解決方法

この場合、

E: The repository 'https://ppa.launchpadcontent.net/phablet-team/tools/ubuntu noble Release' does not have a Release file.

のURLのうち、

https://ppa.launchpadcontent.net/[ phablet-team/tools ]/ubuntu

の括弧内の文字列を確認します。

そして、その文字列の前に**ppa:**を付けて、リポジトリから削除します。

bash

sudo add-apt-repository --remove ppa:phablet-team/tools

これでエラーが出なければOKなのですが、自分の場合は以下のようなエラーが発生しました。

TimeoutError: [Errno 110] Connection timed out

単純にConnection time outしてます。

Time outの修正

以下の記事に同様の症状がありましたので紹介します。

ここではループバックインターフェースからすべてのネットワークインターフェースのiPv6を無効化します。

bash

sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1
sudo sysctl -w net.ipv6.conf.default.disable_ipv6=1
sudo sysctl -w net.ipv6.conf.lo.disable_ipv6=1

もし永続化するなら/etc/sysctl.confに書いてください。

/etc/sysctl.conf

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

• iPv6がOFFになっているかの確認。1が出力されていたらOKです。

bash

cat /proc/sys/net/ipv6/conf/all/disable_ipv6

そして最後にリポジトリを削除しましょう。

bash

sudo add-apt-repository --remove ppa:phablet-team/tools
