Why so much space to be freed in du?

[drb]

I'm a bit suspicious as to why so much space will be freed with no removals and 11 new installations - 204MB to be freed. Any ideas why?

After this operation, 204 MB disk space will be freed.

say "no" to the complete upgrade and try installing (dry run) listed packages one after another. I'd suspect libreoffice cleaned up something.

[edit], ok, not every of >100 but basic ones ;-)

[drb]

OK, thanks, will try that. 204MB seems a lot of 'cleaning up' though!

[kokurya]

Same here but it doesn't seem to be connected with Office.
Laptop with Libreoffice = 63 mb are going to be freed
File-/Torrentserver without Libreoffice = 205 mb are freed

[dibl]

It is unusual to see that much space freed, but I just ran this d-u on my HP laptop, and it seems to be working just fine.

Do you want to continue? [Y/n]

[drb]

Did you run the du dibl?

[dibl]

Yes, I ran it on my laptop and there's no indication of any problem.  I'll update my desktop system later today, as well.

[kokurya]

Also did a DU no problem so far.
