[krusader] [Bug 445549] kioslave5 blocking umount
https://bugs.kde.org/show_bug.cgi?id=445549 --- Comment #13 from Jim --- Given the lack of response, I'm assuming that this bug is not going to be addressed, so I began searching for a workaround on my own. It failed, but I wanted to document what I did and the results for anyone following this bug report or finding it in the future. I found that the kio packages are not flagged as being built for a specific version of ubuntu and that https://repo.miserver.it.umich.edu/ubuntu/pool/universe/ has the older (5.68) versions. First, I installed qml-module-org-kde-kio_5.92.0-0ubuntu1_amd64.deb in the hope that this behavior was simply due to a missing dependency not being installed. Unfortunately, the problem still existed, so I removed the package. I then installed kio-extras_19.12.3a-0ubuntu2_amd64.deb & kio-extras-data_19.12.3a-0ubuntu2_all.deb - dpkg complained of missing libopenexr24_2.3.0-6ubuntu0.5_amd64.deb so I downloaded & installed it. It then complained of missing libilmbase24_2.3.0-6build1_amd64.deb so I did the same for that package too. The problem still existed. I installed libkf5kiowidgets5_5.68.0-0ubuntu1_amd64.deb over version 5.92 that was on my system (installed by apt when the laptop was first set up). Krusader would not start - krusader: symbol lookup error: /lib/x86_64-linux-gnu/libKF5Parts.so.5: undefined symbol: _ZN3KIO13JobUiDelegateC1E6QFlagsIN14KJobUiDelegate4FlagEEP7QWidget when run from a command line. Figuring it needed the rest of the kio libraries, I installed these one at a time, testing between each: libkf5kiontlm5_5.68.0-0ubuntu1_amd64.deb - same error libkf5kiofilewidgets5_5.68.0-0ubuntu1_amd64.deb - same error libkf5kiogui5_5.68.0-0ubuntu1_amd64.deb - same error libkf5kiocore5_5.68.0-0ubuntu1_amd64.deb - different error this time - krusader: symbol lookup error: /lib/x86_64-linux-gnu/libKF5Parts.so.5: undefined symbol: _ZN3KIO11TransferJob13mimeTypeFoundEPNS_3JobERK7QString kio_5.68.0-0ubuntu1_amd64.deb - second error repeated itself Since krusader would still not start, I got to thinking that there are probably other dependencies out there, so queried apt & found that there are 104 (!!!) libkf5* packages on my system. Decided that I do not have the patience to go through the list, manually download each, and chase dependencies for every one of them. Removed libilmbase24 libopenexr24 kio-extras kio-extras-data with dpkg, then installed kio kio-extras kio-extras-data libkf5kiocore5 libkf5kiofilewidgets5 libkf5kiogui5 libkf5kiontml5 libkf5kiowidgets5 via apt to put my system back how it was, defect and all. :( --- Does anyone know of any programs that look / feel / behave like krusader that may not be affected by this flaw in the underlying KDE system? Or know of a viable workaround to fix the file locking issues introduced between 5.68 & 5.92? Love the program, but it's just plain broken at this point, especially with my using flash drives every single day. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=445549 jwag...@graffdeals.com changed: What|Removed |Added CC||jwag...@graffdeals.com --- Comment #12 from jwag...@graffdeals.com --- I've been plagued by this same flaw for a long time now, but really didn't have anything substantive to contribute until now. A system at work has Ubuntu 20.04 on it with Krusader 2.7.2-1. It does not have this problem. My home system has Ubuntu 22.04 on it with Krusader 2.7.2-1. It does have the issue. --- Here are the packages I have installed that match the pattern 'kio': kio-extras-data/jammy,jammy,now 4:21.12.3-0ubuntu1 all [installed,automatic] kio-extras/jammy,now 4:21.12.3-0ubuntu1 amd64 [installed,automatic] kio/jammy,now 5.92.0-0ubuntu1 amd64 [installed,automatic] libkf5kiocore5/jammy,now 5.92.0-0ubuntu1 amd64 [installed,automatic] libkf5kiofilewidgets5/jammy,now 5.92.0-0ubuntu1 amd64 [installed,automatic] libkf5kiogui5/jammy,now 5.92.0-0ubuntu1 amd64 [installed,automatic] libkf5kiontlm5/jammy,now 5.92.0-0ubuntu1 amd64 [installed,automatic] libkf5kiowidgets5/jammy,now 5.92.0-0ubuntu1 amd64 [installed,automatic] On the unaffected system at work, these are the versions of the above packages: kio-extras - 4.19.12.3a kio-extras-data - 4.19.12.3a kio - 5.68.6 libkf5kiocore5 - 5.68.0 libkf5kiofilewidgets5 - 5.68.0 libkf5kiogui5 - 5.68.0 libkf5kiontlm5 - 5.68.0 libkf5kiowidgets5 - 5.68.0 There is also a qml-module-org-kde-kio package at version 5.68.0 that is not installed on my home machine. --- Honestly, I do not know what most of these packages do or how they interact with one another, but it at least narrows down things a bit. Unfortunately, ubuntu does not like people installing old packages and so I cannot easily install old versions on my home machine to isolate it further. # apt list --all-versions kio Listing... Done kio/jammy,now 5.92.0-0ubuntu1 amd64 [installed,automatic] Is there a repository of .deb files with older versions of these kio libraries? If so, I'd be willing to play on my home laptop to figure out what version it was introduced in, though only if there's a reasonable chance of getting it fixed... this bug has been open for well over 2 years and there doesn't seem to be any activity on it. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=445549 --- Comment #10 from Hartmut --- This bug is reproducable: if I delete a file on a USB flash drive with Krusader and afterwards close that TAB in Krusader, then in 9 of 10 cases I cannot unmount this USB flash drive, because of kioslave5 is blocking this. Please fix. -- You are receiving this mail because: You are watching all bug changes.

