As per title.

Tried to open the software boutique. Nothing opened, then some several second later an error was reported.

So, tried to open it from a terminal. Got the following output/error:

[i18n] Using en_GB
Traceback (most recent call last):
  File "/usr/bin/ubuntu-mate-welcome", line 2846, in <module>

[Network Test] Successfully pinged 'http://archive.ubuntu.com/'

Next, tried run apt-get update: got the following error:

Reading package lists... Error!
E: Encountered a section with no Package: header
E: Problem with MergeList /var/lib/apt/lists/dl.google.com_linux_chrome_deb_dists_stable_main_binary-amd64_Packages

Anybody any ideas?

Erm…slightly more serious now

Tried to run:

sudo apt-get install -f

Got this error:

E: Encountered a section with no Package: header
E: Problem with MergeList /var/lib/apt/lists/dl.google.com_linux_chrome_deb_dists_stable_main_binary-amd64_Packages
E: The package lists or status file could not be parsed or opened.

Tried to open synaptic. Got the similar error and it was forced to close.

Looking at the error, it seems to be something wrong with Google Chrome. So, tried:

sudo apt-get remove google-chrome-stable

Also:

sudo apt-get purge google-chrome-stable

Same error:

So, now completely stuck for updating and installing software

In a terminal try the following:

sudo dpkg --configure -a
sudo apt-get clean
sudo apt-get autoclean
sudo apt-get update

And try again. If that doesn’t work, try:

sudo rm /var/lib/apt/lists/* -vf
sudo apt-get update

And try again…

If that doesn’t work, well… I don’t know :wink:

Okay, seemed to have fixed it I think:

Opened, with caja as an administrator:

/var/lib/apt/lists

Deleted the following files:

dl.google.com_linux_chrome_deb_dists_stable_main_binary-amd64_Packages
dl.google.com_linux_chrome_deb_dists_stable_main_binary-amd64_Packages.diff_Index
dl.google.com_linux_chrome_deb_dists_stable_Release.gpg

Then went back to terminal and ran:

sudo-apt-get update

It completed successfully and also repopulated the 3 files, listed above, in the /var/lib/apt/lists folder.

Have also tried to open software boutique again and it opened immediately

No idea what i have done or how it has fixed it. But it seems to have.

Tried the first 4 of those, got the same error. But seemed to have fixed it. See immediately previous post

Great to hear. :slight_smile: To be more informative in future, I’ll be sure to add a check so a warning is displayed if Welcome/Boutique cannot be started because of an Apt problem.
