Kernel oops issues in latest Debian Squeeze LTS kernel 2.6.32-48squeeze12
by Chris Samuel 17 Jun '15

17 Jun '15

Hi all, The latest security update for the Debian Squeeze LTS 2.6.32-48squeeze12 has some nasty regressions that cause lots of oops's according to posts on the debian-lts mailing list. IA32, AMD64 and PPC are affected (so far). Debian bug is: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=789037 debian-lits mailing list thread starts here: https://lists.debian.org/debian-lts/2015/06/msg00061.html Fingers crossed it gets fixed soon. cheers, Chris -- Chris Samuel : http://www.csamuel.org/ : Melbourne, VIC

Software Manager nor Synaptic won't start up
by Carl Turney 15 Jun '15

15 Jun '15

Hi All, Running a Mint Qiana 32bit MATE system. For the last month or two... Starting Software Manager gives no apparent response, as if nothing had happened. Starting Synaptic only gives the following error messages (and Synaptic won't run): ***** > An error occurred > The following details are provided: > > E: Encountered a section with no Package: header > E: Problem with MergeList /var/lib/apt/lists/ppa.launchpad.net_danielrichter2007_grub-customizer_ubuntu_dists_trusty_main_i18n_Translation-en > E: The package lists or status file could not be parsed or opened. > E: _cache->open() failed, please report. ***** Can anyone give a basic explanation of what's happened, and/or a step-by-step on how I can fix it? My Mint Qiana 64bit MATE system has (as far as I know) exactly the same programs, repositories, etc. and doesn't have this problem. Thanks very much in advance. Carl Turney

I have the first DVD of Debian 8.1 AMD 64 and will be getting the second disk latter this week. You are welcome to a copy. If you wish I can post you a USB key with the iso images, or even the two disks might be easier. These 2 disks will have 99% of whats required. I only have the first 2 as each iso image costs me $40 in line bandwidth. Lindsay, Near Benalla.

Hello All, More observing, now and then. This fragment from /etc/cups/cups-files.conf seems pertinent. # Default user and group for filters/backends/helper programs; this cannot be # any user or group that resolves to ID 0 for security reasons... #User lp #Group lp This in the light that all the bits and pieces I look at in the file manager appear to be owned by root. Perhaps this might be where I am having problems, such elements not being invoked because they have too much permissions? I am thinking of grabbing the ISO's of 8.1 when I can get near a broadband connection, hopefully, and a fresh install and see what happens. There is also the possibility of an earlier release, perhaps 5 or 6. A different direction is that I have magazine DVD's of SUSE and other distros. I have some idea now of what to go looking at and try to assess differences when things work. Regards, Mark Trickett

Hello All, Many thanks to Craig Sanders for some very valuable pointers. I have made some progress, but still not yet printing. markt@AcerNotebook:~$ uname -a Linux AcerNotebook 3.2.0-4-686-pae #1 SMP Debian 3.2.68-1+deb7u1 i686 GNU/Linux markt@AcerNotebook:~$ dpkg --print-architecture i386 My first thoughts from the uname command was that I had installed 64 bit, but no, the dpkg results was very informative. I managed to get hold of a later CAPT package than prior, thanks Craig for several steps. I managed to unpack and finally managed to install. As they were not listed in the available packages, synaptic did not see, but I did find ways with dpkg, when they were eventually in the right place. Significant use of sudo and even "sudo su" to sort out. The next stumble was not permitted to do admin in CUPS, solved that by adding myself to both lp and lpadmin groups. I know the default IP address of the printer, and leaving at factory default. Not certain of protocols at the moment, need some advice in due course. Now I can ping the printer, and get to the printer by ftp, but not yet printing. For this, I have a direct network cable. I am also struggling with NetManager, it has merit on a portable computer where I am attaching to various networks, but it also provides a stumbling block for setting up a fixed point. Having the interfaces unmanaged is a way I have tried, but I do not yet know enough to cope that way, nor am I coping with the interfaces managed. I comprehend what networking is about, and a lot of the detail, but a lack of practical experience is leading to mistakes and errors. I have a small switch/hub, TP-LINK TL-SF1005D, and trying to go through that does not work at the moment. I may have a defective cable, will do some more testing in due course. The printer address is 192.168.0.215, and eth0 is the wired connection on the notebook and I set that to 192.168.0.150. I am not well up on then setting the netmask and the like and would appreciate some pointers. Currently the network has only the two devices and no internet connection, although I am considering adding a RPi as a gateway device for the analog modem. Getting back to the printer, I am attaching two text files, one ftp'd from the printer, the other /etc/cups/printer.conf and I would appreciate thoughts on the protocol, currently try to print a test page and get a "Unable to write print data: Broken pipe" message on the CUPS web page while monitoring the attempt to print a test page. I hope that describing some of what I have done is helpful to other newer users. I can nose around, but without reason to use and refresh, too much slips away. Approaching 60, I no longer learn quite like I did in my 20's. Regards, Mark Trickett

Iceweasel or ABC has sand in the gears?
by Erik Christiansen 10 Jun '15

10 Jun '15

While youtube clips show (watchable, but not entirely smooth) motion in iceweasel on my new debian 7.8.0 install, ABC clips bearing the simple two-circle Venn diagram symbol in the TLH corner show only a static video image, and even the audio feed is interrupted. Is there some way to diagnose where the pipe is most constricted? (The 10 MB file at http://mirror.internode.on.net/pub/test/ took 20 seconds.) Does anyone else have trouble with the ABC's new video clip dingus? Erik

Re: CUPS and "broken pipe" and Canon LBP-5050N
by Mark Trickett 10 Jun '15

Hello All, Still chasing, but a slightly different tack. When I set it up, it sets to "socket://192.168.0.215" which research shows as the HP JetDirect protocol. There are comments in the CUPS documentation that the vendors implement the IPP (Internet Printing Protocol) with deficiencies that mean it is better to use other protocols. Does anyone here have any information to contribute? I do not want to run Windows, but will set up a Windows box if necessary and sniff the packets to see what is going on. That will take undue time and effort at the moment, but would provide real answers. If anyone can find answers where someone has done any of that, I would very much appreciate information. I would still appreciate a bit of a network primer about the netmask and the like. I also need to "discover" the ip address of the switch I have, it does not respond at what I have found on the net as the default ip address. Regards, Mark Trickett

CUPS and "broken pipe"
by Mark Trickett 10 Jun '15

10 Jun '15

Hello All, Have continued looking hither and yon and cannot find what specifies invocation of filters and the like, cannot see where there might be a broken pipe. Is it piping between filters and programs, or perhaps the networking. Still not certain. Regards, Mark Trickett

It has already been pointed out that relatime is default now. It would be interesting to compare the amount of data written for that vs for other operations. Modern SSDs are designed for significant volumes of disk writes. When you use an SSD as a ZIL for a ZFS filesystem it will get a copy of all data that is written to the entire RAID array. We aren't seeing reports of SSDs failing when used for a ZIL. Some previous analysis of potential SSD lifetimes on this list suggested that they should be good for at least 5 years. If that was the case then they would often outlast hard drives. If your data is important then you will have multiple drives used in some form of RAID array or really good backups (in the case of systems that can't do RAID such as typical laptops). So you shouldn't be particularly worried about the life of SSDs. As with hard drives you can expect them to last long enough that you want bigger ones before they wear out. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