So I always must close Krusader. This is very uncomfortable. Dolphin and Nautilus do NOT have this problem. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=445549 jmi...@atlas.cz changed: What|Removed |Added CC||jmi...@atlas.cz --- Comment #8 from jmi...@atlas.cz --- This has been happening to me for a very long time, possibly for years. I've been using Krusader on Manjaro with KDE Plasma and Linux Mint with Xfce. The same problem in both. When I use an external device while using Krusader, I often have to either close/restart Krusader or find and kill the kioslave5 process that blocks it (the former is usually quicker) if I want to unmount it. Even if I navigate to a different device in the Krusader tab which was displaying the contents of the device, even if I close the tab and there is no other tab showing the device, the device still cannot be unmounted. This never happens to me with any other software. Only with Krusader. For me, this is by far the most annoying, fundamental bug in Krusader. As for the comment by WiseLord, I can also confirm that the panels don't get updated properly. For example, if I have 10 files on an external device and delete all of them, the panel still often (not always) shows two, three or more files left. Only when I update the panel view (for example by going back and forward), it gets properly updated. I don't know of these 2 bugs are related. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=445549 --- Comment #7 from darek.pub...@gmail.com --- I can also confirm that copying the same files using Dolphin doesn't block unmount as it does under Krusader. So I can also confirm that it looks like this is Krusader-specific. -- You are receiving this mail because: You are watching all bug changes.

Removable media cannot be unmounted until Krusader is closed - then everything works normally. Very annoying. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=445549 WiseLord changed: What|Removed |Added CC||wiselord1...@gmail.com --- Comment #5 from WiseLord --- In my case something similar happens only when I delete some files from USB flash. Typical cases with USB flash drive: 1. Mount -> copy some files to the flash drive -> unmount => Everything is OK 2. Mount -> delete some files -> unmount => Fails because of kioslave5 uses it (can be seen with lsof) 3. Mount -> delete some file -> copy some files to the flash drive -> unmount => Also fails. Additionally, when new files are copied to the flash drive, the panel content is updated properly. But, when I delete some files, it's not updated until I press F5. I guess, the problem may be related to inotify when deleting files. Krusader doesn't receive a signal that files were deleted. Killing kioslave5 process allows to unmount the drive. Alternatively, restarting Krusader helps. With Dolphin everything works OK. It properly updates its visual representation of the folder when some files are deleted. -- You are receiving this mail because: You are watching all bug changes.

I am experiencing exactly the same behavior as reported above, plus I have problems with mounting flash drives. After reboot it works OK for limited time.
