Openbsd Packages
If you are unfamiliar with OpenBSD's package system, please read the FAQ first.
To install a package (like nvi):
$ doas pkg_add nvi
To delete a package:
$ doas pkg_delete nvi
To delete unused dependencies:
$ doas pkg_delete -a
To find a package from repositories:
$ doas pkg_info -Q nvi
To learn more about a package:
$ doas pkg_info nvi
Troubleshooting
/etc/installurl
On occasion, you may encounter errors:
$ doas pkg_add package
https://cdn.openbsd.org/pub/OpenBSD/7.1/packages-stable/amd64/: ftp: cdn.openbsd.org: no address associated with name
https://cdn.openbsd.org/pub/OpenBSD/7.1/packages/amd64/: ftp: cdn.openbsd.org: no address associated with name
https://cdn.openbsd.org/pub/OpenBSD/7.1/packages/amd64/: empty
Can't find package
In the above, your system can't resolve the name cdn.openbsd.org. This could be due to your local nameservers, or it could be due to a mirror having issues.
To change the mirror, edit /etc/installurl to use a different mirror from the list of OpenBSD mirrors.
If the issue is your local nameservers, you may want to configure unbound.
