Dotaz: Nefunkční debian wheezy - nejde ani chroot

[majales]

Dobrý den Nevěděli byste někdo kde hledat problém. Po apt-get upgrade se mi nedaří opětovně rozjet instalace debian wheezy. Při bootu to hodí následující chybu:

/sbin/init: error while loading shared libraries: libsepol.so.1: cannot open shared object file: no such file or directory

A pak následuje samozřejmě Kernel panic..

Pokus o chroot se nezdaří zase s následující hláškou:

sudo chroot /mnt/debian-virt /bin/bash
/bin/bash error while loading shared libraries: libtinfo.so.5: cannot open shared object file: no such file or directory

Nevíte někdo kde může být problém.

Systém je vybudován na sw raid 6 poli a lvm. Disky jsem projet fsck a zdá se že je vše v pořádku. Akorát se při tom update instalovalo nové mdadm.

Podíval bych se, jestli ty knihovny opravdu neexistují, a nakopíroval bych je tam z balíčku/jiného funkčního systému.

[majales]

Tak chroot se nakonec povedl pomocí chroot /mnt/debian-virt /bin/sh .. Ovšem je to k ničemu všechny příkazy končí takto:

ls: error while loading shared libraries: libselinux.so.1: cannot open shared object file: no such file or directory
cp: error while loading shared libraries: libselinux.so.1: cannot open shared object file: no such file or directory
mc: error while loading shared libraries: libslang.so.2: cannot open shared object file: no such file or directory

Soubory tam jsou a jdou zkopírovat. Tak teda vážně nevím co se pokazilo..

[Adamec]

a na disku ty soubory jsou ci ne???
ldconfig -p | grep libselinux.so.1

[Adamec]

sorry ... nejak jsem prehledl posledni vetu ..

kukni na
http://linux.101hacks.com/unix/ldconfig/

[majales]

Tak samotnej ldconfig zabral... Systém už jede, ale chyba se vrací po pokusech o vyřešení chybných závislostí...

[majales]

Tak nevím co s tím.. Jsou nějaké pomíchané libc6 knihovny a já se z toho neumím dostat. Jde o multiarch. Nevědel by někdo jak tento problém vyřešit? Nebo jde o bug Wheezyho?

Co byste radili? Přeinstalovat a vykašlat se na multiarch? Je to bug Wheezyho? Nebo jsem si nějak sám rozbil systém? Zatím nic z toho co jsem zkoušel nezabralo...

Vyzkoušel jsem, ale bohužel bez úspěchu. Problém je že v průběhu instalace se asi pošramotí linky na knihovny a proto to vždy končí chybou... Pak je potřeba to napravit pomocí ldconfig.. jinak nelze volat žádný ze standartních příkazů vyjma "cd"...

Tak zacni tim, ze si nainstalujes staticky slinkovany busybox (balik busybox-static).

[Bedňa]

Teda ja mám taký vlastný postup, keď sa mi dvakrát za život podarilo rozbiť balíčkovací systém:

Všetko pod rootom:

cd /var/lib/dpkg/info/
rm *
cd /var/lib/apt/lists/
rm *
apt-get clean
dpkg --configure -a
apt-get -f instal

Keď toto nezaberie, spravidla reinštalujem :) Teda pokiaľ ti beží selinux, ešte by sa dal použiť restorecon, ale neviem či to za to stojí.

Nejsem si jist nakolik je to relevantní, ale podobný průběh a chybové hlášky jsem zažil, když v Archu nevyšlo nahrazení /lib symlinkem na /usr/lib. Binárky se daly spouštět přes linker přímo: /usr/lib/ld-2.16.so /bin/ls a bylo potřeba ručně instalovat glibc. Nejde něco podobného použít nyní?

[2X4B-523P]

posledně mi wheezy nešel nainstalovat přes instalátor, ale přes debootstrap to prošlo v pohodě, mám podezření na bug/špatné vypálení instalačního CD (v mém příp. netinstall)
