MEGAsync QT segmentation fault

Hello,
I’m continuing this thread on the old forum here.
I’m still unable to run megasync. I’ve got the libraw problem that many had and could pass it with that command line:

$ megasync 
megasync: error while loading shared libraries: libraw.so.19: cannot open shared object file: No such file or directory
$ sudo ln -sf /usr/lib/libraw.so.20 /usr/lib/libraw.so.19

As a side note, I found that command and it gave me this result:

$ find /usr -name "libraw.*" 2> /dev/null
/usr/include/libraw/libraw.h
/usr/lib/libraw.so
/usr/lib/libraw.so.20.0.0
/usr/lib/pkgconfig/libraw.pc
/usr/lib/libraw.so.20
/usr/lib/libraw.so.19

Now I’m again stuck with this error:

$ megasync 
Setting QT_SCREEN_SCALE_FACTORS= "eDP-1=1"
Error unsetting QT_QPA_PLATFORMTHEME vble
Segmentation fault (core dumped)

And my etc/env is like that:

$ cat /etc/environment 
QT_QPA_PLATFORMTHEME="qt5ct"
EDITOR=/usr/bin/nano

Using QT5 software leads no problem for me, for example KeePassXC.
Thanks!

I had same problem – rebulding megasync solved it :slight_smile:

I’m glad it worked for you but I’ve got very strange result.

After rebuilding megasync this came again:

$ megasync 
Setting QT_SCREEN_SCALE_FACTORS= "eDP-1=1"
Error unsetting QT_QPA_PLATFORMTHEME vble
Segmentation fault (core dumped)

Then I removed the packages and built megasync-nopdfium. Launching it gave again the same error:

$ megasync 
Setting QT_SCREEN_SCALE_FACTORS= "eDP-1=1"
Error unsetting QT_QPA_PLATFORMTHEME vble
Segmentation fault (core dumped)

BUT THEN I don’t know how the icon appeared in the status bar and it started to synchronize. I was able the status window. Then I clicked on the MEGA icon in my dock and nothing happened. I went back to the status window and asked to see the transfers window and the app disappeared from the status bar. It crashed… Which makes me believe there must be a way to start the app…

I’m facing the same issue. Conky and MEGASync refuse to work for whatever reason. If you find the solution please update here.

Hi guys,
I haven’t read the original, but since I had the same problem I thought I’d add my experience.

I had megasync-git installed, and got the lib error after the update. Tried to reinstall, but I got a build error.

Then I removed megasync-git and installed megasync using yay.
Then megasync started with no problem.

This is what yay reports right now
