flatpak question
by David 28 Sep '20

28 Sep '20

I get a message when trying to update flatpak $ flatpak update Looking for updates… Info: org.fedoraproject.Platform is end-of-life, with reason: Fedora 31 runtime is no longer supported. Nothing to do. $ I do not think a novice user of Linux is going to find it simple to use flatpaks. The runtime thing is still way over my head, and all the different hubs ( two ? ), and how to know which hub is better, flathub or Fedorahub. ( I hear somebody out there joking..... P***hub, silly ) While I have your attention, I spent about 5 hours playing with appimages, and posted something about that here a few days ago. I have not yet dived deep into the topic, but my initial experience is that appimages are not for newbies, in their present form. It was suggested to me to discuss such things elsewhere on the community blog. I attempted that, but it has been 3 days now, and my post there is still pending. Another similar post I made in the other suggested Fedora forum, did not reach my intended audience. So I will have to think of some other way to express my ideas or rants. Once I feel confident, in the topic I want to discuss, maybe I will make a YouTube video. I am not there yet. Today's update of Rawhide, went smoothly. A tiny change to the kernel. It is worth noting, that since the kernel is allegedly hovering around 27.8 million lines of code, that if one line gets changed, the user is probably not going to notice much difference, unless that particular thing was something they were hoping would improve. Much of the changes appear geared toward future hardware that has not even hit the market yet. Meaning, one of many reasons a novice Linux user should not use Rawhide, is that the changes that might break their system are unlikely to give them any kind of noticeable improvement in their own user experience. Some other updates today were that packages like dracut and criu were rebuilt from fc33 to fc34. Many packages at this early stage in fc34 development, are going to be identical to what is in the upcoming beta release of Fedora 33, for example, the package or client "gnumeric," is still fc33. I do not know yet what those package differences are or what all that entails, but it is on my list of things to learn. My current vague grasp of the topic is that the package is compiled ( or recompiled ? ), with a newer version of the newer version of the tools that are used to build the packages for fc34. One important characteric of Rawhide is that many of the most important system components are git-versions of that package, and the git-version was only updated from one that might have been a few days stale. A novice would never have any idea what any of that means, but I am trying to self-teach myself. And on a similar note, many important system files are "rc candidates" such as mesa and the kernel. I assume many other packages are identical to what is going to be in Fedora 33 Beta. For example, x.org files and at least half the dependencies or files that other packages require to run, are still fc33, at this early stage in fc34 history. All that is just my own observation, and irrelevant. I am just trying to learn the correct way to express things about Fedora and Rawhide. Another reason to discourage a novice from using Rawhide, is that much of the files that are often updated are files related to writing software or programming such as python, perl, rust, etc. Most people do not need the newer versions of those packages. I do plan to do an install of Fedora 33 on hardware in December, and live in that for a while. But I have not yet had a reason for myself to stop using Rawhide. One of the reasons that I stopped distro-hopping a year ago, is that the only thing I would gain from using some other distro like SparkyLinux, LInux Mint, Netrunner, or PopOS!, is just to see how those other distros modify or customize the theming of their packages, some of which seem to only just get renamed ( or rebadged ?? ) in those other lesser distros. And I always use my own wallpapers, so the tiny one-man distros that mainly just have fancy wallpapers, probably are not my cup of tea. On a related note, I will probably never try Cucumber Linux: https://cucumberlinux.com/about.php Good Day from Arcola, Texas USA. David Locklear novice user of Rawhide

Re: Reload kernel?
by J.Witvliet＠mindef.nl 28 Sep '20

Just another thought: I observed (totally different conditions), that the system became sluggish beyond usable. In most of those cases it was a lame dns-server that was to blame: active, but not resolving.

From the vmstat, all of the time is idle, you do not have any wait, generally if you have a disk having issues the iowait will go up, but you have zero. Also from vmstat, the system time is low. So the gui gets slow, a reboot clears it, does it clear up? You might want to include a messages file from +=5 minutes of the the issue happening. Weird kernel bugs causing kernel lock issues would produce this behavior, and would don't usually show on vmstat, but they can be seen in the messages file.

/var/btmp with ssh:nottyroot
by Michael D. Setzer II 27 Sep '20

27 Sep '20

Had one Fedora 32 machine that has the ssh port open. the /var/btmp file was showing a number of lines with the ssh:nottyroot line followed by various different IP addresses. Can stop the sshd service that the btmp file stops growing. Use to use denyhosts on systems, but it seems to have been removed. The old denyhost would add blocked ipaddresses to stop these sites? Know that root is not allowed to login ssh by default, so are these lines just saying attempts had been blocked. Have vsftpd setup to use passive ports, so blocking port 22 would not be a big deal. But just seeing the btmp file grow seems to show wasted bandwidth if not showing an issue. Is it an issue or not?? Thanks. +------------------------------------------------------------+ Michael D.

