Closed masuko-shingo closed 3 years ago

masuko-shingo commented 3 years ago

Jetsonnanoで研究室のWi-Fiに有線で接続しているとき、

$sudo apt install [パッケージ名]
$sudo apt update

などを実行しても

例

$sudo apt install libc6:armhf
[sudo] password for jetsonnano: 
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package libc6:armhf

上記のように、パッケージが見つからないというエラーメッセージが出る

解決方法

サイト https://forums.developer.nvidia.com/t/jetson-nano-sudo-apt-get-update-not-working-help/112980/12 を参考にして、 GoogleのpublicDNSサーバーに DNSを設定することで解決した。 端末を開き

$nmtui

を実行 Edit a connecitonを選択 EthernetのWired connection 1 を選択 IPv4　CONFIGURATIONのを選択 DNS serverにを選択して

8.8.8.8
8.8.4.4

の２項目を追加 IPv6　CONFIGURATIONの DNS serverにを選択して

2001:4860:4860:8888
2001:4860:4860:8844

の２項目を追加

上記の操作を行った後

$sudo apt update
$sudo apt install [パッケージ名]

を再度試すと実行された。

例

$sudo apt install libc6:armhf
[sudo] password for jetsonnano:
