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
