Koha and Debian 9 and /tmp
#Linux#Software#Debian#Koha#Apache
I recently upgraded our library’s Koha installation to 19.11 (from 19.05), and at the same time upgraded the operating system from Debian 8 to Debian 9. This created a problem with the “Stage MARC records for import” feature in Koha. I could upload the file, and using ssh I could see the file in /tmp. But then Koha would complain that the file did not exist when it tried to import it.

Our library has enabled the cart feature in the Koha OPAC, which allows patrons to create a list of books they’re interested in. Some patrons have used the “Send” feature of the cart, which allows them to send the cart to an arbitrary email address. But there have been several problems with this, such as bad email addresses causing the emails to be redirected to the sysadmin (me). I decided to suppress the ability to send the cart by hiding the “Send” button. In Administration / Global system preferences, edit the OPACUserJS preference to look like this:

ThinkPad T450s ethernet and suspend
There seems to be a problem with the ethernet device on a ThinkPad T450s (and possibly other machines using Intel E1000 ethernet devices), where Network Manager (NM) hangs trying to initialize the device after a suspend/resume cycle. After a resume, NM shows a spinning icon for about 10 seconds trying to get an IP address, and it eventually gives up. Telling NM to try again results in the same failure.
