I want to install "PlayOnLinux" on Ubuntu 18.04. I opened Software and Updates→Other Software→Add. Then I typed

deb http ://deb.playonlinux.com/ubuntu bionic main

but it shows some errors:

Error message details:

E:The repository 'https://dl.winehq.org/wine-builds/ubuntu ubuntu Release' does not have a Release file., 

W:Updating from such a repository can't be done securely, and is therefore disabled by default., 

W:See apt-secure(8) manpage for repository creation and user configuration details., 

W:An error occurred during the signature verification. The repository is not updated and the previous index files will be used. 

  GPG error: http://dl.google.com/linux/chrome/deb stable Release:

How do I solve these errors?

Although PlayOnLinux is already available in official repositories of Ubuntu which can be installed using:

sudo apt install playonlinux

But if you still want to install from PlayOnLinux's repository, here is what I observed.

After looking at the repository information for bionic availabe on official site, it looks like you added wrong repository (with extra "ubuntu"). Modify the repository you've added using "Edit" button after clicking on repository in Software and Updates→Other Software.

After that remove "ubuntu" from "URI" so that it looks like:

Now open a terminal and run:

sudo apt update

If you get an error like:

Err:1 http://deb.playonlinux.com bionic InRelease                              

  The following signatures couldn't be verified because the public key is not available: NO_PUBKEY <some key value>

Add that key using:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys <key value>

Then try sudo apt update again.

You don't need any external solution to play army men rts on ubuntu or linux in general, just use native steam.

"Steam, you say? but this doesn't solve the problem that this is a windows-only game!"

Actually, yes.

There's a difference between native and non native linux games.

All native linux games can be played on linux as is with steam and as it happens non native games can also be played on linux with steam but thanks to a steam option called "steam play" (which is pretty much essentially wine) that came out relatively recently.

it allows a simplifying of the whole thing. Installing a non linux game with steam comes down essentially to the same easy process you'd have under installing that same game natively, under windows.

So if you're willing to buy the game on steam then,

Simply install steam from : https://store.steampowered.com/about/

this will open up the software center, once it has finished loading, click "install" it will ask for your system password.

then once it is done installing steam, you can run it.

now you may log into steam.

then go into "File"-> "Preferences"-> last tab called "Steam Play", tick the box that says "enable steam play for all titles" then "Ok"

after this steam will ask to restart and after it does you will be able to install and play army men rts in the most hassle-free manner on linux.

If you wish you may play this game with lutris instead :

to do so install lutris (in a terminal) :

sudo add-apt-repository ppa:lutris-team/lutris -y && sudo apt-get update && sudo apt-get install lutris -y 

then you can run it from the start menu. Ideally connect a lutris account.

then go here :

https://lutris.net/games/league-of-legends/ (yes this is for league of legends but we won't be running league of legends with it)

click on the first "install" icon on the page. this should link to your Lutris (you must tell your browser to allow this, when it asks you.)

Let the installer start but when it starts downloading league of legens, close it.

Use the runspace it created, by right-click "browse files" drag and drop the army men rts inside that runspace then right click "execute with" find the install.exe and run it and it should install.

then once you're finished you can edit the rest of the League of legends runner to turn it into a army men rts runner, you must change the run file path to that or you army men rts exe and you can change the name and the icon also.

It looks like there may be a stray space in your command line.

deb http ://deb.playonlinux.com/ubuntu bionic main

Try removing the space immediately before the colon, like this:

deb http://deb.playonlinux.com/ubuntu bionic main
