Ubuntuで/bootがいっぱいになる件 - エロサイトの作り方

Ansibleでエラー

apt-getやaptitudeでの更新でも起こるようですが、今回はAnsibleで発生したのでとりあえずログをぺたり。

ディスクの空きが無い？

と言ってますね。

いやいや、まだあるでしょ。

……と思ったら、/bootが100%使用中だった。

update-initramfs: failed for /boot/initrd.img-3.13.0-43-generic with 1.

とログにあるように、ファイルは/bootに置こうとしたらしい。

/bootの中身

とりあえず/bootの中身を確認。

なんか色々あるけど、わからん。

aptitude autoclean効きます？

$ sudo aptitude autoclean
Freed 0 B of disk space

$ df -h

/dev/sda1                     236M  223M  981K 100% /boot

ダメだった。

じゃあ、apt-get autoremoveは効きます？

$ sudo apt-get autoremove

こ　う　か　は　ば　つ　ぐ　ん　だ　！

というわけで

定期的に実行しないとダメなのかな。
