when trying to update package listings via apt update or apt-get update I receive the following error:

E: Failed to fetch http://lt.archive.ubuntu.com/ubuntu/dists/xenial/universe/dep11/Components-amd64.yml.gz  Hash Sum mismatch
E: Failed to fetch http://lt.archive.ubuntu.com/ubuntu/dists/xenial/universe/dep11/icons-64x64.tar  Writing more data than expected (7468511 > 7467723) [IP: 193.219.61.87 80]

Is this somehow related to localised package distributor or is me all along? I am running beta2 release, that I've successfully installed and updated (without any error prompts) yesterday. Previously I used a 14.04 derivative which also did not bring up any errors. What can be the reason for this error?

EDIT: to duplicate markers, the topic name tackles a different problem rather than the hash sum problem, which is being referenced.

I decided to take part upon developing Ubuntu applications although I am having trouble finding projects to contribute in C, C++, C# and Java at Launchpad (not necessarily Launchpad alone). Can you offer several projects that are Ubuntu related?

I've tried installing Steam from Valve's website , although I had a persistent error when trying to start steam:

Installing breakpad exception handler for appid(steam)/version(1352224866_client)

I've so far tried the another askubuntu.com solved question with installing ia32-libs, although this didn't work. I'm pretty not sure what to do next to fix this problem.

I recently noticed that my Ubuntu 11.10 "window-grid" function is not working normally. It simply doesn't respond to my window drags to edges. I installed compizconfig-settings-manager and checked the settings on the grid option and it seems to be all set, although it's not working yet. How should I approach the problem?

I keep seeing the above image here on the Ask Ubuntu and I'm curious to know what Ubuntu Global Jam is.

I am searching for a tool (or maybe there's a workaround to get it accessed via default tools?) which would let me mount S60 (symbian) filesystems. So far I've found P3nfs, although it seems a bit outdated for current ubuntu (problems with some of gcc modules) or am I doing something in a wrong manner? Thank you in advance

it's been a while since I last used Ubuntu and it looks like that Ubuntu changed a lot. Some fast questions would be is current default (Ubuntu 11.10) panel still gnome-panel or is it unity-panel or so? I know that it is possible to integrate into messaging panel, although my program is not oriented towards messaging (imo neither is ubuntu one), it's a google task synchronizer. What is the way to add my program to clock panel? A subquestion (a little abstract, but don't know how to address) would be, how is the calendar applet made and what are the requirements to make such?
