PPAs are inherently unsafe. By adding a PPA, you are giving a 3rd party the ability to distribute/replace any package (including important security-related system packages), and consequently the equivalent of administrator privileges. You should only add PPAs of developers you know to be trustworthy. That said, theoretically PPAs that target Ubuntu 14.04 (...

You're in the right track on installation of Flatpak on Elementary as indicated on their guide. You might not be aware of it, but add-apt-repository is disabled by default on Elementary (to avoid reckless installation of PPAs).

PPA (Personal Package Archive) are used to include a specific software to elementary OS. Note that sometimes Ubuntu ppas can break things, but this is rare. The "safeness" of a PPA depends mostly on 3 things: Who made the PPA - An official PPA from WINE or LibreOffice like ppa:libreoffice/ppa compared to a PPA that I created myself are not the same. You do ...

The possible fix: sudo apt-get install gksu # If not installed sudo apt-get install libcanberra-gtk-module:i386 # If you get Failed to load module "canberra-gtk-module" error Now gksudo nano /etc/lsb-release The file should be like, DISTRIB_ID="elementary OS" DISTRIB_RELEASE=0.3.1 DISTRIB_CODENAME=freya DISTRIB_DESCRIPTION="elementary OS Freya" ...

The problem comes after installing some certificates, and did not resolve when I removed them, not even using sudo apt-get install --reinstall ca-certificates or sudo dpkg-reconfigure ca-certificates. The solution I found was to completely remove the ca-certificates package and install it again, instead of using --reinstall. sudo apt remove --purge ca-...

The fact that there is no distinguishable difference between installing software through trusted repositories, such as the main repository, and then installing software through a PPA (GUI and CLI) The main benefit you may get is, latest and up to date packages.

The only way to be absolutely certain is by reading the code and checking if it is not malicious. If you can't read code or don't have the time to do so (almost no one does :p) you can verify how safe it is by: Use a search engine to get more information about the ppa. Check if there are articles describing the ppa (if a ppa has a lot of hype around ...

Since the currently supported version of elementary OS (0.3 Freya) is based upon the current LTS version of Ubuntu (14.04)*, anything that works with Trusty should work just fine in elementary. So, any app that has a PPA dedicated to Trusty on Launchpad should work as expected. Note that the hardware stack in 0.3.1 was actually based upon 15.04

As you can see there is a conflict between two packages (appstream-data-pantheon and appstream-data-pantheon-loki-stable) that both want to install a file (/usr/share/app-info/yaml/pantheon_xenial-main_amd64.yml.gz). You can try to (in this order, preferably): wait for the bug to be corrected :) remove the older package if you do not need it any more sudo ...

I have it on good authority from within elementary that no repository should ever contain luna, freya, or loki. If your sources.list ever contained that, they were incorrect, and should be changed to precise, trusty, and wily respectively. As for the changes to the repositories, those are likely unrelated changes to the build structure, and nothing to do ...

i fixed it by removing armhf using dpkg and restoring my apt directory by copying the entire folder from clean install media.

So, I was looking in the wrong path. The file I needed to edit was /etc/apt/sources.list. I just replaced loki to xenial and it worked.

That means you added a PPA that doesn't work with the current version of elementary. To delete it do sudo add-apt-repository --remove ppa:mpstark/elementary-tweaks-daily

Error 521 on the Host (https://packages.elementary.io)! Just wait, the error will be fixed soon

You probably have conflicting PPAs on your setup. Remove all the unnecessary ones and try again. If you really need the PPAs, add them one by one and apt update again then weed out those that cause conflicts.

It looks like one of the ppa .list files in the /etc/apt/sources.list.d/ directory may have a typo and instead of an "http" reference it has "ht*p". I'd check the files in that directory for the typo...

I'm working on a XPS 15 (with Skylake cpu) for a month now, Elementary OS works great even with the high DPI screen. When I run into trouble I usually search on "ubuntu" (for example "ubuntu dell xps 13") since most of it applies to Elementary OS. You can also find a lot of information on bugs etc on the Elementary Launchpad pages: https://launchpad.net/...
