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

    enter image description here

  • 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 06 '18 at 00:12
  • 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 06 '18 at 00:22
  • Alright, this is what I get: https://i.imgur.com/hx6MYfx.png – Jesús Jan 06 '18 at 00:30
  • 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 06 '18 at 00:36
  • Hey there, I actually got rid of the error by doing "sudo dpkg --configure -a" because that's what it said in the terminal. Now when I do "sudo apt update && sudo apt upgrade" the last terminal message says "0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.". Is it fixed? Thanks – Jesús Jan 06 '18 at 00:46
  • Yes, then it's probably fixed. Please take a look at karel's answer then. – Gunnar Hjalmarsson Jan 06 '18 at 00:48

  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 06 '18 at 00:53

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 05 '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 06 '18 at 00:01
  • When running the first command you sent, the following appeared in the terminal: https://i.imgur.com/y8bAWoN.png And when I ran the last command, I got the following: https://i.imgur.com/VHihaKD.png And also, I am now having the same issue with other apps like WPS Office – Jesús Jan 06 '18 at 00:09
  • @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 06 '18 at 00:15
  • From https://i.imgur.com/y8bAWoN.png it appears like these packages are blocking the installation: libc-ares2, libcrypto++6, libqt5core5a, libqt5svg5 You can either install them manually with apt, but this may also cause further dependeny issues. I'd give it a try though. Usually this happens, when an outdated version of a library should be installed. Often there is a PPA in place to solve that issue for everybody, but i did not find one for mega: however there is this question: https://askubuntu.com/questions/545299/how-do-i-install-the-mega-sync-client – noreabu Jan 06 '18 at 00:17
  • Actually @GunnarHjalmarsson was right, I accidentally downloaded the wrong file. I'm sorry. Thank you all because of your useful help. This question can be closed now (I would close it myself, but I don't know how to do it) – Jesús Jan 06 '18 at 00:20
