Since I switched to Ubuntu, I have been having tons of problems. This is only one of them.

The software manager seems to be unable to install deb files; For example, I have tried to install MegaSync from its .deb file, but when I click install, it looks like if it began loading and then the install button appears again as if it wasn't touched. Here's a GIF of what I'm talking about:


Doesn't even ask for my password, and of course, the software doesn't install. It's strange, because I could install Opera using a .deb file before.

Things I have tried;

  • To run sudo apt update in the terminal
  • Restart device

Any ideas?

EDIT: After another restart, I could install some apps; However, I am still unable to open/launch MEGASync.

EDIT 2: This is not a duplicate; Megasync is not the only not working deb, I am having some others that are not working, such as Gdebi and WPS Office.

    @GunnarHjalmarsson I don't think this is a duplicate of "How do I install the Mega Sync Client", since some other programs such as WPS Office and gdebi aren't working neither – Jesús Jan 6 '18 at 0:12
  • Possibly. But then you have messed up the package system somehow, and need help to fix that. To start with, can you please open a terminal window, run sudo apt update && sudo apt upgrade and let us know the complete output by editing your question. – Gunnar Hjalmarsson Jan 6 '18 at 0:22
  • Alright, this is what I get: i.imgur.com/hx6MYfx.png – Jesús Jan 6 '18 at 0:30
  • It's better to copy the output and paste it into the question. Anyway, the error message in the end might be a result of the failed installation attempt. So can you please run sudo apt purge megasync and then run sudo apt upgrade again to see if the error is gone. – Gunnar Hjalmarsson Jan 6 '18 at 0:36
  1. The error message in your comment says that dpkg was interrupted. First you must run the command sudo dpkg --configure -a in the terminal to correct this problem.

  2. You mistakenly downloaded megasync-xUbuntu_16.10_amd64.deb, however you are using Ubuntu 16.04, not 16.10, so download megasync-xUbuntu_16.04_amd64.deb for Ubuntu 16.04 instead.

  3. Then try to install the MegaSync .deb file again by changing to the directory that contains the Megasync .deb file that you downloaded (megasync-xUbuntu_16.04_amd64.deb) with cd and running this command:

    sudo apt install ./megasync-xUbuntu_16.04_amd64.deb  

    The advantage of this command over sudo dpkg -i megasync-xUbuntu_16.04_amd64.deb is that it automatically installs the package's dependencies along with the package.

  • Yes, those steps fixed everything. Thank you a lot to everyone! I am very happy with the support you provided. – Jesús Jan 6 '18 at 0:53

I experienced a similar issue and i was able to figure out the next step by entering a terminal and doing the installation manually with dpkg:

cd /home/user/dir/with/package/
sudo dpkg -i package.deb

In most cases i would recommend to use the package provided from the repositories or use an PPA to avoid this kind of conflice and any further conflicts it may cause.

  • Well, it seems like it did install the software, however, I am unable to open it... I already allowed executing the file as program, but still doesn't launch – Jesús Jan 5 '18 at 23:59
  • How do you execute it and what is the result? Is there an error message in the terminal? Did you try "dpkg --listfiles package.deb" to see where it did install its files? – noreabu Jan 6 '18 at 0:01
  • When running the first command you sent, the following appeared in the terminal: i.imgur.com/y8bAWoN.png And when I ran the last command, I got the following: i.imgur.com/VHihaKD.png And also, I am now having the same issue with other apps like WPS Office – Jesús Jan 6 '18 at 0:09
  • @Jesús: It looks like you downloaded the wrong .deb file. I understand that you are on Ubuntu 16.04, and hence it's the .deb for 16.04 - for your architecture (32 or 64 bit) - you should download and install. – Gunnar Hjalmarsson Jan 6 '18 at 0:15
