SUMMARY When I run Falkon as root everything is normal, but of course I can't do that. When I run as a user, it crashes. STEPS TO REPRODUCE 1. $ ./Falkon-3.0.1.AppImage 2. Could not find QtWebEngineProcess [17828:17828:0125/220226.413028:FATAL:zygote_host_impl_linux.cc(182)] Check failed: ReceiveFixedMessage(fds[0], kZygoteBootMessage, sizeof(kZygoteBootMessage), &boot_pid). #0 0x7f87429cc0a5 <unknown> #1 0x7f87429e1eca <unknown> #2 0x7f8742024fc3 <unknown> #3 0x7f8742023c3b <unknown> #4 0x7f8742024219 <unknown> #5 0x7f8741c6793a <unknown> #6 0x7f8741c6ce76 <unknown> #7 0x7f874178a600 <unknown> #8 0x7f874178bb25 <unknown> #9 0x7f874171fa61 QtWebEngineCore::BrowserContextAdapter::defaultContext() #10 0x7f87476d5218 QWebEngineProfile::defaultProfile() #11 0x7f8747a15e78 MainApplication::MainApplication() #12 0x00000040358d main #13 0x7f873c60f3d5 __libc_start_main #14 0x0000004038d5 <unknown> Received signal 6 #0 0x7f87429cc0a5 <unknown> #1 0x7f874170d141 <unknown> #2 0x7f87429cc43d <unknown> #3 0x7f873c623280 <unknown> #4 0x7f873c623207 __GI_raise #5 0x7f873c6248f8 __GI_abort #6 0x7f87429cbdc5 <unknown> #7 0x7f87429e21ed <unknown> #8 0x7f8742024fc3 <unknown> #9 0x7f8742023c3b <unknown> #10 0x7f8742024219 <unknown> #11 0x7f8741c6793a <unknown> #12 0x7f8741c6ce76 <unknown> #13 0x7f874178a600 <unknown> #14 0x7f874178bb25 <unknown> #15 0x7f874171fa61 QtWebEngineCore::BrowserContextAdapter::defaultContext() #16 0x7f87476d5218 QWebEngineProfile::defaultProfile() #17 0x7f8747a15e78 MainApplication::MainApplication() #18 0x00000040358d main #19 0x7f873c60f3d5 __libc_start_main #20 0x0000004038d5 <unknown> r8: 00007ffffa136e50 r9: 00007f873c741950 r10: 0000000000000008 r11: 0000000000000202 r12: 00007ffffa136c20 r13: 00000000000000ac r14: 00007ffffa136e50 r15: 00007ffffa1375c0 di: 00000000000045a4 si: 00000000000045a4 bp: 00007f873d1d8320 bx: 00007ffffa1373a0 dx: 0000000000000006 ax: 0000000000000000 cx: 00007f873c623207 sp: 00007ffffa136ab8 ip: 00007f873c623207 efl: 0000000000000202 cgf: 002b000000000033 erf: 0000000000000000 trp: 0000000000000000 msk: 0000000000000000 cr2: 0000000000000000 [end of stack trace] Calling _exit(1). Core file will not be generated. 3. $ OBSERVED RESULT Crashed EXPECTED RESULT Runned SOFTWARE/OS VERSIONS Linux: CentOS 7.6 KDE Plasma Version: KDE 4.14.8 KDE Frameworks Version: ? Qt Version: 5.9.2 ADDITIONAL INFORMATION
Please try with newer Qt, 5.9 is very old when it comes to QtWebEngine.
That's not possible. CentOS 7.6 comes from the latest stable RHEL. I can not put a stray newer release fundamental core function into this mission-critical production OS. Maybe Falkon is a non-starter for enterprise systems.
Funny that you think that a mission-critical production OS should keep at old software versions, while newer software versions have a multitude of security fixes. See for example the QtWebEngine security issues that were fixed in the Qt 5.9.6 -> 5.9.7 update alone: http://code.qt.io/cgit/qt/qtwebengine.git/tree/dist/changes-5.9.7/?h=v5.9.7
colony.three@protonmail.ch, That is pretty weird, because Appimage actually is built on CentOS and works and always was working fine to me on same system. Also your system Qt version does not metter, it uses built in Qt libraries. Make sure you have set right permission (1777) for /tmp directory! Also, I'm using self compiled verson of Falkon on my system for many years, and it also are well working.
