Noticed something possibly relevant to this bug on the Lubuntu Users mailing list, posted by @Fritz:
Once again in Lu canât access Discourse, so posting here . . . running kinetic this morning and executed âapt update && apt dist-upgradeâ . . . showed a few hundred packages to install . . . midway through on #52??? there was a âhangâ on what might have been âinitrd - 5.15xxxxxâ and there was an âerrorâ showing in the update applet . . . something about âpackage number countâ??? Concurrently FireFox disappeared from the internet menu . . . .
I couldnât âctrl-câ out of the hang in the console . . . couldnât launch synaptic because âaptâ was locking access . . . didnât know the precise command to âforce quit aptâ . . . I also tried âapt -f installâ but that wouldnât override aptâs lock on the system. Finally just shut down out of it.
On cold boot in spite of hanging âhalfwayâ . . . now it showed only one package left to upgrade . . . a language package?? But it showed â5.15 xxxâ to be removed in âautoremoveâ?? so it was previously trying to install it and then changed its mind??
uname -r right now shows 5.13.0-16-generic . . . I didnât update grub via the master grub controller in another OS . . . to see if that would get the kernel closer to 6.15??? Running a multi-boot grub situation . . . . But there hasnât been this kind of âhangâ in running apt in Lu in quite some time . . . ??? something got sideways in the dist-upgrade in kinetic . . . .
Emphasis on the disappearing Firefox added by me. As to what all happened here, I have no clue (things seem quite a bit more broken than just the Firefox icon going missing), but the fact that we have yet another instance of Firefox appearing to vanish seems possibly useful for if we try to debug this issue in the future.
Just had Firefox vanish from the Application Menu again upon booting a fresh installation of the latest Lubuntu Kinetic with BTRFS. GNOME Boxes running on Ubuntu 22.04.1, EFI+Secure Boot enabled, 2 GiB RAM, 20 GiB disk space. Enabled auto-login during installation. Upon booting the freshly installed system, Firefox was not available in the Application Menu. Rebooting the VM made Firefox show up again (though I didnât try to launch it).
I hate race conditions. (EDIT: Wasnât actually a race condition this particular time, see below)
This also occurred on a bare metal installation - Kinetic daily 20220927.2
WOW NY41 â Int.Cel. J4125, 8GB, 128GB SSD,Intel UHD Graphics 600Dual Band WiFi,Ethernet,BT5.1
testcase: full disk, encryption, secure-EFI, internet, no-swap + Install using another language (Icelandic)
Will retest and see if I can reproduce this.
This might actually be unrelated, as Firefox is consistently not showing up when the Lubuntu Kinetic ISO is booted, or on the first boot of (at least some) installs of Lubuntu Kinetic. Also, waiting for a while will result in Firefox showing up, after a flurry of Snap-related activity finishes.
@leok reported and I commented on this bug: Bug #1991011 âsnaps not preseeded on Kinetic imagesâ : Bugs : snapd package : Ubuntu
Alright, turns out something deep in the guts of Ubuntuâs ISO builds decided to blow up and now Snap preseeding has been disabled so that the ISOs will build again. Thatâs why Firefox is taking a while to show up after booting the ISO and on the first boot of the installed system. Not normal behavior, but expected for now.
