Welcome back to another edition of Questions and Answers! In this section we will endeavour to answer your Ubuntu questions. Be sure to add details of the version of your operating system and your hardware. I will try to remove any personally identifiable strings from questions, but it is best not to include things like serial numbers, UUIDs, or IP addresses. If your question does not appear immediately, it is just because there is such a lot, and I do them, first-come-first-served.
Bienvenue de retour dans un nouvel épisode de Q. ET R.! Dans cette rubrique, nous essayerons de répondre à vos questions sur Ubuntu. Assurez-vous d’ajouter les détails de la version de votre système d’exploitation et de votre matériel. J’essaierai d’enlever de vos questions toutes chaînes qui pourraient vous identifier personnellement, mais il vaut mieux ne pas inclure des choses comme des numéros de série, des UUID ou des adresses IP. Si votre question n’apparaît pas tout de suite, ce n’est que parce qu’il y en a beaucoup et que je les traite sur la base de premier venu, premier servi.
Have you ever just had one of those days? We sold (I say we, but it was a department store selling our brand) the first batch of plasma big screens and it wasn’t long before a truck stopped and offloaded four faulty ones the store wanted replaced. We had procedures in place, and even though my branch manager had promised the store manager swap-outs, we checked each one before doing so. The problem was that I could not swap them as they all had water damage. Turned out they were from the same client and the store swapped them on their no quibble policy. We, however, did not have that policy, so everything got checked and repaired. Since we would not honour the warranties on the four previous screens, they had to refuse the fifth swap-out and also did not refund the client amid threats to get her solicitors involved. Turns out that her housekeeper had been over watering the pot plants on the shelf above the Screen and it started dripping water after about 2 minutes. So every Monday the screen got damaged and every Tuesday it was back at the store for a swap-out. I would not want to be that store manager, having to explain to the client they are now liable for 5 screens. Anyway, my take away today is to check something before raising your hand and saying it’s faulty. You may see the issue, even if you don’t know how to fix it. Saying “maybe it’s this?” could help more than you think. Just don’t repeat things you have not seen or know nothing about. (Such as explaining how you heard the multiplexer has been affecting the power supply in your laptop. Causing the network port to go faulty.)
Avez-vous déjà eu une de ces journées ? Nous avons vendu (je dis « nous », mais c'était un grand magasin qui vendait notre marque) le premier lot de grands écrans plasma et, en peut de temps, un camion s'est arrêté et ena déchargé quatre qui étaient défectueux et le magasin voulait qu'ils soient remplacés. Nous avions défini des procédures et, bien que le responsable de ma succursale ait promis le chef du magasin qu'on changerait les défectueux, nous avons vérifié chacun avant de le faire. Le problème était qu'il m'était impossible de les échanger puisque tous étaient endommagés par l'eau. Il s'est avéré qu'ils venaient du même client et le magasin les avait remplacés selon leur politique de retour. Cependant, nous, nous n'avions pas cette politique et donc tout était vérifié et réparé. Puisque nous avons refusé de respecter les garanties sur le quatre écrans précédents, ils étaient obligés de refuser le cinquième remplacement et, en outre, n'ont pas remboursé le client , malgré ses menaces d'impliquer ses avocats. Il s'avère que sa femme de ménage avait arrosé les plantes en pot sur l'étagère au-dessus de l'écran et l'eau commençait à s'égoutter après environ 2 minutes. Ainsi, chaque lundi l'écran était endommagé et, chaque mardi, le voilà au magasin pour un remplacement. Quoi qu'il en soit, mon conseil du jour est de vérifier quelque chose avant de lever la main et dire que c'est défectueux. Vous pouvez reconnaître le problème même si vous ne savez pas le réparer. Dire « c'est peut-être ceci ? » pourrait aider plus que vous ne croyez. Ne répétez surtout pas des « faits » que vous n'avez pas vus ou dont vous ne savez rien. (Tel qu'expliquer que vous avez entendu dire que le multi-plexeur affecte l'alimentation dans votre ordinateur portable, rendant le port réseau défectueux.)
