Checksum mismatch in deb package for .desktop files

11. joulukuuta 2020 klo 19.45
Sijainti: Vianhallintajärjestelmät: Github
Avainsanat: Debian, Ubuntu, VSCode

  • VSCode Version: 1.53.0
  • OS Version: Ubuntu Linux 20.04

Steps to Reproduce:

  1. install .deb package
  2. run debsums -s

Does this issue occur when all extensions are disabled?: Yes

I’d like to resurrect #37762: the checksums for .desktop files included in the .deb archive fail to pass post-install.

$ debsums -s code
debsums: changed file /usr/share/applications/code.desktop (from code package)
debsums: changed file /usr/share/applications/code-url-handler.desktop (from code package)

This happens because the postinst script calls desktop-file-install for the .desktop files, which adds an X-Desktop-File-Install-Version entry to them, and hence the checksums change.

I don’t know why the desktop-file-install call is there, as including the .desktop files in the deb archive is sufficient to have them installed (in their proper place under /usr/share/applications/), with the checksum intact.

I built the package with just those desktop-file-install calls removed (see below), after which the checksums pass post-install (with no other changes that I can see).

There’s also LP #1876157: Memtest86+ in Ubuntu 20.04 doesn’t work

While hardware fault and memtest bugs are possible, there’s also LP #1876157: Memtest86+ in Ubuntu 20.04 doesn’t work. So if the memtest you ran was from Ubuntu 20.04 images, try running memtest from Ubuntu 18.04 images.

build.sh uses bashisms, but shebangs /bin/sh

1.37.0 fails to build in my build environment (Ubuntu 18.04 in LXC) with this error:

ubuntu@mattermost-mobile:~/mattermost-mobile$ npm run build:android

> mattermost-mobile@1.37.0 build:android /home/ubuntu/mattermost-mobile
> ./scripts/build.sh apk

./scripts/build.sh: 3: ./scripts/build.sh: Syntax error: "(" unexpected

npm ERR! A complete log of this run can be found in:
npm ERR!     /home/ubuntu/.npm/_logs/2020-11-14T11_47_00_288Z-debug.log

The top of that file, build.sh, refers to /bin/sh, but on Ubuntu and Debian, /bin/sh has been Dash for quite a while, whereas build.sh seems to written for Bash (where function is a valid keyword):

ubuntu@mattermost-mobile:~/mattermost-mobile$ head scripts/build.sh 
#!/bin/sh

function execute() {
    cd fastlane && NODE_ENV=production bundle exec fastlane $1 $2
}

I suggest switching the shebang to #/bin/bash, or better yet, #!/usr/bin/env bash (for path-agnosticity). In my environment, using either one fixes the build.

Description textbox unfocused after click, have to click twice to start editing

9. marraskuuta 2020 klo 16.14
Sijainti: Vianhallintajärjestelmät: Github
Avainsanat: Apache, Chrome, Firefox, MongoDB, Snap, Ubuntu, Wayland, Wekan

Since recently, editing the description takes two clicks instead of just one. The first click turns the content into a textbox, but it remains unfocused until I click it again.

Issue

Server Setup Information:

  • Did you test in newest Wekan?: yes
  • For new Wekan install, did you configure root-url correctly so Wekan cards open correctly? yes
  • Wekan version: 4.49
  • Meteor version: 2.0-beta.4
  • Node version: 12.19.0
  • MongoDB version: 3.2.22
  • Operating System: Ubuntu 20.04
  • Deployment Method: snap
  • Http frontend if any: Apache
  • What webbrowser version are you using? Both Firefox 82.0.2 and Chrome 86.0.4240.183 equally affected.
  • If using Snap, what does show command sudo snap logs wekan.wekan? nothing

Problem description:
Sorry for not providing animation, as peek doesn’t support Wayland. The steps below should be sufficient though.

Steps to reproduce:

  1. Open a card
  2. Click on the description once

What I expect to happen:
For the description to have focus (i.e. cursor, to be able to type)

What happens instead:
The description textbox remains unfocused and I can not type into it

It seems to refer to to paths in the domain root, whereas my root-url has the path https://my-domain.com/kan. Not sure if that’s related to the issue or not.

Currently experiencing this. `lsof /var/lib/dpkg/lock` shows only ”focal” as holding the lock. The same ”focal” process is also eating up all of the CPU. No dpkg or apt processes are listed by `ps` either.

This is probably bug #1785354

My guess is this is due to bug #1785354: ”/etc/fstab: fs_passno is 0 for all file systems”. So yes, you should probably correct it.

I removed all but the Ubuntu extensions, rebooted and then reproduced the issue

Avainsanat: Gnome, Synaptic, Ubuntu

I removed all but Desktop Icons, Ubuntu AppIndicators and Ubuntu Dock, rebooted and then reproduced the issue. Luckily I’ve found one way to reproduce this, albeit somewhat convoluted and still a bit unreliable, involving Synaptic and window tiling. And as it doesn’t seem to trigger the issue when using another account, I’m now working through settings differences between the two in hopes of finding something crucial.

While doing so, I did discover that dconf-editor is similarly affected:

Looks like dconf-editor did not exit with FAILURE, but the dconf-editor window did disappear just as Gnome terminal’s did.

VLC does not exit after closing window

20. huhtikuuta 2020 klo 17.02
Sijainti: Vianhallintajärjestelmät: Launchpad
Avainsanat: Debian, Manjaro, Ubuntu, VLC, Wowza

Still present in 20.04 (Focal) with vlc 3.0.9.2-1, though here at least it seems to only affect some URLs, not all. When I view a stream from my local webcam, vlc -vvv in the terminal shows

main playlist debug: incoming request – stopping current input

as the final message, and does not exit (after closing the window; Ctrl-Q still works). But when streaming from Wowza’s RTSP test stream [1], vlc exits just fine after closing the window.

Debian bug 916595 [2] and related VLC ticket [3] mention disabling hardware acceleration as a workaround, but even so I was unable to make it work (i.e. exit properly).

Possibly related: Ubuntu bug #1847162. There’s also been discussion about the issue over on Manjaro forums [4].
