Jennings has been running Ubuntu 18.04 for a while in partition \/dev\/mapper\/ubuntu--vg-root2<\/code>. Rather than upgrade it to 20.04, I thought I’d upgrade the older Ubuntu 16.04 installation in partition \/dev\/mapper\/ubuntu--vg-root<\/code>. Here’s what needed to change:<\/p>\n\n\n\n

Change from Dropbox to pCloud<\/h2>\n\n\n\n

This is as simple as installing from pcloud.com<\/a> and setting up a sync from ~\/pcloud-sync<\/code> to Applications\/Keepass2Android<\/code>.<\/p>\n\n\n\n

Upgrade Keepass<\/h2>\n\n\n\n

Since upgrading to Keepass 2 (the .kdbx format), I don’t have to keep locking KeepassX to an old 1.x version. Unlock the version of KeepassX, delete it and install KeepassXC. Add the keyboard shortcut Ctrl+Alt+A for autotype.<\/p>\n\n\n\n

DS411+II NAS Mounts<\/h2>\n\n\n\n

A new router has been installed since Ubuntu 16.04 was running. The old router would create DNS entries for each client based on their host name, so ds411p2<\/code> was valid. The new one, a Comcast XB6, doesn’t do that. The hosts are reachable through .local<\/code> names, so the NAS needs to be referenced as ds411p2.local<\/code> now. This fix was made in \/etc\/fstab<\/code>, as well as the fix to mount CIFS with the mount option vers=1.0 (because the NAS is old and doesn’t support the newer default version).<\/p>\n\n\n\n

Fix Darktable Configuration<\/h2>\n\n\n\n

The files in ~\/.config\/darktable<\/code> were from whatever version of Darktable was available in the Ubuntu 16 repositories and the current version, 3.0.1, didn’t like them. Replacing that directory tree with the one from the Ubuntu 18 installation fixed the problem.<\/p>\n\n\n\n

HP Color LaserJet Pro MFP m477 Fdn Scanning<\/h2>\n\n\n\n

(Read through this whole section before doing anything, because it contains steps that didn’t work.)<\/p>\n\n\n\n

This printer is an all-in-one and it works out of the box, except for scanning. For that, a proprietary plugin must be installed:<\/p>\n\n\n\n

https:\/\/developers.hp.com\/hp-linux-imaging-and-printing\/binary_plugin.html<\/a><\/p>\n\n\n\n

Unfortunately, the plugin doesn’t install on Ubuntu 20. hp-setup was an old version. It wasn’t upgraded because it wasn’t installed from the hplip package. To fix, find the old installation (it was 3.18.5) and run sudo make uninstall from there. <\/p>\n\n\n\n

Then reinstall hplip:<\/p>\n\n\n\n

sudo apt remove hplip\nsudo apt autoremove\nsudo apt install hplip hplip-gui<\/pre>\n\n\n\n
That failed, so I removed those packages and downloaded hplip from https:\/\/developers.hp.com\/hp-linux-imaging-and-printing\/gethplip<\/a> and installed using defaults, but python-pyqt5 and python-dbus.mainloop.pyqt5 failed.  <\/p>\n\n\n\n
GUI installation doesn’t work on Ubuntu 20 yet, so I ran again, selecting all defaults except:<\/p>\n\n\n\n