Q: Perocha, [2022/04/20 16:33] I made the switch to Ubuntu 22.04 and decided to uninstall Firefox snap. The issue I ran into was that there are no other browsers I could install to get the firefox-deb. What is the way sensei? The answer needs to involve the terminal please, it’s just so much faster. A: Actually there are some, but they all blow for regular users. You could install deb-get from the command line, then use deb-get to install opera(opera-stable) or brave(brave-browser) or vivaldi(vivialdi-stable). I’m not sure if Firefox was there. Q: Hai, I installed Ubuntu 22.04 for the first time as my laptop is 14yrs old and needs new bling. My question is, is CD writing still a thing? I heard that it is an issue on Linux due to licensing? Anyways I opened Synaptic and searched for dvd writer and came up empty. I would like to make and restore some simple backups. XP served me well, but getting updated/new software is out of the question. A: I know Xfburn works on Ubuntu 22.04, but you have options, like Brasero, K3b, etc. I repeated your search and saw the issue, maybe search for DVD burning, Synaptic can be pedantic sometimes.
Q: Good morning/evening, I want to ask a question not so much about Ubuntu, but about software FOR Ubuntu. You see, I have been using WeKan, https://wekan.github.io/ but I want something offline that I can keep, not self host. I don’t want to set up my own cloud. (the advice I have been getting) It just makes my life easier when I can see what is next without needing a network or internet. I work from home and my office is a little Wendy, with just power.
A: Yes, I agree, I don’t want my data held hostage either. You could try Brisqi, it has an installer, see above regarding deb-get and you do not need to be online to use it, only if you would like to share data between devices. You can skip the online login and start using the product locally.
Q: My MSI radeon is giving me grief all the time. I get random freezes, graphics corruption, weird issues I did not have in 20.04. I’m at my wits end with this thing. Now I don’t know if it is an issue with me taking it on a train 200km or just Ubuntu being funky.
A: I have this issue also, but mine is not half as fancy as your Radeon. I suspect it is a bug. I added the oibaf PPA - https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers to mine and it helped a little. You can try it and see? (there are like 3-4 reboots and updates needed) I suspect a fix is incoming real soon.
Q: I get to see now what people are on about with Firefox snap, I had no issues, but when I launch it, mind you, not already open, I get: “ pending update of “firefox” snap close the app to avoid disruptions “ Like excuse me? The message would make sense if I were using it during an update, not on launch.
A: The internet is full of tutorials on how to replace the snap with a .deb, however, if you were fine with the way it was, simply close it and refresh the snap. Or, you could simply reboot.
Q: Hi, looking for a solution, I find only more issues like mine, without answers. I have an LG34WN650 monitor set up the way I want it. As soon as I unplug my laptop and plug it in again, all of my widgets have moved and need to be manually moved back into position. It is getting on my nerves. Why can’t Kubuntu remember my settings?
A: The problem is not Ubuntu, you will get the same issue in any OS. The problem is that monitor is WFHD (I think is the right term), so it has screen real estate outside that of your laptop screen. This means that to display your widgets on the laptop screen, they need to be moved. When you switch screens, the extra bit is “added” the screen is not “stretched” if that makes sense. It’s not a bug but a feature.
Q: Now don’t jump on me – I’m using Linux Lite on a core2Quad, not Ubuntu directly, but I’m sure this applies to Ubuntu as well. Catfish is like windows search, slow. Is there a way to speed it up? I have lots of PDF’s I need to search through, I group them by Architect or project or address and there are hundreds of each.
A: Just like Windows has Voidtools everything, Linux has Fsearch or Angry search. Use those instead for instant results. http://cboxdoerfer.github.io/fsearch/ or https://github.com/DoTheEvo/ANGRYsearch or if you want to search within files, try recoll: https://www.lesbonscomptes.com/recoll/index.html
Q: I had Ubuntu running in Virtualbox while I was testing it, but it had too many issues, so I deleted the VM. One small problem, all my downloads were on Ubuntu. How can I get it back?
