I will be presenting the process of upgrading using the apt command line tool.
So first update the apt repositories
sudo sed -i 's/saucy/trusty/' /etc/apt/sources.list
sudo sed -i 's/petra/qiana/' /etc/apt/sources.list
sudo sed -i 's/saucy/trusty/' /etc/apt/sources.list.d/official-package-repositories.list
sudo sed -i 's/petra/qiana/' /etc/apt/sources.list.d/official-package-repositories.list
Then make the system upgrade
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get upgrade
The apt manager will ask you for keeping various configuration files during the upgrade. I chose to replace them with the new ones.
Users of Linux Mint or other GNU/Linux distributions that use MATE Desktop environment have surely encountered this problem where xdg-open does not work properly.
This is most often seen when using Chromium browser and trying to open a downloaded file. Almost every time it fails to open the file with the right software. To fix this you have to fix xdg-open.
Here is a quick fix:
- Go to Menu > Terminal
- Enter gksu pluma /usr/bin/xdg-open
- Search for detectDE(), then above this line else DE=””, insert a new line:
elif [ x"$MATE_DESKTOP_SESSION_ID" != x"" ]; then DE=mate;
- Search for open_gnome(), then after the section of open_gnome() {…}, insert a new section:
open_mate()
{
if gvfs-open --help 2>/dev/null 1>&2; then
gvfs-open "$1"
else
mate-open "$1"
fi
if [ $? -eq 0 ]; then
exit_success
else
exit_failure_operation_failed
fi
}
- Search for this line case “$DE” in, and after this line, add a new section:
mate)
open_mate "$url"
;;
- Save the file and retry the download links.
