Problems could be using a out-of-date mirror (have you checked your mirror is up-to-date?
I am using the default "Software and Update" repository settings. No mirrors. http/https ports are not being stopped by firewall/proxy, but ports used to download software are being actively stopped thus your issue. I enabled UFW. I was able to download and install the Gnome extensions "cpufreq" and "NetSpeed". I can download software using APT in the terminal. If I open Ubuntu Software, I get the following message: "Unable to download firmware updates from "fwupd": failed to download https://cdn.fwupd.org/downloads/firmware.xml.gz: Cannot connect to the destination." These are support issues, and not bugs. You may be using a university/corporate internet service which restricts certain traffic etc, no details of which have been provided. Please provide more details. I am using regular home internet. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-software in Ubuntu. https://bugs.launchpad.net/bugs/1854912 Title: Installation stuck at 0% Status in gnome-software package in Ubuntu: New Bug description: 1) Ubuntu 19.10 2) 3.30.6-2ubuntu10.19.10.0 3) I searched for "Pinta" in Unbuntu Software. I clicked the installation button, I expected it to install. 4) The install got stuck at 0% for several minutes. I was able to load a webpage, so my internet connection was good. I cancelled the installation of Pinta. Launch and Remove buttons appeared. If I click the launch button, nothing happens. Pinta is listed on the install screen. If I click the Remove button, I get a removal confirmation message. If I click the Remove button, there is a "Unable to remove Pinta" notification. --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu8.2 Architecture: amd64 CurrentDesktop: ubuntu:GNOME DistroRelease: Ubuntu 19.10 InstallationDate: Installed on 2019-10-28 (36 days ago) InstallationMedia: Ubuntu 19.10 "Eoan Ermine" - Release amd64 (20191017) InstalledPlugins: gnome-software-plugin-flatpak N/A gnome-software-plugin-snap 3.30.6-2ubuntu10.19.10.0 Package: gnome-software 3.30.6-2ubuntu10.19.10.0 PackageArchitecture: amd64 ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_US.UTF-8 SHELL=/bin/bash ProcVersionSignature: Ubuntu 5.3.0-23.25-generic 5.3.7 Tags: wayland-session eoan Uname: Linux 5.3.0-23-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin lxd plugdev sambashare sudo _MarkForUpload: True To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-software/+bug/1854912/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
