[Touch-packages] [Bug 1854588] Re: gdebi-gtk calls pkexec inappropriately
Hi Alkis, You are absolutely correct. I just removed the firefox snap and installed it through the mozillateam PPA instead, and indeed, gdebi ends up parented by init when launched through Firefox's downloads, just like what I saw with Chrome, and the same issue is reproducible (my patch fixes it). So snap has been hiding the problem.

[Touch-packages] [Bug 1854588] Re: gdebi-gtk calls pkexec inappropriately
I take back what I said in my previous comment. This does still affect 23.04, at least with Ubuntu MATE and Chrome. It all depends on how the processes are parented, which changes based on how you launch Chrome. If I launch Chrome from the MATE menu, it gets parented to "systemd --user" and this problem doesn't occur. If I launch Chrome by clicking its icon in mate-panel, it gets parented to mate-panel instead, which follows a parenting chain of mate-session -> lightdm -> init. This difference also affects how gdebi ends up being parented when Chrome launches it from its downloads. gdebi ends up parented to init if I try to open a Chrome download from Chrome after I've launched Chrome from the panel, and this problem occurs. The same can be said about the "setsid gdebi-gtk package.deb" command. If I start MATE Terminal from the MATE menu and run that command, it works fine. If I start MATE Terminal from mate-panel and run the same command, it immediately exits and I get the "Refusing to render service to dead parents." message instead. I suspect this difference explains why some people haven't been able to reproduce this problem but others have. I will point out that Firefox, regardless of how it's launched, seems to not be affected anymore. gdebi always ends up parented by systemd when Firefox launches it. Clearly there is still value in fixing this in gdebi. I'll look into addressing Julian's feedback and resubmitting the fix. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to gdebi in Ubuntu. https://bugs.launchpad.net/bugs/1854588 Title: gdebi-gtk calls pkexec inappropriately Status in gdebi package in Ubuntu: Confirmed Bug description: Steps to reproduce: 1.

[Touch-packages] [Bug 1854588] Re: gdebi-gtk calls pkexec inappropriately
It appears that this bug no longer affects newer versions of Ubuntu. It's unclear to me exactly how this change happened, but in 23.04, running "setsid pkexec echo hello" for example no longer prints the "Refusing to render service to dead parents." message, and instead works correctly. The original reproduction steps with Firefox/Chrome also don't cause the problem anymore. The difference seems to be that when you run pkexec like that, it now gets parented to "systemd --user" in modern Ubuntu versions instead of init, so pkexec is no longer unhappy about it. I can still spend some time tweaking the merge request as per Julian's feedback if there is any chance that this would result in new builds of gdebi for the older affected versions like 20.04 and 22.04. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to gdebi in Ubuntu. https://bugs.launchpad.net/bugs/1854588 Title: gdebi-gtk calls pkexec inappropriately Status in gdebi package in Ubuntu: Confirmed Bug description: Steps to reproduce: 1.

Wow, thanks for responding so quickly! That's great to hear.

I finally found some time to look further into this, it appears to be an upstream problem with qtstyleplugins.

[Touch-packages] [Bug 1363723] [NEW] QTextEdit jumps to keyboard cursor when losing focus
Public bug reported: Ubuntu Version: Ubuntu 14.04.1 LTS libqt5gui5 version: 5.2.1+dfsg-1ubuntu14.2 I am running a stock install of Ubuntu 14.04.1, fully updated as of this writing. If you are using the ibus input method (chosen by default in Ubuntu), there is a problem that can cause QTextEdit to lose its scroll position when it loses focus. I first noticed this inside of Qt Creator but it actually affects all Qt 5 programs. Here are the steps to reproduce it: - Fill a QTextEdit (for example, a Qt Creator editor window) with enough text so that there is a scrollbar. - Make sure the text insertion cursor is at the bottom of the file. - With your mouse wheel, scroll up so that the text insertion cursor is no longer visible on-screen. - Now click on the containing window's title bar, or choose an item from a menu, or click on another widget in the window. Just something to cause focus to change. What I expect to happen: Nothing should happen to the QTextEdit's scroll position. It should stay where it is. What actually happens: The QTextEdit scrolls down so the text insertion cursor is visible, as if I had typed a character. This is actually a known bug in the ibus input method plugin (libibusplatforminputcontextplugin.so), which is installed as part of Ubuntu's libqt5gui5 package: https://bugreports.qt-project.org/browse/QTBUG-40755 A fix was committed upstream to the qtbase 5.4 branch: https://qt.gitorious.org/qt/qtbase/commit/e5f3a25253263b67f3f211d76ed76ddc2298916e I don't know about what the release schedule looks like for trusty and Qt, but I'd like to respectfully request that this patch somehow makes its way into 14.04 for my own sanity while working inside of Qt Creator. :-) ** Affects: qtbase-opensource-src (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to qtbase-opensource-src in Ubuntu. https://bugs.launchpad.net/bugs/1363723 Title: QTextEdit jumps to keyboard cursor when losing focus Status in “qtbase-opensource-src” package in Ubuntu: New Bug description: Ubuntu Version: Ubuntu 14.04.1 LTS libqt5gui5 version: 5.2.1+dfsg-1ubuntu14.2 I am running a stock install of Ubuntu 14.04.1, fully updated as of this writing.
