Installation procedure for 2.4.27 for UDM/PRO bootscript

[goldriver2]

I tried to follow installation instruction but it seems that many changes as occured since the doc was updated the last time

First command to remove /etc/init.d/udm.sh does'nt exist

Wondering if I should continue with the rest of the process or anyway it won't work with 2.4.27

thanks

Here is the messages from installation
UniFi Dream Machine Pro version 2.4.27 was detected

Yes, UDM 2.4.7 firmware brought many changes and it will take some time before everything is working. I am also waiting on a singular DEB file I can download and apply to UDM offline after factory reset.

[TheWood1978]

Yeah as it said in the patch notes.

Note: Any 3rd party modifications made to the OS of the console will be lost after the upgrade, proceed with caution if you modified your console's OS.

Its deleted all data for on_boot.

It also seems to have removed unifi-os command too!

[SamErde]

I noticed the removal of the UniFi-os command set as well. What has replaced this? (Sorry if I'm missing an answer that has already been posted.)

[TheWood1978]

Hey. It looks to me like they have gone to a standard Linux build. I say this cos before ssh keys wouldn't take in the normal way. They had to be added in unifi-os. Now ya can ssh copy key directly to UDM and it now works same as any other Linux build.

[m4n63]

There is a new build to be found that at least installs clean on my 2.4.27.
link: https://unifi.boostchicken.io/udm-boot-2x_1.0.1_all.deb
I simply installed as follows:

dpkg -i udm-boot-2x_1.0.1_all.deb
Selectdpkg -i udm-boot-2x_1.0.1_all.deb
Selecting previously unselected package udm-boot-2x.

and then enable...

systemctl enable udm-boot 

and hmm.. this actually fails I just noticed.. and I think I found why... there is an error in the command, and if I edit and remove the blank space it seems to work as intended...
Here is a diff of what I changed

root@unify-dmp-01:/lib/systemd/system# diff udm-boot.service udm-boot.service.BAK

< ExecStart=bash -c 'mkdir -p /data/on_boot.d && find -L /data/on_boot.d -mindepth 1 -maxdepth 1 -type f -print0 | sort -z | xargs -0 -r -n 1 -- sh -c '\''if test -x "$0"; then echo "%n: running $0"; "$0"; else case "$0" in *.sh) echo "%n: sourcing $0"; . "$0";; *) echo "%n: ignoring $0";; esac; fi'\'

"$0";; *) echo "%n: ignoring $0";; esac; fi'\'

Then reload and start

systemctl daemon-reload
systemctl start udm-boot

and the on_boot.d is created..
I then did a reboot and it seems to work for me now.

Can confirm that @m4n63's method worked on v2.4.27 of UDMP, with the exception that the URL for the .deb package seems to be at https://unifi.boostchicken.io/udm-boot-v2+/udm-boot-2x_1.0.1_all.deb now.

[m4n63]

Upgraded to 2.5.17 today, and the /data/on_boot.d is retained, but the udm-boot-2x_1.0.1_all.deb is not automatically reinstalled after upgrade.
Not a huge deal, I just reinstalled it manually, and applied the fix above again.

[SGXander]

+1 for 2.5.17 and the above package installing after removing the errant space. Any ideas on where the /mnt/data/on_boot.d is now as the unifi-os shell isn't available any more

[m4n63]

+1 for 2.5.17 and the above package installing after removing the errant space. Any ideas on where the /mnt/data/on_boot.d is now as the unifi-os shell isn't available any more

The on_boot.d directory is directly under /data now.

Thanks for that. The directory doesn't exist though. I've made it and placed the same script I had before (just conditional dns forwarders) in there but not restarted to test it yet. Is the on-boot program simply looking for that dir or have I missed something resulting in it not being created?

It gets created automatically when you fix the error in the command in this file as described in my post above.

[SGXander]

not sure what's gone wrong there then. steps were:

cd /tmp
curl -L https://unifi.boostchicken.io/udm-boot-v2+/udm-boot-2x_1.0.1_all.deb -o udm-boot-2x_1.0.1_all.deb
dpkg -i udm-boot-2x_1.0.1_all.deb
cd /lib/systemd/system
vi udm-boot.service (remove errant space and save)
systemctl enable udm-boot
cd /data/
ls

I've made the folder manually and will try a restart later today to see if it works as intended. If so may be a bug?

[m4n63]

Install the .deb package
Then amend the command in /lib/systemd/system/udm-boot.service to read as below: (there is a space to remove)

ExecStart=bash -c 'mkdir -p /data/on_boot.d && find -L /data/on_boot.d -mindepth 1 -maxdepth 1 -type f -print0 | sort -z | xargs -0 -r -n 1 -- sh -c '''if test -x "$0"; then echo "%n: running $0"; "$0"; else case "$0" in *.sh) echo "%n: sourcing $0"; . "$0";; *) echo "%n: ignoring $0";; esac; fi''

remove these lines as well from the file as to handle errors better:
Restart=on-failure
RestartSec=5s

then reload:
systemctl daemon-reload

and start
systemctl start udm-boot

then the directory should be created if it does not already exist

so you probably missed the reload and start command

[m4n63]

cd /tmp

should work after restart, or use the reload / start commands as detailed in the post above

[SGXander]

ah looks like I did miss those out. Removed my dir and those restart lines from the service file then ran again and it made the dir for me. Thank you!

