This had nothing to do with my earlier issue however. Anyway, hopefully a new CUPS update will get things working soon. Thanks.
Can't print: /var/spool/lpd
Hi, I'm having an issue with a Brother HL-3150CDN printer on Debian Testing. The printer functions with the drivers CUPS offers by default, but the official Brother's drivers has some options that I need to work with the equipment. I was able to install these drivers some time ago, but now they didn't seem to work. The two file to install are: hl3150cdnlpr-1.1.2-1.i386.deb hl3150cdncupswrapper-1.1.4-0.i386.deb Both for 32-bits, so, I did the: $ sudo dpkg --add-architecture i386 $ sudo apt-get update And then used apt-get to install them. The packages get installed but didn't seem to send the data to the printer at printing time. Any idea how to diagnose this? The only error I'd saw until now is when I install the lpr package: $ sudo apt-get install ./hl3150cdnlpr-1.1.2-1.i386.deb (...) mkdir: no se puede crear el directorio «/var/spool/lpd/hl3150cdn»: No existe el fichero o el directorio chown: no se puede acceder a '/var/spool/lpd/hl3150cdn': No existe el fichero o el directorio chgrp: no se puede acceder a '/var/spool/lpd/hl3150cdn': No existe el fichero o el directorio chmod: no se puede acceder a '/var/spool/lpd/hl3150cdn': No existe el fichero o el directorio Any hint what could/should I do?

It is an administrative policy tool to prevent access to volumes in the time it takes to move them." Just move the disk and the lvm stuff will show up like normal. The only potential gotcha is if you used the same volume group names on both systems, then that would need to be resolved (by renaming one of them)
Migrating LVM volumes to a new machine
Hello I would like to understand how to move a LVM VG from one machine to another, when the disk to be moved contains filesystems key to the source system. I have read section 13.6 of the LVM HOWTO which talks about moving VGs. However the context of my situation is I am cannibalising an old machine and moving the VG that contains the LVs mounted on /, swap and /home of the source machine. That, apart from the non-LVM /boot partition, is all that is on this SSD. The disk will not be the primary disk on the new machine, and the new machine's /, swap and /home will be elsewhere, but I will want to be able to access the current contents of the disk from the old machine on the new machine for a period of time before I decide to wipe it. I feel like I can't follow the instructions in the HOWTO because it wants me to unmount the file systems, export the LVs and so on, on the old machine before moving the disk, and I don't see how I can do that on a system that is expecting to use those file systems to operate. I thought of booting a live system from a USB stick, so the affected LVs aren't mounted or in use, but then I'll face the problem of how to get the live system to be aware of the LVM setup existing on the SSD. I guess the bottom line is I am missing some understanding of how LVM works in detail, and in particular how a machine that didn't create a particular VG and its contents can nonetheless be made to recognise it. Can anyone fill me in? Thanks Mark

Emacs erreur de chemin vers clang-format.el
Bonjour à toutes et tous, J'ai commencé à rédiger ce courriel comme une question, mais j'ai trouvé la solution en cour de rédaction : Comment éviter de coder en dur "/usr/share/emacs/site-lisp/clang-format-11/clang-format.el" ? dans mon ficher de config d'emacs j'ai indiqué ça : (load "/usr/share/emacs/site-lisp/clang-format-11/clang-format.el") (global-set-key [(meta f)] 'clang-format-buffer) Après un mise à jour du paquet debian clang-format c'est passé de 9 à 11. Emacs me disait qu'il ne trouvait pas clang-format.el dans : "/usr/share/emacs/site-lisp/clang-format-9/clang-format.el" J'ai longtemps cherché avant de m’apercevoir que c'est moi-même qui ai codé ce chemin en dur... Au départ, j'ai fait comme indiqué ici, https://stackoverflow.com/questions/59690583/how-do-you-use-clang-format-on-emacs-ubuntu mais indiquer un chemin en dur c'est toujours mauvais. Du coup il faut remplacer la première ligne : ;;(load "/usr/share/emacs/site-lisp/clang-format-11/clang-format.el") (require 'clang-format) (global-set-key [(meta f)] 'clang-format-buffer) Par (require 'clang-format) Emacs a le chemin vers clang-format.el dans la variable 'load-path Comme indiqué ici : https://www.emacswiki.org/emacs/LoadPath Voila poser la question c'est y répondre, comme on dit ! ;-) -- Benoit Sent with [ProtonMail](https://protonmail.com) Secure Email.

Check the groups for user pi. Check the groups for paulf. If you make the groups the same, what error results? Part of this at least is perhaps, because Raspberry Pi OS is set up to anticipate a pi user - hence the suggestion to try Debian Andy C > 2.

There is too much level of complexity in this issue from what I read already: 1. it is RaspberryPI OS (based on debian but there is also dedicated list where it could be answered more efficiently) 2. The actual user plugging the external disk is paulf but disk mounts as default user pi 3. Who knows how is exactly samba pre-configured Last but not least I was thinking of simply restarting samba server after plugging in - this way whatever is there should become visible.

This could mean that your fstab entry (that you mentioned in other messages) is ignored and the partition is mounted by some other means (e.g. a Raspbian specific boot script). These kind of unknowns are exactly the reason why subscribers of debian-user will be reluctant to even try to help with anything else but a pristine Debian system. > ls -ld: > drwxrwxrwx 3 pi users 4096 Dec 10 16:45 /media/pi/music Ok, what about permissions for the /media and /media/pi directories? This is likely my last attempt to help with your troubleshooting as I have only limited and less than recent experience with Samba.

When it boots and mounts the drive, it mounts it under the pi user. I don't know what wizardry they use to accomplish this, but that's how it works. I'm not sure what wizardry is used to make this happen, but I've now enshrined it in the fstab file. Again, where the drive mounts is incidental to the original question. Paul -- Paul M.

According to (1) AC9260 is supported by a Li,nux kernel from 4.14 on. According to (2) Strecth has a 4.09 kernel but there is a 4.19 Backports kernel available. According to (3) there is also a firmware for this chip in the Backports repo By default Stretch seems too ancient to support your chip and you would need is install both the kernel and the firmware from Backports to support it (1) https://www.intel.com/content/www/us/en/support/articles/05511/network-and-i-o/wireless.html (2) https://packages.debian.org/search?suite=all=all=any=names=linux-image-amd64 (3) https://packages.debian.org/search?suite=all=all=any=names=iwlwifi If you do not know how to use Backports, there is a page in the wiki: https://wiki.debian.org/Backports

I can't vouch for it firsthand, but at least there seems to be firmware for it -- at least this seems promising: tomas@trotzki:~$ apt-file search -x "firmware.*9260" firmware-iwlwifi: /lib/firmware/iwlwifi-9260-th-b0-jf-b0-34.ucode firmware-iwlwifi: /lib/firmware/iwlwifi-9260-th-b0-jf-b0-38.ucode firmware-iwlwifi: /lib/firmware/iwlwifi-9260-th-b0-jf-b0-41.ucode firmware-iwlwifi: /lib/firmware/iwlwifi-9260-th-b0-jf-b0-46.ucode But perhaps someone else is using that hardware right now.
