I am running my openHAB 2.5.6 on a Raspberry Pi 3 Model B Plus Rev 1.3 (Raspbian GNU/Linux 10 (buster), Kernel = Linux 4.19.118-v7+). After I saw that there is now 2.5.7 available, I tried to update using the openhabian-config CLI tool.
After this operation, 127 MB of additional disk space will be used. apt-listchanges: Reading changelogs... (Reading database ... 70351 files and directories currently installed.) Preparing to unpack .../grafana_7.1.0_armhf.deb ... Unpacking grafana (7.1.0) over (2.6.0+dfsg-3+b1) ... dpkg: error processing archive /var/cache/apt/archives/grafana_7.1.0_armhf.deb (--unpack): trying to overwrite '/usr/share/grafana/public/vendor/angular-other/angular-strap.js', which is also in package grafana-data 2.6.0+dfsg-3 dpkg-deb: error: paste subprocess was killed by signal (Broken pipe) Errors were encountered while processing: /var/cache/apt/archives/grafana_7.1.0_armhf.deb Updating FireMotD available updates count ... 2020-07-23 19:16:12,587: FireMotD: Info: Action "save" E: Sub-process /usr/bin/dpkg returned an error code (1)
Then a prompt shows up telling me the “02 | Upgrade” failed.
I would try to remove Grafana, but I am not sure about the best way to remove it.
