How To: Restart TeamViewer From The Terminal

In a previous article, I wrote about TeamViewer, and this article will teach you how to restart TeamViewer from the terminal. The reality is, I like TeamViewer quite a bit but it has a nasty habit of failing during the authentication step.

The only way to make it work, without visiting the device in person, is to restart it. I actually do this with SSH, but it’ll work in the terminal. So, you’re doing it from the terminal – you’re just doing it remotely and using SSH to do that.

Well, no… I have no idea how you’ll be doing it. After all, you might choose to do it locally – where this will also work. So, is it really from the terminal? Yes. It just depends on which terminal, I suppose!

Anyhow, this is just a short article. If you’re physically at the computer, why are you using TeamViewer?!? If you’re physically at the computer, you can just restart it with the GUI – or you can use the terminal. 

Restart TeamViewer From The Terminal:

So, if you’re at the device, just open the terminal. If you’re not at the device and TeamViewer isn’t authenticating, just connect to it with SSH. We’ll assume you’ve already set up SSH and know how to connect. If you don’t, then go back and read the SSH link in the 2nd paragraph. You need to use the following commands. 

To stop the TeamViewer service, run:

To restart the TeamViewer service, run:

If you want to just run one command, you can do that too! Just run:

The latter command is probably the easiest, and TeamViewer fails often enough for me to have taken the time to alias the restart command. As far as I can tell, there’s no rhyme or reason for it to no longer authenticate, but that’s what happens.

Closure:

As I use it often enough, I figure this is worth sharing with the world. It’s not a very long article, but it is indeed an article. Hopefully this helps someone who’s having similar authentication errors. As near as I can tell, just restarting the service fixes it and I’d say that the authentication fails every other day, sometimes more and sometimes less. Thanks for reading!

Quickly Reset Ubuntu’s Default Repositories

Is your software not updating? Are you getting repository errors when you try to upgrade? There’s a quick and easy way to reset the Ubuntu repositories to the defaults.

Ubuntu, like all Linux distros, uses repositories for distributing software. This provides a central location for curated, standardized software that’s almost certain to work on your system. These repositories are not just where you install software from, they’re also where you get your software updates.

If you want to see them in action manually, open your terminal and enter the following:

That will show you the system checking the repositories, updating your internal database of software and software versions. There aren’t a whole lot of defaults, so it’s usually a pretty quick process. If you’ve been adding PPAs or other repositories, it could take a while to get through the list.

Of course, if you see errors with that command then this might actually be the article you’re looking for! There are a variety of reasons why one might want to set the system back to the defaults, and it’s actually pretty easy once you know how.

Reset Ubuntu’s Repos

Like many articles and exercises, this one is gonna start with you cracking open your terminal. You should already know how to do that, but you can just use your keyboard and press CTRL + ALT + T.

Once you have that open, just go ahead and run this horribly destructive (I kid, I kid) command.

NOTE: That command could have a horrible outcome if you mess it up. Be sure to double-check it, or use copy/paste. If you screw this up, you can delete files that you really don’t want to delete. You have been warned!

That command will erase all the entries in your ‘sources.list’ file, technically deleting the file itself, which is not necessarily a good thing. Fortunately, it’s a necessary step and only the first step. The next step is also easy – and more or less mandatory.

Just run the following command:

Up should pop a window that looks a whole lot like this:

software properties
Note the lack of any selected repositories. The next step should be obvious.

There you go. You have a blank slate. Select from those four (or five, if you want the source code and have selected at least one other repository) and then click close. When you close it, the system will ask you if you want to update the database and you should agree, of course. You can also change the server from which you download, and most people pick a server that’s geographically close.

That’s it. That’s all it takes to reset your Ubuntu repositories to the defaults. There’s no wizardry involved. You’re simply removing one file and recreating it with the defaults. You could do it all with a file manager if you opened it as root, but the terminal is faster and easier.

A couple of people asked, so I’ve set it up so that you can donate to help fund the site. I’m not going to try to guilt you into donating. The site will remain online and continue to grow even without donations. Still, I had some interest and figured I’d add it as an option.
