Debian 8 to 9¶

Update sources list¶

vim /etc/apt/sources.list

:%s/jessie/stretch/g

Upgrade the system¶

Check for Necessary Disk Space¶

apt-get -o APT::Get::Trivial-Only=true dist-upgrade

Update the sources¶

apt-get update

Minimal Upgrade¶

 apt-get upgrade

Full Upgrade¶

apt-get dist-upgrade

Common problems¶

iBackup¶

PT ticket #35194-19

header.pl and constants.pm are in the ibackup directory but perl on debian does not look in the local directory for @INC.
to fix copy both header.pl and Constants.pm into /etc/perl/

backupninja¶

until backupninja gets the fixes pushed out to the debian repo PT ticket #35353
add partitions = no to job 15

samba-ad-dc¶

if Samba is in AD-DC mode, it and winbind fail.
do these commands, then try to run the upgrade again

systemctl stop smbd nmbd winbind
systemctl disable smbd nmbd winbind
systemctl unmask samba-ad-dc
systemctl start samba-ad-dc
systemctl enable samba-ad-dc

Removing old versions of interpreters.¶

PHP5 (and Ruby 2.1) are not removed by default and will still be used if loaded!
If there is no need for these things to exist remove them with apt-get uninstall.
