obsA7-002 perl-baseの更新

初回のaptitude safe-upgrade で perl-base が更新できなかったときの回避。この処置が正しいかは怪しい。

1.upgradeでのエラーの症状

root@obsa7:/usr/bin# aptitude update
root@obsa7:/usr/bin# aptitude safe-upgrade

root@obsa7:/usr/bin#

(注意1): No such file or directory のエラーが出る。どうも./usr/bin/perl5.14.2が足をひっぱってそうなので、

root@obsa7:/usr/bin# ls -l perl*
-rwxr-xr-x 1 root root 9792 Apr 12  2013 perl
-rwxr-xr-x 1 root root 9792 Apr 12  2013 perl5.14.2
root@obsa7:/usr/bin# mv perl5.14.2 perl5.14.2.bak

root@obsa7:/.rw/usr/bin# mv perl5.14.2 perl5.14.2_BAK
root@obsa7:/.rw/usr/bin# cd /usr/bin

root@obsa7:/usr/bin# cp perl5.14.2_BAK perl5.14.2
root@obsa7:/usr/bin# ls -l perl*
-rwxr-xr-x 2 root root 9792 Apr 12  2013 perl
-rwxr-xr-x 1 root root 9792 Dec 24 10:10 perl5.14.2
-rwxr-xr-x 1 root root 9792 Apr 12  2013 perl5.14.2_BAK
root@obsa7:/usr/bin#

(後で_BAKを消す)
root@obsa7:/.rw/usr/bin# rm perl5.14.2_BAK

この/usr/bin/perl5.14.2が変更できなくてInput/output errorになっていると思われ、これを回避するために/.rwでリネームして/usr/binでコピーしてみた。そして、再aptitude safe-upgrade するとエラー無く通った。

root@obsa7:/usr/bin# aptitude safe-upgrade

おお、kernel-imageも自動でアップデート。この時のsource-listは初期の標準のもの。