For anyone as daft as me here's my start-to-end:

cd /tmp
#download
curl -L https://unifi.boostchicken.io/udm-boot-v2+/udm-boot-2x_1.0.1_all.deb -o udm-boot-2x_1.0.1_all.deb
#install
dpkg -i udm-boot-2x_1.0.1_all.deb
#Remove restart lines
sed -i '/Restart=on-failure/d' /lib/systemd/system/udm-boot.service
sed -i '/RestartSec=5s/d' /lib/systemd/system/udm-boot.service
#correct exec line
sed -i 's/- c/-c/g' /lib/systemd/system/udm-boot.service
#enable reload and start
systemctl enable udm-boot
systemctl daemon-reload
systemctl start udm-boot

Will try a restart when finished with work for the day

[SGXander]

Has anyone tried this install on 3.0.20?

[m4n63]

I did the update from 2.5.17 -> 3.0.20 on my DMP today. Worked just as it did when I upgraded from 2.4.27 -> 2.5.17

steps:

1. apply update
2. reinstall .deb
3. apply fix/changes to /lib/systemd/system/udm-boot.service
4. exec these commands:
   systemctl daemon-reload
   systemctl start udm-boot

ping @SGXander

Star thanks for confirming. Will give it a go tonight. Help.ui.com wont let you raise tickets without updating to the latest version but I rely on a DNS view for daytoday so can't stomach upgrades without being sure! Wish they'd add forwarders to the network app!

[SGXander]

Confirmed working. Actually /data/on-boot.d and my script inside the dir were still present after the upgrade but blatted and rerun anyway.

[m4n63]

Upgraded from 3.0.20 to 3.1.15 today, same procedure as last time ;-)

So far all seems to work fine.

A few steps up ;-)
or below again

also, make sure you install the latest .deb..

#download
curl -L https://unifi.boostchicken.io/udm-boot-v2+/udm-boot-2x_1.0.1_all.deb -o udm-boot-2x_1.0.1_all.deb

Have the things from the sed lines above been fixed? Not looked at it yet will have an upgrade this weekend!

[m4n63]

No, the package in the link is still broken and need the fixes applied after install.

[SGXander]

fair enough thanks for confirming. has anyone gone to 3.1.15 yet?

[m4n63]

Yes, it worked the same way as last time for me.

[SGXander]

anyone got the .deb mirrored? I'm getting "failed to resolve /ipns/unifi.boostchicken.io/udm-boot-v2+/udm-boot-2x_1.0.1_all.deb: could not resolve name" from https://unifi.boostchicken.io/udm-boot-v2+/udm-boot-2x_1.0.1_all.deb

[SGXander]

Also confirmed working on 3.1.15.
Looks like this link works so updated the commands below:

cd /tmp
#download
#old: curl -L https://unifi.boostchicken.io/udm-boot-v2+/udm-boot-2x_1.0.1_all.deb -o udm-boot-2x_1.0.1_all.deb
curl -L https://github.com/unifi-utilities/unifios-utilities/raw/main/on-boot-script-2.x/packages/udm-boot-2x_1.0.1_all.deb -o udm-boot-2x_1.0.1_all.deb
#install
dpkg -i udm-boot-2x_1.0.1_all.deb
#Remove restart lines
sed -i '/Restart=on-failure/d' /lib/systemd/system/udm-boot.service
sed -i '/RestartSec=5s/d' /lib/systemd/system/udm-boot.service
#correct exec line
sed -i 's/- c/-c/g' /lib/systemd/system/udm-boot.service
#create dirs
mkdir /mnt/data
mkdir /mnt/data/on_boot.d
#enable reload and start
systemctl enable udm-boot
systemctl daemon-reload
systemctl start udm-boot

Although it did not create the directory under /mnt this time I had to mkdir /mnt/data and mkdir /mnt/data/on_boot.d which I've added above too.

[ddkedr]

Hey, @SGXander @m4n63 ! Are you sure this space thing I still there?

I've just downloaded the file with the link below and I don't see this error

I did dpkg -c udm-boot-2x_1.0.1_all.deb and I get this Exec command

ExecStart=bash -c 'mkdir -p /data/on_boot.d && find -L /data/on_boot.d -mindepth 1 -maxdepth 1 -type f -print0 | sort -z | xargs -0 -r -n 1 -- sh -c '\''if test -x "$0"; then echo "%n: running $0"; "$0"; else case "$0" in *.sh) echo "%n: sourcing $0"; . "$0";; *) echo "%n: ignoring $0";; esac; fi'\'
RemainAfterExit=true

It seems totally fine.

Please, let me know if I'm looking at the wrong file

No, the package in the link is still broken and need the fixes applied after install.

I am still on UDMP firmware 2.5.17 and downloaded udm-boot with curl as shown above. However, I failed to install udm-boot:

root@UDMPRO:/tmp# dpkg -i udm-boot-2x_1.0.1_all.deb
dpkg: error: error executing hook '/usr/bin/systemd-cat -t ubnt-dpkg-status /sbin/ubnt-dpkg-status-pre', exit code 256

I am not familiar with the specialities of the linux system behind UDMP. I wonder whether 100% run partition is the root cause for the above problem:

Hey, @SGXander @m4n63 ! Are you sure this space thing I still there?

No. It seems this was fixed in this commit on Feb 22.

I've just downloaded the file with the link below and I don't see this error

Same here.

[fdcastel]

For reference. Installed on-boot-script-2.x today in a UDM-PRO running 3.1.16 following these steps.

Edit: moved actual steps to more appropriate issue related to UDM-PRO 3.0.

(this issue is for 2.4.x)
