== Upgrading Alpine 1.9.x that runs on HD/CF/USB ==
#REDIRECT [[Upgrading Alpine]]
This document applies to alpine which is installed on HardDisk(HD), CompactFlash(CF) or USB.<BR>
 
All examples/instructions/actions mentioned in this document should be executed on the box that you are planning to upgrade (unless you are instructed otherwise).
 
{{Upgrading_Alpine_environmentvars}}
 
== Download a new Alpine Linux release ==
Start by checking that you have enough space on your media.<BR>
You need at least 400MB available space.
df -h | grep "Filesystem\|$LBU_MEDIA"
 
Start downloading a new '.iso' and a '.sha1' file
cd /media/$LBU_MEDIA
wget -c {{Latest_1.9_alpine_iso-mirror}}{{Latest_1.9_alpine_iso-filename}}
wget http://dev.alpinelinux.org/alpine/v1.9/iso/{{Latest_1.9_alpine_iso-filename}}.sha1
 
Check integrity of the downloaded files ''(it might take some time)''
sha1sum -c {{Latest_1.9_alpine_iso-filename}}.sha1
''The output of the above command should say 'OK'.<BR>''
''If says 'FAILED', delete the iso file and download it again.''
 
== Copy the new release  ==
 
Mount the ISO.
mkdir /tmp/alpine-new
mount -t iso9660 {{Latest_1.9_alpine_iso-filename}} /tmp/alpine-new
 
Back up file that you have modified ''(below is a list of files that might need backing up)''<BR>
'''''syslinux.cfg:''' You might have modified it to show console on a serial port''
 
cp /media/$LBU_MEDIA/syslinux.cfg /media/$LBU_MEDIA/syslinux.cfg.my
 
Copy the files:
 
cd /tmp/alpine-new
rsync --delete -rltv .alpine-release * /media/$LBU_MEDIA/
 
Restore your backed up files ''(in case you had any)''
 
mv -f /media/$LBU_MEDIA/syslinux.cfg.my /media/$LBU_MEDIA/syslinux.cfg
 
Make sure that all files are permanently saved in right place
 
sync
 
{{Upgrading_Alpine_executeupgradescript}}
 
== Clean up ==
Clean up the downloaded/unpacked files
umount /tmp/alpine-new
rmdir /tmp/alpine-new
rm /media/$LBU_MEDIA/{{Latest_1.9_alpine_iso-filename}}
rm /media/$LBU_MEDIA/{{Latest_1.9_alpine_iso-filename}}.sha1
 
== Save changes ==
Now that all upgrades are done, we should save our settings to our media (which you hopefully have backed up).
lbu ci
 
== Rebooting ==
In most cases you will need to reboot Alpine (especially if there are changes in the kernel):
reboot
'''''Note:''' If you know what you are doing, you might not need to reboot.<BR>But make sure that all services affected by the upgrade are restarted.''