A: You can try recovering the .VHD then attach it to an Ubuntu VM and see if you get your data back that way, but with dynamic virtual hard drives these days, I’d say re-download and save yourself the hassle, as they can be hyper finnicky causing recovery to take a long time.
Q: I’m not sure if you can help, but it seems Aseba (1.6.1) can’t run on Ubuntu 22.04. The error we get is: error, dependency not satisfiable: libqt4-sql-sqlite. Without it, the Thymio is basically a paperweight. I have researched the error, but have basically come up with nothing.
A: What if you run the version in the repo’s – 1.6.99? If that does not work, I’m afraid you will have to ask on the Thymio forum. Other than that you can try in a VM with older Ubuntu or even petition the snap maintainers to make you a snap.
Q: I tried LocoMalito’s excellent version of Endless Forms Most Beautiful, but I get this error: “error while loading shared libraries: libssl.so.1.0.0: cannot open shared object file: No such file or directory” From Ubuntu questions I reinstalled gir1.2 etc, to no avail, as there was nothing wrong with mine to begin with. Libssl is 1.1 on Ubuntu 22.04 and E: Package 'libssl1.0.0' has no installation candidate. This used to work on Ubuntu 14.04, so… I got a copy of libssl1.0.0_1.0.2n-1ubuntu5.9_amd64.deb, but it did not work, instead branching into a gtk3 error.
A: Beware of dodgy sites that offer .deb-files. Go to http://security.ubuntu.com/ubuntu/pool/main/o/openssl1.0/ and grab the 32-bit version and try again. I think the 64-bit version may be the issue, uninstall the 64-bit version first. The whole 32-bit subsystem is not needed. If all else fails, try the Lutris recipe version. (quick Google result)
Q: I’m running Xubuntu and suddenly it is taking twice as long to boot. Systemd-analyze blame put’s it squarely at the door of nmbd.service, that takes almost a minute to wake up. On top of that there is NetworkManager-wait-online.service that push it over a minute. What do these do and why is it taking so long. <removed>
A: The wait service does just that, it waits. It waits for the internet to be available, so it is nothing essential. The nmbd service is also not critical, you can mask them to see if it helps. Only remove them after rebooting a few times. You could also try preload, the effects of preload are not immediate and may add to the boot time, but should be good after about 10 reboots. The syntax is: sudo systemctl <disable/mask> nmbd.service
Q: Miner69er, [2022/05/01 01:14] I have a ghost line running across the bottom 10% of my screen I can’t seem to get rid of. Xubuntu 22.04 fresh upgrade. Disk Usage: 33/146GB (24%), Memory Usage: 2702/3825MB (70.64%). Could it be a setting in conky?
A: 9/10 it is a setting – Go to window manager tweaks → Composter and turn off “shadows under dock windows” and it will go away. (I did this on Manjaro and it should work on Ubuntu) If not, let me know.
Q: I have tried 3 times now to install Ubuntu as my box came with Windows, but it says I’m out of space? I tried Ubuntu 20.04 and 22.04 and Kubuntu 22.04 so far.
A: During the install there is an option for installing Ubuntu using the entire drive, if you just next, next, next, it installs them side-by-side every time. Linux does not assume you are an idiot, so you will have to read the messages from now on.
Q: Guys, I have a Matrox c420 display adapter in my low profile box, I run the Ubuntu drivers, but it does not find any Matrox drivers. There are older drivers on their website here, https://www.matrox.com/en/video/apps/drivers/graphics/download?id=667, but I don’t know the in’s or out’s.
A: As far as I know, those are actually ATI/AMD Radeon chips, so you should be good without installing the proprietary driver. Otherwise see above about adding the oibaf repository.