Scrolling using keyboard combos doesn't work in VT or multiuser mode
by Andre Robatino 26 Sep '20

26 Sep '20

I noticed recently that Shift+PageUp, Shift+PageDown, Ctrl+Shift+UpArrow, and Ctrl+Shift+DownArrow no longer work for scrolling up and down in a VT or in multiuser mode, even though they work fine in graphical mode, where ironically they're not really needed since there one can just use the scrollbar. I see this in F32, F33, and Rawhide. I've seen it in the latter two for the past week or two, don't know if it was introduced in F32 around the same time. Anyone know if this is a known bug, and if not, what component to file a bug against?

curl/timeout issue -- OFF TOPIC!
by bruce 26 Sep '20

26 Sep '20

Hi. List has been rather sparse today. I have a curl issue that I thought I'd toss out. Yes it's off topic, and yes I've posted to the curl list as well. The basic url operates within the browser the curl cmd generates a timeout (7) error. curl --verbose -L 'https://www.saddleback.edu/' -H 'User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:68.0) Gecko/20100101 Firefox/68.0' -H 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8' -H 'Accept-Language: en-US,en;q=0.5' --compressed -H 'Connection: keep-alive' --cookie-jar /crawl_tmp/a.lwp --cookie /crawl_tmp/a.lwp thoughts?? thanks

Suspend not working
by GianPiero Puccioni 25 Sep '20

25 Sep '20

Hi, a friend has a laptop Dell Inspiron 15 5000 Series 5593 and "suspend" when he closes the lid doesn't work anymore, as it doesn't get back and he has to reboot it. It did work a few months ago with kernel (he thinks) 5.10 or 11 but with newer kernels it doesn't, we updated the system to F32 (it was F31) but nothing changed. He uses KDE but weinstalled Gnome too and it was the same The video card: "Intel Corporation Iris Plus Graphics G1 (Ice Lake) (rev 07)" could be a change in driver? Weird thing is he just used a Live version of Ubuntu and it seems to work, is there a known difference between them? Searching the net I found that there is a problem with the "type" of suspend used (S3 or S2 or something) and to try to put the line "mem_sleep_default=deep" in the kernel line, no change... Any suggestions? I'd really hate see him switching to Ubuntu just for this.

Is this better ?
by David 25 Sep '20

25 Sep '20

https://communityblog.fedoraproject.org/?p=9285 I have never ever used Wordpress. I do not yet know if I followed all the Fedora procedures to do that. My first impression is that that entire procedure is going to scare off 100% of the enthusiastic Linux users that want to share ideas about Fedora. My concern with that blog thing, is that I am wanting to share my experience today with Fedora users and other enthusiast of Linux, that today for the very first time, I used Firejail and I using it now to use the appimage of yesterday's nightly build of Fedora 81.0, and I am doing it in Rawhide, and that all the effort create a blog, and someone might skim over it a month from now and not find any relevance to it. The other problem with blogging, is you have to be more careful with grammar and you can't misspeak about things. You can't tell people to go check out "Ferdora" in a blog. LOL ! Please email me privately, to mentor me in this new journey. David Locklear Arcola, Texas USA P.S. Fedora is all about security, but they want to know my latitude and longitude to be a formal contributor ??

Krita related / appimage related
by David 23 Sep '20

23 Sep '20

I have never ever used an appimage before until just now. Earlier today, I saw on Phoronix that Krita had a new beta version. So I went to their website, clicked on nightly build and could not find a beta, but did find an alpha. I downloaded the Linux version which was an appimage. I went to the Fedora Wiki about appimages and followed the 3 step guide to using appimages and was surprised how simple it was. Krita 4.4 alpha works nominally on Fedora. so if there is a beta somewhere, then I guess it would too. In order to try this new version of Krita, one must understand the basic file system layout in Fedora which in my case is: /david/Downloads/krita4.4.appimage use cd command in terminal to change to Downloads In my case, that was as simple as: $ cd Downloads next easy step ( after the $ in terminal ) type chmod +x krita-4.4.0-alpha-x86_64.appimage ( you can cut and paste the file name to simplify that, as it has some extra stuff in it ) Exit terminal, and go back to Files Just double-click on the Krita appimage file in Files afterwards. Please let me know if there is a simpler way. I imagine you might want to move it from Downloads directory to a temporary directory or an custom directory that you created for appimages ??

sort of Firefox related
by David 23 Sep '20

23 Sep '20

I did a new install of Rawhide a few days ago, and I just assumed that the Firefox version was the most recent or within a few weeks of the most recent. I was pondering the idea of playing with Gnome Boxes, and decided I would try to download an iso of some other distro. When I logged on to Manjaro website, it immediately gave me a large dialogue box that said "your browser Version 78 is out of date." So why could Fedora not tell me that ? Anyways, I removed version 78 ( the rpm version ) and installed the flatpak version, which is 80. I am not up to date on the general consensus of using flatpaks in September of 2020. I have no problem with flatpaks. Now I have to set up all my web-stuff settings again. Why would anybody want to use the rpm version of Firefox ? Limited resources on their computer ?? While on the subject of flatpaks, what are some of the upcoming flatpak apps to keep an eye out for ? What are flatpaks are way above their rpm counterparts in development ? Are future versions of Fedora ( 34, 35, etc. ) going to default to the flatpak version of Firefox ? My install of Rawhide has about 20 man-hours of usage, with no problems. I hope to do an install of 33 in a month or two. On an unrelated topic, the fans on my Radeon 5500XT, do not turn on except when booting up, but I have not tried to play a video game yet. Cheers, David Locklear
