pacman -Syuでハマった点(2015/10/16) libncursesw.so.5, if_name

Last updated at Posted at 2015-10-15

ログインができなくなる(libncursesw.so.5がない)

/usr/bin/bash: error while loading shared libraries: libncursesw.so.5: cannot open shared object file: No such file or directory
error: command failed to execute correctly

sudo ln -s /usr/lib/libncursesw.so.6  /usr/lib/libncursesw.so.5

これでログインできるようになった。

ネットワークデバイス名が変わった(KVM)

ネットワーク再設定

cd /etc/netctl/
sudo mv eth0 ens18
/etc/netctl/ens18
-Interface='eth0'
+Interface='ens18'

有効化

ens18をstart
systemctl start netctl@ens18
ens18を有効化
# sudo netctl enable 
ln -s '/etc/systemd/system/netctl@ens18.service' '/etc/systemd/system/multi-user.target.wants/netctl@ens18.service'
eth0を無効化
# netctl disable eth0                           
Removed symlink /etc/systemd/system/multi-user.target.wants/netctl@eth0.service.
