected by this as well. When I add specific podcasts and close the
application, Banshee crashes at the next start. It doesn't happen with
every podcast, but with those that do invoke the crashes the problem is
reproducible.

Some (arbitrarily chosen) examples:

WDR 2 Kabarett (http://www1.wdr.de/radio/podcasts/wdr2/kabarett132.podcast) - 
breaks Banshee
WDR Quarks  Co (http://podcast.wdr.de/quarks.xml) - breaks Banshee
Pentacast (http://www.c3d2.de/pentacast.xml) - does not break Banshee
IT-Cast (http://www.it-cast.de/?feed=podcast) - does not break Banshee

In my opinion this looks like a problem with special characters, string
encodings or something in that venue. Maybe the crash casts have some
kind of problematic character in the podcast name, an episode name, an
episode description etc. When the podcast is added, this gets stored in
Banshees database, and at following restarts the application trips over
it badly.

There's another observation that may help you to find the cause of the
problem: I've been listening to the first podcast from the above list
for several years with Banshee, and it never gave me problems. This was
on an Ubuntu machine that was upgraded with every release from 2010 or
2011 to 14.04 LTS. Recently, I got a new machine that I installed 14.04
LTS on, and the WDR 2 Kabarett podcast makes Banshee crash every time I
tried to add the podcast. In my opinion this indicates that it's rather
a problem of getting the data into the database when adding the podcast
in contrast to loading data that previous versions (of Banshee? of Mono?
of SQLite?) wrote to the db.
