Ubuntu 18.04 Hplip Scanner Problem


Printing works on Ubuntu 18.04 fine, but after a recent update, scanning on an HP MFP277 results in a SANE I/O Error 9.


Remove HPLIP:
$ sudo apt-get purge hplip
Download HP Public Key (Optional Step):
$ /usr/bin/gpg --keyserver --recv-keys 0xA59047B9
Download HPLIP 19.x directly from HP, rather than from Ubuntu.
$ ./
And select all the default responses.  Install plugins if requested:
$ hp-plugin
Checking for network connection...Downloading plug-in from: Plugin is not accessible. Trying to download it from fallback location: []Receiving digital keys: /usr/bin/gpg --homedir /home/steve/.hplip/.gnupg --no-permission-warning --keyserver --recv-keys 0x4ABA2F66DBD5A95894910E0673D770CDA59047B9
If the plugin is not accessible, as shown in the above example, simply download and execute the proposed plugin run file.
$ wget$ sh ./
If the plugin install fails with the following error:
Plugin installation failederror: Python gobject/dbus may be not installederror: Plug-in install failed.
Ensure that a reboot following a previous upgrade is not pending.
