• latex in matplotlib not working. Installed texlive-latex-extra (380MB!)
• in one instance shutdown after software update resulted in the laptop hanging on the Toshiba dashboard. Repaired by simply inserting the live USB, starting live ubuntu, visiting the SSD and shutting down. Not understood how, but it worked.
• sometimes printing problems:
  • Libreoffice sees no credit. Possible cause: passwords are wrong or unset, correct all by
    sudo vim /etc/cups/printers.conf
    sudo service cups restart
  • evince requires password instead of using the printer settings. (see below)
• printer under LibreOffice: symptom prints ultra-small with plain postscript driver; solution made new printer with TASKalfa_3551ici.PPD downloaded from the Kyocera site. Now prints also in color and right size. Reinstalling the printer from scratch (windows samba, with use PPD driver) did the job.

  10 2 * * 5 /root/bin/backup_all_lacie.sh
  10 2 * * 4 /root/bin/backup_musr_HDD.sh
  30 2 * * 4 /root/bin/backup_musr_lacie.sh

• papercut, see 13.10, but remember that one has to run it from /usr/local/bin/papercut-client/pc-client-linux.sh
• jnc copy from .juniper_networks, remember to copy also ncsvc and set it chmod +s
• installed openafs from repository, sudo apt-get install openafs-krb5, copied /etc/openafs/ThisCell and /etc/openafs/cacheinfo, plus
  sudo /etc/init.d/openafs-client restart
  perhaps after kernel updates needs also
  sudo module-assistant auto-build openafs-modules
sudo m-a install openafs-modules-source
• run thunderbird, close it immediately, cd to .thunderbird and rm -rf *, then rsync -av /media/roberto.derenzi/.../home/roberto.derenzi/.thunderbird/ .thunderbird/. Same with .mozilla/

• reboot on 14.04, sudo passwd root to create root, apt-det update, apt-get upgrade to be updated (now the loader is on the HD with 13.10, /dev/sda)
• doesn't boot, booted from 13.10, sudo update-grub, sudo grub-install (recognizes 14.04 on SSD and adds it)
• installed Ubuntu 10.04 with /dev/sdb as boot loader, /dev/sdb1 as /
• GParted SSD by hand, /dev/sdb ad DOS, one partition 244 GB ext4, one swap 8 GB
• Installed from USB on SSD on caddy. To mount on caddy remove the plastic spacer at the opposite end to the connector, unscrew all fixing screws out of the way, slide the SDD in place, replace the spacer and fix with the screws. Had to open all the back, HD lid first, docking connector also, there is a screw holding the CDROM to its own connector. Need to swap HDD and SSD after initial 14.04 setup.
