Vine o vreme când apar surprize cauzate de actualizări și în zona Debian / Ubuntu.

Cea mai recentă surpriză este eroarea de genul:

relocation error /usr/lib/x86_64-linux-gnu/libgnutls.so.30: symbol _idn2_punycode_decode version IDN2_0.0.0 not defined in file libidn2.so.0 with link time reference

De la asta, module din apache2.4 nu vor mai vrea să funcționeze (modsecurity2 fiind unul dintre ele), curl (și librăriile php-curl) și încă câteva.

În majoritatea cazurilor de azi-noapte încoace m-am lovit de astfel de erori:

/usr/lib/apt/methods/http: relocation error: /usr/lib/x86_64-linux-gnu/libgnutls.so.30: symbol _idn2_punycode_decode version IDN2_0.0.0 not defined in file libidn2.so.0 with link time reference /usr/lib/apt/methods/http: relocation error: /usr/lib/x86_64-linux-gnu/libgnutls.so.30: symbol _idn2_punycode_decode version IDN2_0.0.0 not defined in file libidn2.so.0 with link time reference /usr/lib/apt/methods/http: relocation error: /usr/lib/x86_64-linux-gnu/libgnutls.so.30: symbol _idn2_punycode_decode version IDN2_0.0.0 not defined in file libidn2.so.0 with link time reference /usr/lib/apt/methods/http: relocation error: /usr/lib/x86_64-linux-gnu/libgnutls.so.30: symbol _idn2_punycode_decode version IDN2_0.0.0 not defined in file libidn2.so.0 with link time reference /usr/lib/apt/methods/http: relocation error: /usr/lib/x86_64-linux-gnu/libgnutls.so.30: symbol _idn2_punycode_decode version IDN2_0.0.0 not defined in file libidn2.so.0 with link time reference /usr/lib/apt/methods/http: relocation error: /usr/lib/x86_64-linux-gnu/libgnutls.so.30: symbol _idn2_punycode_decode version IDN2_0.0.0 not defined in file libidn2.so.0 with link time reference /usr/lib/apt/methods/http: relocation error: /usr/lib/x86_64-linux-gnu/libgnutls.so.30: symbol _idn2_punycode_decode version IDN2_0.0.0 not defined in file libidn2.so.0 with link time reference /usr/lib/apt/methods/http: relocation error: /usr/lib/x86_64-linux-gnu/libgnutls.so.30: symbol _idn2_punycode_decode version IDN2_0.0.0 not defined in file libidn2.so.0 with link time reference /usr/lib/apt/methods/http: relocation error: /usr/lib/x86_64-linux-gnu/libgnutls.so.30: symbol _idn2_punycode_decode version IDN2_0.0.0 not defined in file libidn2.so.0 with link time reference Reading package lists...

Soluția (cel puțin temporară) este următoarea:

# wget http://ftp.us.debian.org/debian/pool/main/libi/libidn2/libidn2-0_2.0.5-1_amd64.deb # sudo dpkg -i libidn2-0_2.0.5-1_amd64.deb 

După instalare, un apt-get update && apt-get upgrade -y ar trebui să rezolve problemele.
