Megasync doesn't start

Question

Yesterday I installed MegaSync with the Nautilus extension and when I restarted the computer (running Ubuntu Desktop 15.04) the MegaSync app doesn't start at all.

I tried running megasync in the terminal and nothing, System Monitor does not see MegaSync running. What can I do?

What does exactly "nothing" mean? No output and goes back to the input line? Or it does not return to the line? Can you also post the output of `ps axu | grep megasync`? — dadexix86, Aug 31 '15 at 07:35
Nothing means that MegaSync doesn't start, I type in the terminal megasync and the machine automatically gives me back the command line. — J. Doe, Aug 31 '15 at 14:50
$ ps axu | grep megasync fer 14427 0.0 0.1 5756 1980 pts/3 S+ 15:52 0:00 grep --color=auto megasync That is what Terminal gives me back. — J. Doe, Aug 31 '15 at 14:52

Why "`sudo`"? Typing random command in your CLI can result in **serious** damage. Avoid typing commands if you don't know what they do and no one tells you so (and clearly you don't know what `ls` does, otherwise you would not have done it with `sudo`). BTW the problem is that that file is owned by `root`. Is not the case that you tried to run Mega with `sudo`, right?... — dadexix86, Sep 01 '15 at 22:21
Running programs with `sudo`, especially graphical programs, may lead to some major problems like this (wrong ownership of files, that might result in you not being able to log into your system *at all*!). If you really can't avoid messing around with higher privileges on your system, at least use `gksudo` to launch graphical programs. — dadexix86, Sep 01 '15 at 22:23
Just want to point the origin of your issue: initially you started MEGAsync as a root user (at this point it created directories and files using root as an owner) and then you try to launch MEGAsync as a normal user. — Paul, Oct 08 '15 at 16:37

The answer of dadexix86 doesn't work all the time. At first, I did what he proposed and it worked.

But later on, when the issue reappeared, I found that I had to delete/rename the megasync.lock file inside "~/.local/share/data/Mega Limited/MEGAsync/":

Doing that, it worked like a charm.

This worked for me like a charm on Linux Mint 19. It should be marked as correct answer. – overkill22 May 19 '19 at 15:36
Make sure there is no related process still running: `pgrep -af mega`. Eventually, kill them with `pkill`/`killall` – Pablo Bianchi Nov 03 '22 at 17:40

The problem is a wrong ownership of some files in the home directory.

Acquire again the property of all the files in that directory via

sudo chown -R $USER:$USER "/home/$USER/.local/share/data/Mega Limited"

Where $USER is an environment variable with your current username.
