Linux Tips

dpkg errors

I wasn’t able to get apt-get to do anything. The problem was that my /boot partition was full.

I checked that this was the problem using

df -i

and

df -i

I then iterated on the following two commands:

dpkg -l linux-{image,headers}-"[0-9]*" | awk '/^ii/{ print $2}' | grep -v -e `uname -r | cut -f1,2 -d"-"` | grep -e '[0-9]' | xargs sudo apt-get -y -f purge

and

sudo apt-get -f autoremove

Somehow it worked.

curl certs

Sometimes when updating a Julia package that uses curl to get dependencies I get the following error:

================================[ BUILD ERRORS ]================================

WARNING: Blosc had build errors.

- packages with build errors remain installed in /home/ap/.julia/v0.3
- build the package(s) and all dependencies with `Pkg.build("Blosc")`
- build a single package by running its `deps/build.jl` script

===============================================================================

To fix it I entered the following from the terminal

echo "cacert=/etc/ssl/certs/ca-certificates.crt" >> ~/.curlrc

That fixed it
