SUMMARY Discover takes long time to fetch updates on my Arch Linux, sometimes ~5 minutes. STEPS TO REPRODUCE 1. open Discover 2. go to Update page 3. OBSERVED RESULT Discover gets stuck at "Fetching updates..." for a while, sometimes ~5 minutes. Output in Konsole says "took really long to fetch FlatpakBackend(0x55868698fc10)". EXPECTED RESULT fetch updates faster SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.22.90 KDE Frameworks Version: 5.87.0 Qt Version: 5.15.2 Graphics Platform: Wayland

I am unable to reproduce, it takes 2-5s, on archlinux as well. A bit of research would definitely be useful here.
(In reply to Aleix Pol from comment #3) > I am unable to reproduce, it takes 2-5s, on archlinux as well. A bit of > research would definitely be useful here. I'm on Neon and I get the same problem, it's not present on a live session though. Is there any command or log I can gather to help solving this issue?
I can also reproduce the problem in Neon , no snaps or flatpaks installed. The issue first appeared to me in Neon 5.23.1 , when tried to update to 5.23.2 As a workaround I removed snap and flatpak backends, working fine. I wonder why these sources simply cannot be disabled by untick , is it so much programing work ? Reinstalled backends, same issue. Disabled only flathub.org , fetching updates is working properly and not stucked. It's surely flatpak related. https://www.reddit.com/r/kde/comments/qdtdm3/anyone_else_having_problems_with_discover_since/

This is happening on Fedora 35 KDE as well. I installed Fedora hoping it wouldn't be a problem but the >bug started happening after adding the Flathub remote<. This confirms Laosom comment: "Disabled only flathub.org , fetching updates is working properly and not stucked." Without Flathub the bug doesn't happen. I should note Fedora is still on Plasma 5.22.5-2 and Gnome Software is unaffected by the issue. This must mean it's some kind of incompatibility with the Flathub remote and Discover, not the whole Flatpak backend.

@Patrick, do you have any disabled repositories?

For those who can't disable flatpackes due to having one or more installed, this post on Reddit (https://old.reddit.com/r/kde/comments/qdtdm3/anyone_else_having_problems_with_discover_since/hk74x02/) by u/danievdm solves that by renaming the flatpak-backed.so file. For Neon, it's located in /usr/lib/x86_64-linux-gnu/qt5/plugins/discover/. This leaves us with a working again Discover, but all Flatpacks will have to be manually checked and updated until this issue is fixed. This needs to be a critical importance rather than a HI normal, Discover is absolutely useless for those of us who use flatpaks.
If it was 100% reproducible, it absolutely would be, but it's not; it only seems to hit some people. I've got the Flatpak backend installed and in use and I don't suffer from this issue. Nevertheless the presence of 5 duplicates indicates that quite a lot of people are, so I'll raise the priority.

A possibly relevant merge request was started @ https://invent.kde.org/plasma/discover/-/merge_requests/213
I'd really appreciate it if someone who has this problem could test this patch.
I have just applied your patch to Arch Linux. Now Discover takes 1.5 minute to fetch updates and Konsole no longer says "took really long to fetch FlatpakBackend(0x55868698fc10)".
1.5 minutes is better than 5, but wow, that is still a long time!

I've run a few tests because I noticed a lot of write activity when opening Discover: run: sudo fatrace -t --filter=W | grep flatpak > flatpak.txt run: plasma-discover Results in flatpak.txt: OPENED: 12:33:33.608343 plasma-discover(832727): WO /home/user/.cache/flatpak/system-cache/summaries/flathub-x86_64-aab196438b75a2f8a4e557816729cab1b1cd2a48633c41482327a10773617f25.sub CLOSED: 12:36:50.990684 plasma-discover(832727): CW /home/user/.cache/flatpak/system-cache/summaries/flathub-x86_64-405c2d51103d91afa18ec6f0286cf90ea92130492e6dbafd10be9a784f302ed9.sub 00:03:17 writing to flatpack system. cat flatpak.txt | wc -l 26134 Writes in 3:17! flatpak update completes within seconds (at least if there are no updates). I now start Discover with this command: plasma-discover --backends packagekit-backend,kns-backend,snap-backend,fwupd-backend my current home drive is a regular HHD, but that would a serious concern for an SSD for someone who checks updates regularly. Hope that helps .
Whatever you did, last update has solved the problem for me... Now Discover is as fast in fetching updates as it has been before the problem occured for the first time...
Oh great! Prick, are you seeing the same thing in Neon Unstable?
My neon unstable was never affected by this bug. Currently Discover 5.23.4 takes 15 seconds to fetch updates on my Arch Linux and I always see this error in Konsole (mentioning a different package each time I open Discover): Transaction error: "vhba-module-dkms;20211218-1;x86_64;community: could not read or write the package" PackageKit::Transaction(0x564f5ef6d080) qml: message: vhba-module-dkms;20211218-1;x86_64;community: could not read or write the package

Kernel: 5.8.0-432102030405-generic x86_64 Distro: KDE neon 20.04 5.23 There are a few errors/warnings, but it didn't take long (I closed Discover when it said no updates).

