I'm rolled back to 11.6. It works fine with one warning only:

kbuildsycoca5: command not found


Strange: There's the /usr/share/kservices5/ServiceMenus directory on your system, but you don't have kbuildsycoca5 available. Perhaps FFS should check for "/usr/bin/kbuildsycoca5" instead.

Are you using XIM? This warning is coming from wxWidgets:
https://www.wxwidgets.org/docs/faq/gtk/#why-entering-accented-letters-or-other-non-ascii-characters-doesnt-work

Cannot get process information. ENOENT: No such file or directory [getlogin]


Works in my LMDE3 Mint test system, so it doesn't seem to be a general issue. But FreeFileSync should probably not use getlogin() and check USER, SUDO_USER, and LOGNAME environment variables instead, just like the installer does.

I've just updated the official FFS 11.7 release. Let me know if this fixes all the issues for you.

Hello,
I can confirm that I had the same issues in Xubuntu 20.04. But now, the new version has fixed the problem.
Thanks.

Sorry for late answer.
I've checked updated FFS 11.7 installation. All works fine. Thanks!
XIM warning is not actual for me. I think, wxWidgets used by some installed software, but I'm not a Linux guru to waste time to search this problem. :)
Finally I've updated to FFS 11.8 without any warnings!
