[BUG DESCRIPTION]
/usr/sbin/update-firefox.sh, /usr/sbin/get-google-chrome.sh, and /usr/sbin/update-seamonkey.sh are scripts for updating Firefox, Chrome, and SeaMonkey, respectively, and these scripts have a bug in common.
Displaying 'Failed to install gtk3' in a dialog box, these scripts unexpectedly stop trying to install gtk3 due to this bug when some of gtk3-dependent packages need to be upgraded.
[BUG RE-PRODUCTION]
Anyone who would like to experience this bug can re-produce it by doing the following steps:
STEP 1: Download the ISO file of FatDog 8.12, which is NOT the latest version, and burn it onto a DVD/CDROM or a USB flash drive.
STEP 2: Boot your PC with 'Fatdog64 without savefile' option from the media created in STEP 1.
STEP 3: Click "Menu->Setup->Fatdog64 Control Panel->Third-party Software Installers" and several icons are displayed in a window.
STEP 4: Double-click any one of the icons whose labels are 'Update Seamonkey', 'Update Firefox', and 'Get Google Chrome' to update the corresponding web browser. Then the 'Failed to install gtk3' dialog box appears.
[A PROMISING SOLUTION TO THE BUG]
Code: Select all
sed -i 's/slapt-get --install /slapt-get --no-prompt --install /' /usr/sbin/{update-firefox.sh,get-google-chrome.sh,update-seamonkey.sh}
# Beware that there is a space following '--install'.
[EXPLANATION OF THE SOLUTION]
Basically, the web browser updating scripts, /usr/sbin/{update-firefox.sh,get-google-chrome.sh,update-seamonkey.sh}, run the following 2 commands to install gtk3 before updating its corresponding web browser.
COMMAND 1: slapt-get --update
COMMAND 2: slapt-get --install gtk3
The source code of slapt-get v0.11.3 reveals that running slapt-get without '--no-prompt' option to install a package will display 'Do you want to continue? [y/N]' and wait for input from stdin when some of the dependent packages of the package to be installed need to be upgraded. Furthermore, the source code of slapt-get v0.11.3 also reveals that 'Do you want to continue? [y/N]' prompt always fails to get 'y', causing the exit status code to be non-zero, when slapt-get is run without a TTY.
If you run COMMAND 1 and COMMAND 2 in a terminal, like urxvt, of Fatdog64 8.12, 'Do you want to continue? [y/N]' is displayed and input from stdin is expected. Please refer to the following lines for details.
Code: Select all
# slapt-get --update

The following NEW packages will be installed:
at-spi2-core at-spi2-atk gobject-introspection gsettings-desktop-schemas
glib-networking libsoup librest libwayland gtk3
The following packages will be upgraded:
atk2
1 upgraded, 0 reinstalled, 9 newly installed, 0 to remove, 0 not upgraded.
Need to get 13.4MB of archives.
After unpacking 94.5MB of additional disk space will be used.
Do you want to continue? [y/N]
However, if you follow the steps described in [BUG RE-PRODUCTION], the web browser updating script is run without a TTY and so is COMMAND 2. In such situation, COMMAND 2 fails, causing the web browser updating script to show 'Failed to install gtk3' dialog box.
To sum up, a promising solution to this bug is using '--no-prompt' option of slapt-get to suppress the prompting function.
[NOTE]
Using Fatdog64 8.12 to demonstrating this bug does NOT imply that this bug exists in Fatdog64 8.12 only. In fact, this bug also exists in Fatdog64 8.13, the latest version.
