Hello Ibiam,

Comparing browse.py in:
   
   - Github repository https://github.com/sugarlabs/browse-activity/
   - Debian Salsa repository https://salsa.debian.org/pkg-sugar-team/sugar-browse-activity/-/blob/master/browser.py
   - The installed activity at /usr/share/activities/browseactivity

The Github and Salsa versions have matching line numbers. Difference between the Github and installed versions:
--- bgit # browse.py in Github
+++ bdeb # installed browse.py

             open(os.path.join(path, src), 'w').writelines(lines)

Seems the only difference was the lines that was split into new lines have been concatenated to a single line.

 You might have to include it as a dependency for your next release as that's the latest versionthat Browse currently has, what doesn't sit well with me is the line difference,  I can't do any 
investigation at the moment but it'll be great if you took a look at the source code to confirm the linedifferences. Thanks.

 Hello Ibiam,The version of the browse-activity installed was 205-2.

Sorry for the late reply, temporarily away from home, I'm on a different system testing Sugar and internet bandwidth isn't very high. Should be back in a day or two.
Best,
Shaan

 Hello Ibiam,Installing the libglib2.0-dev package fixes the issue. I have also just found that this issue is mentioned in the browse-activity readme '' Unusually, Browse also depends on glib-compile-schemas tocompile a Gio.Settings schema. ''.
Online searches also return similar results, eg. :https://askubuntu.com/questions/204643/getting-missing-dependency-for-compilation-glib-compile-schemas 
 and https://askubuntu.com/questions/161739/why-does-launchpad-fail-to-find-glib-compile-schemas-while-building-for-ppa
I'm fairly certain that this is the correct fix, however, I have not found libglib2.0-dev as a dependency of Browse Activity for the earlier releases of Debian at https://packages.debian.org/search?keywords=sugar-browse-activity . So I do not know how this was handled in older releases or if it was handled at all. 
Best,Shaan

 Can you test to confirm if it's the problem?

Hello Ibiam,Great to know that the markdown formatted as html is more convenient.
I'm not entirely sure that the web activity issue is due to libglib2.0-dev no being present as a depenency but the error seems to be caused due to some header file missing that is fixed by installing that package.
I'll open the issues as you specified and test further.

Thanks for the update Shaan,
The error you shared in 2) happens in #840 like you said but the traceback in the logs is seen for the first timeand looks like it's a Python 3 port regression, kindly open an issue in sugar so it can be tracked.
Can you confirm that 3) is caused by libglib2.0-dev not listed as a dependency in the control file?
Could you open an issue for 4) in the write repo?

I find the markdown rendered as HTML convenient and most of it appears as plaintext in the devel archive,except the bullet points that start with a `-` above them.

I have tried to install sucrose on the standard Debian Live ISO (it has no Desktop Environment, only CLI) as there were some issues while trying to do so in the Debian Live (KDE Plasma) ISO:
   
   -    
Attempting to install sucrose v117-x after adding the unstable repositories to sources.list and setting the default release as stable by sudo apt install -t unstable sucrose causes 100’s of packages to be removed (Including all KDE applications, Firefox, Konsole, etc) and initiates the install of several 100 language packs for Firefox, LibreOffice, etc. 

   -    
Installing by setting the default release as unstable and sudo apt install sucrose causes the same issue above.

   -    
Setting default release as ‘stable’ and attempting to install using sudo apt install sucrose/unstable does not cause this issue but requires including all the dependencies with /unstable postfix (otherwise dependencies are fetched from the stable repo itself). This is very messy, the Desktop Environment and almost all useful preinstalled applications get wiped, some dependencies aren’t satisfied while testing Sugar after install. 


Install Debian Live Standard ISO
https://cdimage.debian.org/debian-cd/current-live/amd64/bt-hybrid/debian-live-10.4.0-amd64-standard.iso.torrent

Set default package repository to unstable
# /etc/apt/apt.conf.d/my-default-release
APT::Default-Release "unstable";

Update, Install gcc-8-base, sucrose 
sudo apt update
sudo apt install gcc-8-base # select 'yes' on the prompt
sudo apt install sucrose

Debian Live Standard doesn’t come with a Display Manager by default, install lightdm
sudo apt install lightdm

Reboot, select Sugar and log in.

On testing:

1) Sugar launches. Again most activities work without issues. Listed issues below.

2) Error in shell.log
1591278095.943871 ERROR dbus.proxies: Introspect error on :1.28:/org/laptop/Activity/376730b6f93a8aa9b2929c28e423b45b73f2b515: dbus.exceptions.DBusException: org.freedesktop.DBus.Error.NoReply: Message recipient disconnected from message bus without replying

^ Seems to be similar to Sugar issues #840 and #843

^ This occurred while using the other installation methods as well. It was fixed by installing libglib2.0-dev. This may be a packaging issue where ‘libglib2.0-dev’ is not specified as a dependency for the Web Activity?

4) Write Activity crashes when trying to move a table.

I’m trying to keep a log/executed snippets in markdown on a Github repository. Some files may not contain anything useful, just snippets for future reference. I’ll make it public after I clean it up a bit. 

I’ll post anything important through mail. I have used the ‘Markdown Here’ extension to render markdown as HTML. Let me know if you find this more convenient and I’ll have to check how this appears in the Sugar Devel Archive. If not suitable, I’ll revert back to markdown/plaintext.
