libxml2.tcz.md5.txt FAILED

chattrhand:
Hello TinyCore Team,

it seems to be a small problem, but it could be something for security fans:
- Installed a tinycore USBStick from a CorePlus-9.0 CD, burning date 2018-03-03 No problem.
- I did all of the updates since using the AppBrowser, but not always checked the md5sum.
- Last month I accidentally found libxml2.tcz.md5.txt FAILED . Only this one.
I tried to use different repositories, but no difference,

No suspicious behaviour of the system, all seems ok. No panic, but could this be a backdoor?

greetings chattrhand

curaga:
Server-side it matches the extension. Could be usb-stick corruption, or something else. This is the sum I see (9.x x86):

Hi chattrhand
I just checked both x86 and x86_64 repos and both appear to be correct..

Maybe try removing and reinstalling libxml2.tcz.

chattrhand:
Hi Rick,

Success! Uninstalling libxml2 was not allowed because of dependencies.

Uninstalling firefox also removed libxml.tcz, so I had to use the palemoon browser instead.

Now I tried again to re-install firefox via firefox_getLatest.tcz and voila! libxml2.tcz seems to be ok.
(tried some restarts and tested it a bit wildly)

Btw. NoScript reactivated itself with no interaction. That's fine.

Thanks for your help!

I'd do

--- Code: ---rm -f /etc/sysconfig/tcedir/optional/libxml2.tcz*
tce-load -w libxml2

--- End code ---

If there are other extensions missing

--- Code: ---tce-audit fetchmissing

--- End code ---