I installed Neon Unstable on a Virtual Machine and here are the results: At first, it didn't want to load the apps with an appstream error (sorry, I don't remember it). Then I tried making Flatpak the default source. Upon restarting Discover it would prompt me to add Flathub. Pressing the button did nothing to me. Then I went into Discover's settings, removed FlatHub, and re-added it. Now, at least on a VM, it's working perfectly. It takes no time to load the Flatpak list, it's instant! ---- While I was writing this, I re-installed the same Neon image to see if I could find what that appstream error was, but for some reason now the experience was different. It gave me this error after a while trying to load Flatpaks for the first time (this error is different than the first one): "Error deploying appstream: Error moving file /var/lib/flatpak/appstream/flathub/x86_64/.1cbe9f93f6ab5938f2d7523e2db1b7107348e55eb8dc583308dc39123ccd943-W284E1: File exists" Then I restarted Discover and everything was working as intended. If someone else faces the same issue I can try making a new bug report, but what matters is that this bug seems to be fixed. When 5.24 stable hits I'll check again if everything is okay.
I am also seeing this issue. It does eventually clear, but after no less than a few minutes. I'm very new to Linux and unsure what info would help here. But this is my system: Operating System: Kubuntu 21.10 KDE Plasma Version: 5.23.5 KDE Frameworks Version: 5.90.0 Qt Version: 5.15.2 Kernel Version: 5.13.0-25-generic (64-bit) Graphics Platform: X11 Processors: 16 × AMD Ryzen 7 3700X 8-Core Processor Memory: 31,3 GiB of RAM Graphics Processor: AMD DIMGREY_CAVEFISH I do have flatpak as a repository: Flathub - dl.flathub.org
Updating the "appstream" libraries to 0.15.1 with the builds from https://koji.fedoraproject.org/koji/buildinfo?buildID=1880490 makes it work fine for me. SOFTWARE/OS VERSIONS Operating System: Fedora Workstation 35 KDE Plasma Version: 5.23.5 KDE Frameworks Version: 5.90.0 Qt Version: 5.15.2 Graphics Platform: X11
Patrick, is this also fixed for you with appstream 0.15.1 or later?

This bug persists on my system, but I can't reproduce consistently. Yesterday I clciked on the update notification shown after login, Discover opened and got stuck at 'fetching updates' for ~3 minutes. Then I restarted Discover and it shown the available updates instantly. SOFTWARE/OS VERSIIONS Operating System: Arch Linux KDE Plasma Version: 5.24.3 KDE Frameworks Version: 5.92.0 Qt Version: 5.15.3 Graphics Platform: Wayland
That sounds like it's a different issue. Can you file a new bug report for it? You can link it in the "See also" field.
*** Bug 375877 has been marked as a duplicate of this bug. ***
I still experience this in KDE neon running Plasma 5.24.5
1. Can you verify that you have Appstream 0.15.1? 2. If you run `plasma-discover --backends flatpak-backend`, is it still slow?
(In reply to Nate Graham from comment #36) > 1. Can you verify that you have Appstream 0.15.1? > 2. If you run `plasma-discover --backends flatpak-backend`, is it still slow? Yes, appstream is 0.15.1 Running plasma-discover --backends flatpak-backend is very fast. Perhaps I am wrong about the nature of the issue. Every so often Discover just sits around when the progress bar is near 100% and never finishes. Thanks, and my apologies if I mis-reported.
Yeah, sounds like it's not the same issue. When you encounter this issue, please launch discover with only one backend, going through all the individual backends one by one. You can see the list of backends with `plasma-discover --listbackends` Eventually you will find the stuck backend. Once you do, please file a new bug report about it.
I found this thread with same problem I'm having on Devuan Beowulf (Debian Buster). I tested as asked and for me the one that hangs (never went through) was: packagekit-backend The other one that worked fast (correct) was: kns-backend
> Devuan Beowulf (Debian Buster) You're using a very old version of Discover, and likely of AppStream too. It's fixed in newer versions of this software compared to what your distro offers.
