Debian 9 to 10¶

Update sources list¶

check which sources exist that point to stretch

cd /etc/apt
grep -nr stretch .

Edit the main list, and any others that come up

vim /etc/apt/sources.list

:%s/stretch/buster/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

• if it asks whether to change /etc/apt/trusted.gpg.d/debian-archive-jessie-security-automatic.gpg, say yes
• other things it asks to change, say no, keep the existing file

Full Upgrade¶

apt-get dist-upgrade

Upgrade MySQL databases (if MySQL/MariaDB installed)¶

mysql_upgrade

Common problems¶

borg¶

• Changes needed to the borg backupninja jobs #48568-1
  • need to add encryption = none just above the passphrase
  • change the path to the directory to be the complete full path, not use the tilde for home, and must start with a slash

mysql backup checking¶

Newest version of mariadb doesn't have separate databases for information schema or performance schema, so remove the old backups of those.

cd /var/backups/mysql/sqldump
rm information_schema.sql.gz
rm performance_schema.sql.gz
