[Linux Station] Fatal Python error on update

Post by SleepyPrince » Sat Jul 23, 2016 12:26 am

I was trying to update my Linux Station Ubuntu today however I am getting
"Fatal Python error: getrandom() failed" when installing packages.

I tried searching on the internet and first thought it was due to Python3.5 and low entropy
So I installed haveged and entropy_avail now reports >3000
However the same error occurred and I am stuck
I tried resetting the Ubuntu but the problem is still there

Have the same problem. Two packets failed on update - python3.5 and python3.5-minimal.

Same here ...
Therefore I reverted to Python 5.2.1-10 to avoid any unpredictable behavior with setup
scripts called during package updates.

Thanks

Hi,

i searched INet for the following deb packages

Code: Select all

  libpython3.5_3.5.1-10_amd64.deb
  libpython3.5-minimal_3.5.1-10_amd64.deb
  libpython3.5-stdlib_3.5.1-10_amd64.deb
  python3.5_3.5.1-10_amd64.deb
  python3.5-minimal_3.5.1-10_amd64.deb


and after (manually) dowloading I installed it via command:

Code: Select all

sudo dpkg -i *.deb

gmo18t, did downloading and installing from other source solve the problem?
i dont want to reset the system again
i am currenly using apt-mark to hold off the update

edit: I think I get what you mean now
download the older version and install them manually to overwrite the one with problem
which is the same version as I got now with 3.5.2-16.01 held off

Yes right, i did overswrite the problematic version with the older 3.5.1-10.
Afterwards i also marked these packages as “HOLD“.

I've created an issue on python bug tracker.
https://bugs.python.org/issue27955

In the meantime, you can replace broken python 3.5.2 binary with the patched one.
Do this at your own risk!!

Code: Select all

$ sudo -i
root@ubuntu_1604:~# apt update && apt upgrade
...
Errors were encountered while processing:
 /var/cache/apt/archives/language-selector-gnome_0.165.4_all.deb
 /var/cache/apt/archives/language-selector-common_0.165.4_all.deb
 /var/cache/apt/archives/python3-uno_1%3a5.1.4-0ubuntu1_amd64.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

root@ubuntu_1604:~# mkdir deb && cd deb
root@ubuntu_1604:~/deb# wget "https://www.dropbox.com/s/rvrea63oue4brum/python3.5-minimal_3.5.2-2~16.01ubuntu1_amd64.deb"
root@ubuntu_1604:~/deb# ar vx python3.5-minimal_3.5.2-2~16.01ubuntu1_amd64.deb
root@ubuntu_1604:~/deb# tar xvfJ data.tar.xz
root@ubuntu_1604:~/deb# cp -p usr/bin/python3.5 /usr/bin
root@ubuntu_1604:~/deb# cp -p usr/bin/python3.5m /usr/bin
root@ubuntu_1604:~/deb# apt upgrade -f

If you want to build the package directly, use this patch file.
