This is the error report I am getting on every boot. Is there a way to fix this ?

This is how the window looks like

Do you have QT5 libs installed?

You can try to reinstall with Pacman -U

https://mega.nz/linux/MEGAsync/Arch_Extra/x86_64/megasync-x86_64.pkg.tar.zst

Exactly which pacman command will tell if I have QT5 libs installed ? So far I have learned how to install/remove packages & how to update the system.

You want me to download Megasync using that link you gave & then uninstall the currently installed megasync client which I got from AUR & then reinstall using the the downloaded package ?

4

pacman -Ql qt5-base | grep -i LibQt5Core

Basically yeah, install the package from mega and uninstall the aur one, it might fix your issue

I have a question. If I uninstall the AUR version & install the downloaded package will I receive updates ? I am asking this coz under Debian/Ubuntu if you install a .deb package like Google Chrome or the Mega client it automatically adds a (repo) line in /etc/apt/sources.list but as far as I know this is not possible under Arch. Since this is a network facing app security updates are important.

Afaik no auto updates.
It seems that you have qt5-base

7

I have Mega installed directly from their website and it adds a repo in your pacman.conf, so updates will come.
I have the same error now and then too, not on every reboot but once in a while.

I tend to ignore it.

  1. Try a different kernel (-hardened can be picky);
  2. Click the “Send report” button so the Megasync developers can fix the problem.

In that case there is no point in downloading Mega from their website & reinstalling it.

Yes I read quite a few topics where people have complained about stuff breaking due to the hardened kernel but for me security & privacy comes first. Despite this crash Mega is working as usual so I will just ignore the crash report. In case Mega becomes completely unusable I will choose a different cloud provider but frankly there is no way I want to abandon the hardened kernel.

I mean, you could report the crash to the developers so they know it’s happening and then might fix it. :man_shrugging:

I’m not adding a solution but sharing my experience with megasync. What I use is the megasync from the AUR (I think it’s maintained by mega according to the description). But I installed it while using the normal kernel. Once done I switched to the LTS kernel.

I’m yet to come across an error like that but never know. It might happen tomorrow to me (because that bad stuff happens to me when I say it didn’t happen :smiley: ).

Done. Thanks.
