How do I solve dependencies for MEGAsync on Ubuntu 16.04?

Question

I've downloaded the MEGAsync's debian package and tried to install on Ubuntu 16.04 with:

sudo dpkg -i mega.deb

But it throws this error:

Selecting previously unselected package megasync.
(Reading database ... 204976 files and directories currently installed.)
Preparing to unpack megasync-xUbuntu_16.10_amd64.deb ...

 megasync depends on libqt5svg5 (>= 5.6.0~beta); however:
  Version of libqt5svg5:amd64 on system is 5.5.1-2build1.

Then I tried sudo apt -f install to try to fix these missing dependencies and got this:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Correcting dependencies... Done
The following packages will be REMOVED:
  megasync
0 upgraded, 0 newly installed, 1 to remove and 0 not upgraded.
1 not fully installed or removed.
After this operation, 8.368 kB disk space will be freed.
Do you want to continue? [Y/n]

How can I make it fix the dependencies and not remove MEGAsync?

Also tried sudo apt -y install ./megasync-xUbuntu_16.10_amd64.deb and got:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Note, selecting 'megasync' instead of './megasync-xUbuntu_16.10_amd64.deb'

Solution 1

You can simply double click the file via GUI after you have made it executable. This is the fastest and hassle free option you can choose, it lets the system handle the dependencies. If you insist on GUI solution use gdebi for installing which does the same. So in your situation, let sudo apt install -f remove it and then do the following.

# get the right package for your Ubuntu version 16.04 if this step fails 
# because you not have 'wget' installed do 'sudo apt install wget' and retry
wget https://mega.nz/linux/MEGAsync/xUbuntu_16.04/amd64/megasync-xUbuntu_16.04_amd64.deb
#update the package archives
sudo apt update
#if the next step tells you that gdebi is already installed skip to the line after that
sudo apt install gdebi
# installing it with gdebi
sudo gdebi megasync-xUbuntu_16.04_amd64.deb

This should install all the necessary dependencies and the package itself.

Solution 2

Download packages from official website: https://mega.co.nz/#sync!linux

Type:

sudo dpkg -i megasync-xUbuntu_20.04_amd64.deb

Note: version of package may vary

Then Type:

sudo apt-get -f install

Note: Allow and type 'y' to remove additional disk space

Now Type:

sudo dpkg -i megasync-xUbuntu_20.04_amd64.deb

Note: version of package may vary

Type megasync to launch application

Ubuntu 16.04 does not contain that new a libqt5core5a. packages.ubuntu.com/search?keywords=libqt5core5a

[s3voch7]

@muru is there a way to install this libqt5core5a ?

@karel All I wonder is why he did not download the package for 16.04 directly? mega.nz/linux/MEGAsync/xUbuntu_16.04/amd64/… this one should be tailored to fit the packages in his version of Ubuntu.

[s3voch7]

You're right @Videonauth, that's the problem, I'm using 16.04 and I've downloaded the 16.10 .deb, thanks for poiting it out, please answer as a normal reply so I can set it as resolved :-)

An explanation of what these commands do would be helpful :)
