Error installing 5.1

[Roland Mayne]

I get this error "sed: can't read /etc/weewx/udev/weewx.rules: No such file or directory" during installation. 

This file realy don't exist.

[Tom Keffer]

Geez, how about a little more information?

- Which operating system are you using?

- Was this a new install, or an upgrade?

- How about the context of the error? What did it say before and after? In fact, give the complete transcript, including what you typed.

- Any other useful information that you can think of.

Folks, getting this error as well on a Rasberry Pi 3B running Raspian Bookworm (with current updates) after removing (via "sudo apt remove weewx", plus manually deleting /etc/weewx) and reinstalling via "sudo apt install weewx".  Confirmed /etc/weewx/udev exists but is empty:

Installing udev rules

sed: can't read /etc/weewx/udev/weewx.rules: No such file or directory

dpkg: error processing package weewx (--configure):
 installed weewx package post-installation script subprocess returned error exit
 status 2
Processing triggers for man-db (2.11.2-2) ...
Errors were encountered while processing:
 weewx
E: Sub-process /usr/bin/dpkg returned an error code (1)

Any thoughts would be appreciated.

there must have been some failure earlier in the installation process resulting in no udev rules file (weewx.rules) copied into the directory /etc/weewx/udev

my first guess is that you tried to install over an existing /etc/weewx directory, and a permissions/ownership problem prevent the copy. however, you indicated that you deleted /etc/weewx

were there any other warnings in the installer output? could you post all of the installer output from when you invoked 'sudo apt install weewx'?

is there anything else in the /etc/weewx directory after the failed installation? could you do 'ls -lR /etc/weewx' and post the result?

[Ted Lavino]

Hello Mathew, your assistance is much appreciated.

I removed weewx following the process I described above using "sudo apt remove weewx" plus "sudo rm -r /etc/weewx" as the apt remove weewx process did not remove all files, and then reinstalled weewx via "sudo apt install weewx"

Cheers,

something is preventing apt from copying the weewx.rules file (as well as many others) from the .deb package into the new /etc/weewx directory. so when the postinst script tries to do a configure, it fails.

you might be able to get more information from the apt log. take a look in /var/log/apt/term.log for signs of the weewx install/remove.

it looks like you had weewx with rc (not systemd) installed before this installation - did you upgrade from an older version of weewx? was weewx installed using a non-apt method before you tried the apt install of weewx? did you upgrade the operating system or is this on a clean install of debian 12?

try doing a complete purge of weewx, followed by an install.

first make a backup copy of your weewx database if you have not done so already:

sudo cp -p /var/lib/weewx/weewx.sdb ~

then you can purge weewx:

sudo apt purge weewx
sudo rm -r /var/www/html/weewx
sudo rm -r /var/lib/weewx
sudo rm -r /etc/weewx
sudo rm /etc/default/weewx

if an install after this still fails, then you might have to do an even deeper purge by doing those steps again, plus the following to remove the weewx user and group before doing a clean install:

sudo gpasswd -d $USER weewx
sudo userdel weewx
sudo groupdel weewx

the instructions for a complete purge are in the 'uninstall' section of the debian quick-start

Hello Matthew, yes this was a initially a version 4 install that I upgraded, then tried to wipe and then tried start from scratch in terms of both OS and the weewx application when the upgrade went sideways. Likely at one point I had two installation types working at cross purposes. Will purge and reinstall...
