アップグレード中にプロンプトから質問されたこと
以下、主要な質問事項です。コメント(#の後)に概要を書いています。
Reading cache
Checking package manager
Continue running under SSH?
This session appears to be running under ssh. It is not recommended
to perform a upgrade over ssh currently because in case of failure it
is harder to recover.
If you continue, an additional ssh daemon will be started at port
'1022'.
Do you want to continue?
# SSHのポートを追加するか
# → y
Starting additional sshd
To make recovery in case of failure easier, an additional sshd will
be started on port '1022'. If anything goes wrong with the running
ssh you can still connect to the additional one.
If you run a firewall, you may need to temporarily open this port. As
this is potentially dangerous it's not done automatically. You can
open the port with e.g.:
'iptables -I INPUT -p tcp --dport 1022 -j ACCEPT'
To continue please press [ENTER]
# 設定を変更するか
# → Enter
Do you want to start the upgrade?
4 packages are going to be removed. 85 new packages are going to be
installed. 555 packages are going to be upgraded.
You have to download a total of 247 M. This download will take about
49 seconds with a 40Mbit connection and about 6 minutes with a 5Mbit
connection.
Fetching and installing the upgrade can take several hours. Once the
download has finished, the process cannot be canceled.

There are services installed on your system which need to be restarted when certain libraries, such as libpam, libc, and libssl, are upgraded. Since these restarts may cause interruptions of service for the system, you will x
x normally be prompted on each upgrade for the list of services you wish to restart. You can choose this option to avoid being prompted; instead, all necessary restarts will be done for you automatically so you can avoid being x
x asked questions on each library upgrade. x
x x
x Restart services during package upgrades without asking?
# アップグレード時、各種サービスを再起動前にプロンプトでy/nを確認するか
# → 質問されるのがめんどいので yes
# この間、SSH等の設定変更を行うか訊いてきます。プロンプトの選択を変えずに先に進みました
# keep the local version currently installed
Remove obsolete packages?
# 不要パッケージの削除

System upgrade is complete.
Restart required
To finish the upgrade, a restart is required.
If you select 'y' the system will be restarted.
