The road begins on a currently updated OpenBSD 7.3 release. That means, the following commands
|
|
have been initiated and completed without errors.
|
|
|
|
```console
|
|
$ doas syspatch
|
|
$ doas fw_update
|
|
fw_update: added none; updated none; kept intel,inteldrm,iwn,uvideo,vmm
|

## Backups never hurt
|
|
|
|
We will save a list of the currently installed packages. Just for the case...
|
|
|

```console

$ pkg_info -mz >package-list.txt

At this point I spent a few hours looking for a solution -- I haven't found one yet. I will

probably don't look at current to soon.

|
|
## Revert back to -release
|
|
|
|
Nonetheless, I could not fix this and I wanted to revert my system back to -release.
|
|
There is no command to downgrade from -snapshot back to -release so we have to re-install the
|
|
base files of the last -release.
|
|
|
|
Boot the `bsd.rd` kernel which will boot up to this prompt:

To apply the latest AMD microcode updates, we still have to execute two other
|
|
commands.
|
|
|
|
```console
|
|
$ doas fw_update
|
|
fw_update: added none; updated none; kept intel,inteldrm,iwn,uvideo,vmm
|
|
$ doas installboot -v sd0

If for any reasons the packages cannot be updated because we still have newer packages
|
|
installed (from snapshots) than available on release:
|
|
|
|
Remove them all and re-install them based on the backup (package-list.txt) we did earlier.
|
|
|
|
```console
|
|
$ doas pkg_delete -X
|
|

Re-install them based on our backup file.

New and changed readme(s):

|
|
--- +fish-3.6.0p0 -------------------
|
|
You may wish to add /usr/local/share/fish/man to /etc/man.conf
|
|
--- +i3status-2.14 -------------------
|
|
Before running i3status, a configuration file needs to be created.
|
|
Copy the provided /usr/local/share/examples/i3status/i3status.conf
|
|
to ~/.i3status.conf and modify as necessary.
|
|
```
|

Again, a `shutdown -r now` reboots the computer. Now all should be
|
|
on an updated OpenBSD 7.3 (release) again.
