Which should be some years away - I've only had this one about a year. Unless, of course, I'm forced to remove HPLIP by some upgrade or other in the mean time. As I've said previously, a future CUPS will not support printer drivers. HPLIP provides printer drivers. There will be little point in Debian packaging HPLIP, wouldn't you agree? But this is a few years away. Stick with what you have (it works) but think about getting ahead of the game. We'll see at that time, especially since what I read from https://wiki.debian.org/CUPSDriverlessPrinting makes it unable to handle the cases where you must use a print serer or the one where you're not on the same network as the printer. Perhaps cups-browsed migt help you. No all zeroconf based scheme is limited to the local (L2 network). And printer on a separate network is the standard setup in offices.

Dan's point is that while ECC memory is indeed safer than non-ECC memory, this is true whether one is using ZFS or some other filesystem; furthermore, with or without ECC memory, there's no reason to believe that ZFS is less safe than the alternative. See: https://arstechnica.com/information-technology/2020/05/zfs-101-understanding-zfs-storage-and-performance/?comments=1&post=38877683 https://jrs-s.net/2015/02/03/will-zfs-and-non-ecc-ram-kill-your-data/ So while ECC memory is always good, it's not a consideration when trying to choose between ZFS and other filesystems.

Benchmarks would be informative, but STFW I am unable to find such. - ECC memory is safer than non-ECC memory. This is true, but there is nothing that makes ZFS more dangerous than another filesystem using non-ECC memory. I think the amount of danger depends upon how you do your risk assessment math.

Not stated strongly enough. Nobody should turn on dedup; people who think they are experimenting should definitely not turn on dedup; only people who have a completely sacrificial system and a good knowledge of the data to be stored should consider dedup. This article has some good information: https://www.truenas.com/docs/references/zfsdeduplication/ I have been running deduplication for several years on my SOHO servers, which have HDD's and SATA3 SSD caches. Normal read/ write operations can fill the Gigabit network, but replication is very slow (5.8 MB/s for a recent replication job).

The OP claimed they have nothing pinned, but presented no evidence to support this claim. Perhaps they thought that because they didn't explicitly *pin* anything themselves, there must not be anything pinned on their system. So why bother looking?

Yes it's laser but the reason I am writing this message regard something else. It's the support of MOPRIA. Even if it's mostly made for Android, what it does is offer a discovery and printing protocol compatible with all CUPS system (will publish IP endpoint that support PostScript, PCL and PDF, all depending on the printer but at least one of them). Regarding the scanner, it will support sending by email thru the use of a SMTP server account. So I think we can say these devices will be supported by Linux (and Debian). Here's the link for Mopria association. https://mopria.org/certified-products Even if my model is not listed there (B205), on the Xerox website it says that it's supported. > (If your remark is along the lines: "not inkjet, laser" or "not > all-in-one, separate devices", save your time, I have already heard the > arguments and I know the constraints I am working with.) > > Thanks in advance. > Hope this shine a light to something nice to be investigated. > Regards, > -- Polyna-Maude R.-Summerside -Be smart, Be wise, Support opensource development OpenPGP_signature Description: OpenPGP digital signature

Hi, I dunno if this message will be of any use, because other suggestions indicate that this might be due to pinning or other issues that I have no knowledge of.

Nevertheless, you've given the answer yourself in your first mail. LVM2 is the current solution for logical volume management and it does what it is expected to do. Whatever file systems, partitions, logical volumes or arbitrary stuff like raw partitions, empty spaces or spares you want, you can put them on LVM logical volumes and wipe them off there if you want so.

Re: apt-upgrade (Bullseye) shows 1 pkg not upgraded
Hello, If for example you have set up unattended-upgrades and installed apt- listbugs, then when unattended-upgrades runs, apt-listbugs automatically pins (-3) upgradable packages that are affected by bugs in order for them to be hold until a fix. They are automatically de-pinned when bugs are fixed. Such pinned packages appear in /etc/apt/preferences.d/apt-listbugs (look at apt-listbugs manpage for details)

If you answer those questions, I'm sure somebody will be able to give you good advice.

There will be little point in Debian packaging HPLIP, wouldn't you agree? But this is a few years away. Stick with what you have (it works) but think about getting ahead of the game. -- Brian.

Thank you for these very helpful general informations, and thanks to Brad for the specific information about the particular model. About Brother: the only model worth considering for us is the DCP-J1200DW, and it is only a little cheaper than the HP, and the characteristics of the HP are a little better, including double-sided printing which is not necessary for our use but still a nice thing to have. Considering that AFAIK Brother is more reputed for its laser printers than for all-in-one inkjets and that I want to recompense being a stalwart supporter of Linux printing, I think I will stay with the HP.

Disk for a small server
Ciao a tutti, I have a little server (debian stable on raspberry) used by my family and a little set of people (~10) with services like nextcloud (~100GB growing) and some more. This server has an external disk for the data, disk that is becoming too little so I would like to change it with a bigger one (1TB) and I would like to arrange this new disk in a confgurable fashion, so I would change the partitions on the way.

There is also ~/.xsession-errors, but you probably lost access to your own home dir. As root do: $ chown -R joe /home/joe and login as joe Create another user and try login with it. Does it work? If it doesn't work: Make sure that ``/tmp`` folder has full write permissions of everyone. If not, fix it Disable graphical login i.e. (``systemctl set-default multi-user.target``) and reboot.

Bob Bernstein writes: > Full disclosure: In a typical Bob fit of impulsivity I, yes, edited > this file using 'sudo nsno /etc/sudoers'. In general, consider making a backup of config files before editing. Here's a sudo mini course: - Consider what needs to run as root and only run that command with sudo. - To edit a file: sudoedit file - Sometimes it's just easier to to run a shell as root: sudo -s For documentation: - man sudo - man sudoers > Alright, enough fooling around.

Wow, I didn't know most is still around. I remember using it a long time ago but I've stuck with less. I guess mostly because it's a lot more likely to be available than most as I use Linux systems that I don't manage myself as well... Anyways, the mc manual says mc uses the builtin viewer unless "Use internal view" option is disabled, otherwise it uses PAGER or VIEWER. Seems to work for me for both less and most.

can't login via gdm
Hello List,
I ran the following to change my users UID & GIDs - but, now I have no
graphic gdm login. I have no problem with a terminal login and the
same worked on a terminal based server.
After boot, gdm attempts to start but fails with a blinking cursor in
the top left corner - I can switch to tty2 etc. Does anyone know what
stupidity I may have inflicted upon myself?
Commands executed:
# usermod -u 1003 guest
# usermod -u 1002 joe
# usermod -u 1001 blow
# groupmod -g 1003 guest
# groupmod -g 1002 joe
# groupmod -g 1001 blow
# find / -user 1002 -execdir chown 1003 '{}' \;
# find / -group 1002 -execdir chgrp 1003 '{}' \;
# find / -user 1001 -execdir chown 1002 '{}' \;
# find / -group 1001 -execdir chgrp 1002 '{}' \;
# find / -user 1000 -execdir chown 1001 '{}' \;
# find / -group 1000 -execdir chgrp 1001 '{}' \;

I am new to using sudo. All suggestions bearing even the slightest hint

Space separating the '%' and the group name ('sudo') does not strike me

My /etc/sudoers hasn't that. 'man 5 sudoers' format specification shows no space between the '%' and the group name. By that guidance, it looks wrong and I would remove it.
