One of the best things about Linux is its unmatched level of flexibility. No other operating system provides the same level of freedom to users because they are not open-source. Thanks to its open and free nature, you can break and repair the system itself, and that’s just awesome when it comes to embracing a spirit of experimentation.
Yesterday, I had a tough time with my home Linux server. I talk about it a lot in my blogging because right now, it’s essentially my tech universe’s hub spot. It serves as not only my Dropbox alternative but also my go-to place for daily Linux experimentation.
Okay, let’s get back on track. I had trouble logging in to the MySQL server as the root user, so I uninstalled and reinstalled it. But I ran into a lot of unexpected issues along the way. I tried to find solutions by googling and came across some pages with suggestions. Unfortunately, following those suggestions only made things worse because I accidentally deleted some important files.
One of the files I deleted was the list of apt updates/upgrades, so as you can imagine, I had trouble updating or upgrading any software on the server.
And today, when I executed ‘sudo apt upgrade’ command, I got the below error message. There wasn’t enough space for /var/cache/apt/archives/.
$ sudo apt upgrade
...
E: You don't have enough free space in /var/cache/apt/archives/.So, I googled again and found one possible solution to it – so, here, I’ll share how I solved the issue.
Thankfully, I had already made enough room on the system by mounting and partitioning external HDDs, so all I did was redirect ‘/var/cache/apt/’ to one of the partitioned directories.
$ sudo apt autoclean
$ sudo mv /var/cache/apt/ /path/to/partitioned_directry/new_apt
$ sudo ln -s /path/to/partitioned_directry/new_apt /var/cache/apt$ ls -l /var/cache/
...
lrwxrwxrwx 1 root root 37 Feb 2 16:36 apt -> /path/to/partitioned_directry/new_apt
And it worked!! I was successfully able to execute the ‘sudo apt update’ command this time!
Linux is so fun to interact with!
No Linux, No Life!
