--- Comment #2 from rosendoagustinay...@outlook.com --- Hi. Thanks for the quick response. 1. First of all, I want to update my... I don't know how you call it... my first comment. Apparently, the behavior is very erratic. Now, when I try to create the file, the wallpaper don't change and the file is not created (it didn't before either), but when I try for a second time it does, and it does it every time, I don't know when it start to fail. 2. I forgot to mention that I update every Sunday at the very least, and some days during the week when I can. This is because I don't want my computer to break on an update during the week. That's another thing I want to mention. I'm not able to customize the update schedule. I tried with software-properties-qt but it doesn't work. I would like the updates to be installed when I turn off the computer, but I wasn't able to get it work. I read a very long thread regarding offline updates (https://forum.kde.org/viewtopic.php?f=309&t=170775), and I mention my problem, but I didn't have a good response. 3. I was about to update when I had the problem, but I decided not to. On the next point I will give you some command outputs on the current status and I will wait for you to tell me when you have all the info you need before I do so. 4. Regarding your response, I follow the assistant to file the bug. Here's the sources list it created: cat /etc/apt/sources.list.d/org.kde.neon.com.ubuntu.ddebs.list deb http://ddebs.ubuntu.com focal main restricted universe multiverse deb http://ddebs.ubuntu.com focal-updates main restricted universe multiverse deb http://ddebs.ubuntu.com focal-proposed main restricted universe multiverse The debug symbols it installed pkcon search dbgsym | sed -n '/^Installed/p' Installed kio-dbgsym-5.98.0-0xneon+20.04+focal+release+build95.amd64 (installed:user_focal-focal-main) Installed libqt5core5a-dbgsym-5.15.5+p20.04+tunstable+git20220920.0042-0.amd64 (installed:user_focal-focal-main) Installed libqt5gui5-dbgsym-5.15.5+p20.04+tunstable+git20220920.0042-0.amd64 (installed:user_focal-focal-main) Installed libqt5widgets5-dbgsym-5.15.5+p20.04+tunstable+git20220920.0042-0.amd64 (installed:user_focal-focal-main) Installed ubuntu-dbgsym-keyring-2020.02.11.4.all (installed:ubuntu-focal-updates-main) Now, considering your answer, I follow a thread on askubuntu (https://askubuntu.com/questions/487222/how-to-install-debug-symbols-for-installed-packages) and add this line on the sources list: deb http://ddebs.ubuntu.com focal-security main restricted universe multiverse But when I try to update I get this error: sudo apt update [sudo] password for admin: Des:1 file:/var/lib/preinstalled-pool focal InRelease Ign:1 file:/var/lib/preinstalled-pool focal InRelease Des:2 file:/var/lib/preinstalled-pool focal Release [3.949 B] Des:2 file:/var/lib/preinstalled-pool focal Release [3.949 B] Des:4 http://security.ubuntu.com/ubuntu focal-security InRelease [114 kB] Ign:5 http://ddebs.ubuntu.com focal InRelease Obj:6 http://archive.ubuntu.com/ubuntu focal InRelease Des:7 http://archive.ubuntu.com/ubuntu focal-updates InRelease [114 kB] Obj:8 https://deb.librewolf.net focal InRelease Ign:9 http://ddebs.ubuntu.com focal-updates InRelease Ign:10 http://ddebs.ubuntu.com focal-proposed InRelease Ign:11 http://ddebs.ubuntu.com focal-security InRelease Des:12 http://ddebs.ubuntu.com focal Release [40,4 kB] Des:13 http://archive.neon.kde.org/user focal InRelease [162 kB] Des:15 http://ddebs.ubuntu.com focal-updates Release [40,5 kB] Obj:17 http://ddebs.ubuntu.com focal-proposed Release Err:18 http://ddebs.ubuntu.com focal-security Release 404 Not Found [IP: 2620:2d:4000:1::2b 80] Leyendo lista de paquetes... Hecho E: El repositorio «http://ddebs.ubuntu.com focal-security Release» no tiene un fichero de Publicación. N: No se puede actualizar de un repositorio como este de forma segura y por tanto está deshabilitado por omisión. N: Vea la página de manual apt-secure(8) para los detalles sobre la creación de repositorios y la configuración de usuarios. But I guess it's because I have to install the GPG key for the repositories. 5. This is the only uninstalled debug symbol that the assistant got behind. pkcon search kio-dbg Installed kio-dbgsym-5.98.0-0xneon+20.04+focal+release+build95.amd64 (installed:user_focal-focal-main) debug symbols for kio Available qml-module-org-kde-kio-dbgsym-5.98.0-0xneon+20.04+focal+release+build78.amd64 (user_focal-focal-main) debug symbols for qml-module-org-kde-kio Tell me if I have to install qml-module and give you all the backtrace again or install qml-module AND update the system and then give you the backtrace. 6. So, to summarize, I have to: 1. Install the GPG key for the repositories 2. Add deb http://ddebs.ubuntu.com focal-security main restricted universe multiverse to the sources list. 3. Install qml-module 4. Update the system Did I get right? Which steps do I have to follow and which ones don't? In what order? -- You are receiving this mail because: You are watching all bug changes.
