upgrading bor-*-*-config_v*.deb deletes provided files

[etam]

System information

Bor client version: 0.4.0

Heimdall client version: not relevant

OS & Version: Linux Ubuntu 20.04

Environment: Polygon Mainnet

Type of node: Sentry

Overview of the problem

The postrm script in bor-mainnet-sentry-config_v0.4.0-amd64.deb deletes files managed by dpkg.

Reproduction Steps

• Install latest 0.3.* config package (for example dpkg -i bor-mainnet-sentry-config_v0.3.9-amd64.deb)
• Update to 0.4.0 (dpkg -i bor-mainnet-sentry-config_v0.4.0-amd64.deb)

Logs / Traces / Output / Error Messages

The result is that files

• /lib/systemd/system/bor.service
• /var/lib/bor/config.toml

do not exist

Additional Information

The bor-mainnet-sentry-config_v0.4.0-amd64.deb package contains a postrm script that contains

sudo rm -rf /var/lib/bor/config.toml
sudo rm -rf /lib/systemd/system/bor.service

Those files are provided by the package itself and are managed by dpkg.

The man dpkg under -i, --install package-file... says

4. Unpack the new files [...]
5. If another version of the same package was installed before the new installation, execute the postrm script of the old package. [...]

So when upgrading the package:

• dpkg unpacks the files
• the postrm script deletes them
