Recently searched for a newer version of Ubuntu - 17.04. At once, there appeared some strange prolems with him. I'm not a Linux spec, I installed it to teach it anyway; I ask. I do not know how to solve it. Now: I'm trying to install Sublime Text 3. Upgrading to Ubuntu (16.04.2 LTS) I installed it with:

$ sudo add-apt-repository ppa:webupd8team/sublime-text-3
$ sudo apt-get update
$ sudo apt-get install sublime-text-installer

Now when I use the same commands I get errors in the terminal. Here is the log:

dawid4157@lenovo:~$ sudo su root
[sudo] password for dawid4157:
root@lenovo:/home/dawid4157# sudo add-apt-repository ppa:webupd8team/sublime-text-3

Does anyone have any idea how to fix this? I have permission to opt directory as something.

  • Problem is with the server you download from not with Ubuntu or your setup. I can't reach "download.sublimetext.com" either (wget https://download.sublimetext.com/sublimehq-pub.gpg errors out)

  • So what should you do to install Sublime Text 3?

  • Wait for the server to come back alive?

Instead of using add-apt-repository, you can add the repository's address and key manually by performing the following commands in a root shell. b.t.w. when opening a root shell in Ubuntu or any other Debian based distribution, use the following command

sudo -s

and insert your root password at the prompt.

To add the repository manually, try the following

wget -qO - https://download.sublimetext.com/sublimehq-pub.gpg | sudo apt-key add -
echo "deb https://download.sublimetext.com/ apt/stable/" | sudo tee /etc/apt/sources.list.d/sublime-text.list
sudo apt-get update
sudo apt-get install sublime-text
  • works fine for me.

  • @Rinzwind Did not work. Same time. I give the log. Additionally, I noticed that I can not normally download from sublime-text page this

  • I can download each repository. The Atom was downloaded without problems.

After doing sudo add-apt-repository ppa:webupd8team/sublime-text-3

do rm -f /etc/apt/trusted.gpg as quickfix from here

then run:

sudo apt-get update
sudo apt-get install sublime-text

It will ask for confirmation to install it without verification. Once the Debian developers have debugged the problem the issue will be sorted soon.

  • Doing this may break other application updates that rely on gpg Jan 20, 2018 at 16:18
