package libgettextpo0 0.18.1.1-5ubuntu3 failed to install/upgrade: erreur lors de l'écriture de « <sortie standard> »: Success

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

You've got multiple segmentation violation errors in your system logs; this many of them for seemingly random programs makes me think you may have corrupted data on your hard drive or failing memory or other hardware issues.

Run debsums -as (as root) to see if program files are known to be corrupted.

Run memtest86 or memtest86+ overnight to see if your memory is bad. (A clean run overnight isn't proof that things are alright, but failures mean you have problems that need to be resolved.)

Thanks
