Have tried to download the latest version from the website and when I try to open the application to install in Ubuntu I get: ``` File type Debian package (application/x-deb) is not supported ``` How do I get around this? ---

Try to install Dropbox from [Install - Dropbox](https://www.dropbox.com/install?os=lnx) and let me know if it works. ---

That means you have some deeper issue in your Ubuntu. You basically can’t install any DEB package from any software vendor so this is not really a Manager issue. Try to use `gdebi` to install your .deb files. ``` sudo apt-get install gdebi ``` and then right click on your downloaded `Manager.deb` file and open with `gdebi` ---

In my Ubuntu, the file association got trashed and the system opens .deb files with the wrong application. As a work-around I do the following: 1. Close **Manager** if it is currently open 2. Open **FireFox** 3. Type **[Download | Manager](http://www.manager.io/desktop/download)** in the address bar, then press ENTER 4. Click **download** button, click **Save file** , click **OK** 5. When the download completes, click the green arrow in the FireFox toolbar 6. **Right-Click** the most recent **Manager.deb** file (it should be the first item in the list) If you downloaded more than copy of Manager the most recent file shows as **Manager(?).deb** where the **?** is replaced with a number. The most recent download will have the largest number. 7. Select **Open containing folder** from the context menu. The file you selected will be highlighted in the window that opens. (You may need to close or minimize FireFox to see the file window.) 8. **Right-click** the highlighted Manager file and select **Open with Ubuntu Software Center** on the context menu. 9. Wait for Manager to apper in the Software Center menu. Click on the **Update** button at the far right side of the Software Center window. 10. If a window opens asking for a password to install files, type your password then press Enter 11. When a **green check mark** appears under the Manager icon in the Software Center window you may close the Software Center and start Manager as you normally do. 12. Click on **About Manager** to verify the version of Manager that opens. The version number should match the number you see below **Ubuntu** in FireFox. ---

Could you run these two commands before installing Manager? See if it resolves the issue: ``` sudo apt-get update sudo apt-get install libmono-system-web2.0-cil ``` ---

> [@lubos](#): > > sudo apt-get install libmono-system-web2.0-cil Get the same error, here is the full explanation returned: ``` Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: libmono-system-web2.0-cil : Depends: mono-runtime (< 3.12.2) but 4.0.1.44-0xamarin1 is to be installed ``` ---

Try ``` sudo apt-get install mono-runtime ``` then try to install Manager again. For the record, I’m unable to reproduce this issue on Ubuntu 14.04 LTS so far. ---

I already have the latest runtime, probably there’s a conflict because I use to program with Visual Studio Code for Linux and during installation installed some libraries and remove others from the mono dependencies which conflicts with them. It keeps asking to install dependencies and to downgrade mono-runtime, I will test this in the other Linux box I have. ---
