It looks like you have enable your CD-rom as part of your sourcelist. You need to disable it. Open the terminal and type (or copy/paste): sudo nano '/etc/apt/sources.list' It should look like this: Set a # infront where it says deb cd-rom So it looks like this: # deb cdrom:[elementary OS 5.1 hera - stable amd64 (20191202)]/ bionic contrib main non-free ...

There is a new update in order to make not only fullscreen but also maximized applications to go to a new space automatically and there is a call for testing on another website. Probably because of this feature the option for switching on and off the dynamic workspaces is removed, I cannot say if it will be changed or not after the next updates, but for the ...

To translate that: 1. sudo open /etc/apt/apt.conf.d/50unattended-upgrades 2. remove one of the end quotation marks in line 13 "UbuntuESMApps:bionic-apps-security""; --> "UbuntuESMApps:bionic-apps-security"; save to test you can run sudo unattended-upgrades --dry-run -v

According to the announcement blog post: …if you’re on an existing Juno install and would like or need the improved hardware support, you can install it from Terminal with the following command: sudo apt install --install-recommends linux-generic-hwe-18.04 xserver-xorg-hwe-18.04

If you want to update elementary OS 5.0 to 5.1 you can use the classic manual method $ sudo apt update $ sudo apt upgrade $ sudo apt dist-upgrade $ sudo reboot check if you are in elementary OS 5.1 after reboot $ cat /etc/os-release NAME="elementary OS" VERSION="5.1 Hera" ID=elementary ID_LIKE=ubuntu PRETTY_NAME="elementary OS 5.1 Hera" LOGO=distributor-...

The tor-browser package in that ppa has not been updated in a very long time, I do not recommend using it. My suggestion is to remove that ppa, to get AppCenter working again, and then install tor from the ubuntu repository (as per the Tor Project's instructions). To remove the obsolete ppa: sudo add-apt-repository --remove ppa:webupd8team/tor-browser ...

The problem with rolling back to Juno (considering you take LinkPhoenix advice to reinstall Juno from scratch) is that Hera comes as an automatic update, so you wouldn't EVER be able to update anything on your system, or Hera would come along. Not sure this is what you want.


2

what I recommend you is to try to do this using command lines. Open your terminal application and execute flatpak update ! without sudo, otherwise you will receive an error message. Another option that works for me in a bit complicated situations is sudo flatpak repair.

Replace hera to bionic in the next files: /etc/apt/sources.list.d/appcenter.list /etc/apt/sources.list.d/patches.list /etc/apt/sources.list.d/elementary.list Use the following command to automate process: find /etc/apt -type f -print0 | sudo xargs -0 sed -i 's/hera/bionic/g'

flatpak update fixed it for me as well

There's also the /etc/apt/sources.list.d as well. Each file in that directory can contain other repositories your system will search. Check there to see if you're referencing an outdated repo.


1

The main repository file is /etc/apt/sources.list and the sources you add usually go there as lines or into /etc/apt/sources.list.d/ folder as *.list files. I do not know your linux and terminal skills but you can edit the above file using terminal. If you attempt to do this, do a backup of the file first, for example into your home folder with sudo cp /...

AppCenter doesn’t start downloading updates until you launch it. If you can just cancel the update before it actually begins or if you don’t approve the update, you can just not download and install it and save data... though launching the AppCenter itself might take up a bit of data on it’s own...

Okay, this is weird I just ran it again to get the error message and it has actually fixed my system now. Can anyone advise how it would suddenly fix itself. Literally haven't changed anything and the same commands that were throwing an error have now worked?? As said in your comments since it is fixed I would recommend installing LibreOffice from Flathub ...

I really don't advise doing this if it's just for the purpose of saving storage, but you can create a live USB of your distro of choice and then overwrite the partition that had your original install. This will not affect your new OS, but your old one will be completely removed. IMPORTANT NOTICE: FORMAT THE DRIVE BEFORE YOU INSTALL! THIS CAN AND WILL CAUSE ...

This was resolved in the comments on the question, posting answer here for posterity. The issue was a corrupt apt cache. The required version of plank comes from the elementary/os-patches repository, which we could see was correctly available on the system from the apt update output. Despite successful runs of apt update, running apt-cache policy plank was ...

Found this link in my searches: Error while doing 'sudo apt update': no Release file I was able to do apt upgrade. App-center still doesn't work Update edit appcenter, elementary and patches .list flies - remove any refrence to Hera / Juno to Bionic and save. Everything works.

I see a few errors. The important one is that it looks like you have some broken package lists files. In order to fix it, an option is to clear all files and recreate them again. To remove them you can execute into terminal sudo rm -rf /var/lib/apt/lists/* it will remove all package files and directories, it is important to have an asterick (*) at the end ...

I had the same issue today; I opened up Terminal and entered sudo apt update and then sudo apt upgrade. After that, I rebooted and the issue is gone.

trying to update my OS 0.4.1 to the latest version The ability to easily upgrade to the new version has only been introduced in elementary OS 5.0. I believe this was also the reason behind the version numbering shift. I don't whant to buy new license to download the 5.1 version. :) You do not need to buy a new licence. elementary OS is free and open ...

List the installed package. flatpak list I found the same package is installed. Uninstall that package. flatpak uninstall [Application ID] Update flatpak and it success. flatpak ...

@Travis So the conclusion is "No luck either though.". Actually it's my first time when I had update elementary os trouble. I think that elementary os creators should read elementaryos.stackexchange.com from time to time ;). Faltpak in their opinion is "the future for our AppCenter ecosystem".So I try to send them this link of troubles. Not so easy I'm ...

You have to update elementary-tweaks package also in order to work with Hera. When the update to Hera was released, elementary tweaks behave like you explain, but after a while it was updated also and now it works as before, only slingshot options for raws and columns are missing, because it was removed from the OS, only 5x3 grid is presented at the moment. ...

I use a Dell XPS 15 9560 with Integrated intel + GTX 1050. I've learn not to mess with other NVIDIA driver rather than what appears available in AppCenter. My recommendation to you would be the following: 1) Uninstall any NVIDIA thingy you might have in your system. 2) Completely update elementaryOS to the latest. 3) Check which Kernel version you're ...

It looks like you are using a non-standard (to elementary) GTK theme and or window controls. Revert to stock theme/controls and see if it behaves properly. I recently bumped up against this as well and had to change my custom css theme to work again. HTH

I think the easiest way to do that is to find the flatpak version of gimp and install it. https://www.flathub.org/apps/details/org.gimp.GIMP

It looks like the source list file for the brave browser is corrupted. You can remove it with sudo rm /etc/apt/sources.list.d/brave-browser-release-.list and try to install it again later.

So the solution was pretty simple. Just a matter of removing AppCenter: sudo apt remove appcenter and then reinstalling it sudo apt install appcenter Et viola, no more errors! I think it had something to do with reusing a /home partition from a previous elementary OS (and a few other distros too) install.
